測定する in 30 Seconds
- To measure is to find out the size, amount, or degree of something.
- Used in science, health, engineering, and everyday life.
- Implies a precise or systematic determination.
- Conjugates like other する verbs.
The Japanese verb 測定する (sokutei suru) is a fundamental word used when you need to determine the extent, quantity, or dimension of something. It's the direct equivalent of 'to measure' in English. This verb is employed across a wide range of situations, from scientific experiments and engineering to everyday tasks like checking your height or the temperature. It implies a process of careful observation and calculation to obtain a specific value.
- Core Meaning
- To find out the size, amount, or degree of something using a tool or method.
- Usage Contexts
- Scientific research, medical examinations, engineering, construction, personal measurements (e.g., weight, height), quality control, statistical analysis.
科学者は新しい物質の密度を測定するために実験を行いました。
When you encounter 測定する, think of a deliberate action to quantify something. It's not just a casual guess; it involves a systematic approach. For instance, a doctor might 測定する a patient's blood pressure, a surveyor will 測定する land boundaries, and a chef might 測定する the ingredients for a recipe, though for ingredients, other verbs like 計る (hakaru) might be more common in casual settings.
この装置は、温度を正確に測定することができます。
- Key Concept
- The act of measurement implies obtaining a quantifiable result, often for comparison, analysis, or control.
In academic or technical fields, 測定する is almost always the verb of choice. For instance, when discussing the results of a survey, you might say that the data was used to 測定する public opinion. In engineering, engineers will 測定する stress, strain, dimensions, and many other properties of materials and structures. The word carries a sense of precision and scientific rigor.
As a verb, 測定する conjugates like other する (suru) verbs. The dictionary form is 測定する, the past tense is 測定した (sokutei shita), the continuous form is 測定している (sokutei shite iru), and the potential form is 測定できる (sokutei dekiru). You will often see it followed by particles like を (o) to indicate what is being measured.
- Basic Structure
- [Object] を 測定する ([Object] o sokutei suru)
医師は患者の血圧を測定した。
In more complex sentences, 測定する can be used with various grammatical structures. For example, you might use it in subordinate clauses or in conjunction with other verbs to describe a process. The key is to identify what is being measured (the object, usually marked by を) and the action of measuring itself.
- Expressing Capability
- This machine can measure accurately. この機械は正確に測定できる。
私たちは、新しい材料の強度を測定しています。
When describing a past event, use 測定した. If the measurement is ongoing or a state resulting from measurement, use 測定している. The ability to perform a measurement is expressed with 測定できる. The negative form is 測定できない (sokutei dekinai), meaning 'cannot measure'.
この調査では、消費者の満足度を測定することを目的としています。
- Purpose of Measurement
- The verb often appears in sentences describing the purpose of an experiment, tool, or study, such as ～を測定するために (wo sokutei suru tame ni - in order to measure ~).
You'll frequently encounter 測定する in news reports, especially those related to science, technology, economics, and health. For instance, a news segment might discuss how a new study measured the effects of a certain diet on heart health, or how economic indicators are being measured to assess the country's financial status. Scientific journals and academic lectures are prime locations for this term.
天気予報では、気温や湿度を測定するための観測データが使われています。
In educational settings, particularly in science and math classes, teachers use 測定する when explaining experiments or problems that involve calculations of size, weight, speed, or volume. Think about physics experiments where students might 測定する the acceleration of an object, or biology classes where they 測定する cell growth.
- Technical Manuals
- Instruction manuals for electronic devices, machinery, and scientific equipment often use 測定する to describe the functions of the product, such as 'this device measures X'.
Medical professionals use 測定する when referring to diagnostic procedures. A doctor might say, 「あなたの身長と体重を測定しましょう」 (Anata no shinchou to taijuu o sokutei shimashou - Let's measure your height and weight). Similarly, in hospitals, nurses routinely 測定する vital signs like heart rate, blood pressure, and body temperature.
この工場では、製品の品質を厳しく測定しています。
In construction and architecture, architects and engineers 測定する distances, angles, and dimensions to ensure accuracy in building plans and execution. You might hear discussions about measuring the load-bearing capacity of a bridge or measuring the precise angles for a roof.
One common pitfall for learners is confusing 測定する (sokutei suru) with similar-sounding or similarly meaning verbs like 計る (hakaru) and 測る (hakaru). While all relate to measuring, 測定する generally implies a more formal, scientific, or precise measurement, often involving specific instruments and a degree of analysis. Simply saying you 'measured' something casually might be better expressed with 計る in some contexts.
- Overuse in Casual Settings
- Using 測定する for very simple, everyday measurements where a more casual verb would suffice. For example, instead of saying 「部屋の広さを測定する」 (heya no hirosa o sokutei suru - to measure the room's size) in a very casual conversation, you might just say 「部屋の広さを測る」 (heya no hirosa o hakaru) or even just ask 「部屋はどれくらい？」 (heya wa dore kurai? - how big is the room?).
Incorrect: 私は料理の材料の量を測定するのが好きです。
Another mistake is improper conjugation or particle usage. While 測定する is a する verb, learners might sometimes treat it like a godan verb or use incorrect particles. Always remember that the object of measurement is typically marked by を (o).
- Misinterpreting Nuance
- Thinking 測定する is always the best choice for any kind of measurement. While it's a safe general term, context is key. For example, measuring time might use 計る or 測る more often than 測定する.
A less common but still possible error is using it to mean 'to estimate' or 'to guess'. 測定する specifically implies a more objective and quantifiable process, not a subjective approximation. If you mean to estimate, use words like 推定する (suitei suru) or 見積もる (mitsumoru).
Correct: 科学者は新しい薬の効果を測定するために、厳密な実験計画を立てました。
While 測定する is a versatile verb for 'to measure', Japanese offers several alternatives depending on the nuance and context. Understanding these differences will greatly enhance your vocabulary.
- 計る (hakaru - often written with Kanji like 計, 測, 量)
- This is a very common verb for 'to measure'. It can be used for a wide range of measurements, including physical quantities (weight, length, volume), time, and even abstract concepts like one's feelings or the success of something. It's generally more common in everyday speech than 測定する.
- 測る (hakaru - often written with Kanji like 測, 計, 量)
- Similar to 計る, this verb also means 'to measure'. It often implies measuring distance, dimensions, or checking something against a standard. In many contexts, 計る and 測る are interchangeable, but 測る can sometimes lean towards measuring physical space or depth.
Using 測定する:
この実験で得られたデータを測定する。
- 量る (hakaru - often written with Kanji like 量, 計, 測)
- This verb specifically refers to measuring quantity, often weight or volume. You'll see it used with scales (scale 量る - hakaru) or when measuring liquids or dry goods.
- 比較する (hikaku suru)
- Meaning 'to compare'. While not a direct synonym, comparison often follows measurement. You measure something to compare it with a standard or another item.
Using 計る:
体重を計る。
- 推定する (suitei suru)
- Meaning 'to estimate' or 'to approximate'. This is distinct from 測定する, which implies precise measurement.
- 分析する (bunseki suru)
- Meaning 'to analyze'. Measurement is often a precursor to analysis.
Using 量る:
砂糖を量る。
In summary, 測定する is best used for formal, scientific, or technical measurements. For more general or everyday measurements, 計る or 測る are often more appropriate. 量る is specific to measuring quantity, especially weight or volume.
How Formal Is It?
Fun Fact
The kanji 測 itself has a radical related to water (氵), suggesting its original use might have been related to measuring water depth. The combination with 定 emphasizes the precision and reliability of the measurement.
Pronunciation Guide
- Pronouncing 'u' in 'suru' too strongly or like 'you'. It should be a short, soft 'oo' sound.
- Adding an English 'r' sound to 'suru' which is different from the Japanese 'r' sound.
- Mispronouncing 'ei' in 'tei' as a diphthong like in 'say'; it's closer to 'tay'.
Difficulty Rating
At B1 level, understanding 測定する in reading is generally straightforward, especially when it appears in scientific, technical, or news contexts. The meaning is usually clear from the surrounding vocabulary and the context of measurement. However, complex scientific jargon or abstract concepts related to measurement might pose challenges.
For writing at B1, using 測定する correctly requires understanding its formal register and common collocations. Learners need to be mindful of using it in appropriate contexts and conjugating it properly. Overuse in casual situations or confusion with similar verbs can be common.
Speaking with 測定する at B1 level involves using it in relevant situations, such as discussing experiments or health check-ups. Learners need to practice natural pronunciation and correct sentence structure. Hesitation might occur when choosing between 測定する and other 'measure' verbs.
Recognizing 測定する when spoken at a normal pace is achievable at B1. The context of measurement (e.g., numbers, tools, scientific discussions) usually helps in identification. Fast or highly technical speech might present difficulties.

FigurativeEasily Confused
Both mean 'to measure' and are pronounced the same (hakaru) when written with certain kanji.
While both mean 'to measure,' 測定する is typically used for more formal, scientific, or precise measurements involving instruments and analysis. 計る is more general and frequently used in everyday situations for measuring things like weight, length, or time.
体重を<strong>計る</strong> (taijuu o hakaru - to measure weight, casual) vs. 物質の密度を<strong>測定する</strong> (busshitsu no mitsudo o sokutei suru - to measure the density of a substance, formal).
Another verb pronounced 'hakaru' with a similar meaning to 'measure'.
測る often implies measuring distance, depth, or checking something against a standard. It can sometimes be used interchangeably with 計る, but 測定する remains the more formal and scientific choice for precise quantitative determination.
距離を<strong>測る</strong> (kyori o hakaru - to measure distance, general) vs. 橋の耐荷重を<strong>測定する</strong> (hashi no taikajuu o sokutei suru - to measure the bridge's load-bearing capacity, formal).

量る is specifically used for measuring quantity, particularly weight or volume, such as when measuring ingredients for cooking. 測定する is a more general and formal term for measuring various properties.
砂糖を<strong>量る</strong> (satou o hakaru - to measure sugar, specific quantity) vs. 溶液の濃度を<strong>測定する</strong> (youeki no noudo o sokutei suru - to measure the concentration of a solution, formal).
Both relate to determining a value, but one is precise and the other is an approximation.
測定する means to measure precisely, aiming for an exact value using tools or methods. 推定する means to estimate or approximate, often when an exact measurement is difficult or impossible, or when making an educated guess.
正確な値を<strong>測定する</strong> (seikaku na atai o sokutei suru - to measure the exact value) vs. 被害額を<strong>推定する</strong> (higai gaku o suitei suru - to estimate the amount of damage).
Measurement is often a step in the process of analysis.
測定する is the act of determining a quantity or degree. 分析する is the process of examining something in detail to understand its nature or structure, often using measured data as input. You measure data first, then analyze it.
データを<strong>測定する</strong> (deeta o sokutei suru - to measure data) then データを<strong>分析する</strong> (deeta o bunseki suru - to analyze data).

Tips
Formality Matters
Remember that 測定する is generally more formal and scientific than 計る or 測る. Choose the verb that best fits the context and the level of formality you need.
Object Particle
The object being measured is almost always followed by the particle を (o). For example, 'measure the temperature' is 温度を測定する (ondo o sokutei suru).
Common Collocations
Learn common phrases like 距離を測定する (measure distance), 効果を測定する (measure effect), and 濃度を測定する (measure concentration) to use the verb more naturally.
Syllable Emphasis
Japanese pronunciation tends to have even stress. Practice pronouncing each syllable of 測定する clearly: so-ku-tei su-ru.
Contextual Learning
Instead of memorizing the word alone, try to learn it within sentences related to science, health, or engineering. This will help you grasp its usage and nuance.
Active Recall
Try to describe simple measurements you perform in your daily life using 測定する, even if it feels a bit formal. This active recall will reinforce your learning.
Precision in Culture
Understand that precision is valued in Japanese culture, especially in technical and scientific fields. This appreciation for accuracy is reflected in the usage of 測定する.
Distinguish from Estimation
Clearly differentiate 測定する (to measure precisely) from 推定する (to estimate). Measurement aims for accuracy, while estimation is an approximation.
Use in Reports
If you are writing reports or summaries of scientific experiments or technical procedures, 測定する is the appropriate verb to use for describing the measurement process.
Listen for Keywords
When listening to Japanese, pay attention to numbers, units, and context clues that suggest a measurement is being discussed, which will help you identify the use of 測定する.
Memorize It
Mnemonic
Imagine a scientist named 'Sokko' who always wears a 'tei' (tea) cup on his head. He meticulously measures everything around him for his experiments, always making sure his measurements are precise. So, 'Sokko' with his 'tei' cup is always 'measuring' (sokutei suru).
Visual Association
Picture a very precise, almost robotic scientist wearing a helmet with a built-in ruler and a digital display. This scientist is diligently measuring various objects with extreme care. The helmet itself could be stylized to resemble the kanji 測 and 定.
Word Web
Challenge
Try to describe three things you measured today, or three things you plan to measure tomorrow, using the verb 測定する in Japanese sentences. Focus on what you are measuring and why.
Word Origin
The word 測定する is composed of two kanji characters. 測 (soku) means 'to measure, gauge, sound out,' and 定 (tei) means 'to fix, decide, establish, define.' Together, they form a compound verb indicating the act of establishing a definite measurement.
Original meaning: The kanji 測 originates from ancient Chinese characters depicting a tool used for measuring depth or soundings. 定 emphasizes the idea of bringing something to a fixed, unchanging state, implying a definitive result.
Sino-Japanese (derived from Chinese characters)Cultural Context
No specific sensitivity concerns are associated with this word. It is a neutral term used in objective contexts.
In English, 'measure' is a very common and broad term. While 'measure' can be used in scientific contexts, it's also used very casually ('measure the distance to the store'). In Japanese, 測定する is more often reserved for formal or scientific contexts, with other verbs like 計る being more prevalent in casual speech for everyday measurements.

Frequently Asked Questions
10 questionsYou should use 測定する when you need to emphasize precision, formality, or a scientific/technical context. For example, in a lab report, when discussing medical measurements, or when describing engineering specifications, 測定する is the appropriate choice. For everyday tasks like measuring your height or the length of a room casually, 計る or 測る are more common and natural.
Yes, 測定する is a transitive verb and typically requires a direct object, which is what is being measured. This object is usually marked by the particle を (o). For example, 血圧を測定する (ketsuatsu o sokutei suru - to measure blood pressure).
While 測定する is primarily used for physical quantities, it can be used for abstract concepts when they are being quantified in a structured or scientific way. For example, 'consumer satisfaction' (消費者の満足度) or 'public opinion' (世論) can be 'measured' (測定する) through surveys and data analysis, though the measurement itself is indirect and based on collected data.
Common mistakes include using it in overly casual situations where 計る or 測る would be more natural, incorrect conjugation, or confusing it with verbs like 推定する (to estimate). It's also important to remember that 測定する implies a more objective and precise determination than mere estimation.
As a する (suru) verb, it conjugates like others. The dictionary form is 測定する (sokutei suru), past tense is 測定した (sokutei shita), continuous is 測定している (sokutei shite iru), potential is 測定できる (sokutei dekiru), and negative is 測定しない (sokutei shinai) or 測定できない (sokutei dekinai).
'To measure' is the closest direct translation. However, the nuance of 測定する often leans towards 'to ascertain,' 'to gauge,' or 'to quantify' in a scientific or formal manner, implying a deliberate and precise process.
Commonly measured items include physical properties like temperature, pressure, length, volume, weight, electrical current, and chemical concentrations. It's also used for more abstract but quantifiable metrics like performance, quality, or levels of pollution.
While technically possible, it's more common to use 計る (hakaru) or 測る (hakaru) when specifically referring to measuring time, like a stopwatch. 測定する might be used if you are measuring a duration within a scientific experiment where precision is paramount.
測定する is a general verb for 'to measure.' 計測する (keisoku suru) is a more technical term, often referring to the field of metrology (the science of measurement) or the act of measuring with specialized instruments, especially in engineering or scientific contexts. 測定する is the more common verb for general use.
For 測 (soku), imagine a water radical (氵) indicating measurement related to liquids or depth, combined with a tool. For 定 (tei), think of 'setting' or 'fixing' a value, making it definite. Together, they represent fixing a definite measurement.
