설명 等于 in your Level:

At the A1 level, students encounter '等于' (děngyú) primarily as a mathematical term. It is one of the first verbs learned in the context of numbers and basic arithmetic. The focus is on the formula: 'Number A + Number B = Number C'. For example, '一加一等于二' (1+1=2). Beginners learn that '等于' acts as the equals sign. At this stage, learners should not worry about metaphorical meanings. The key is to recognize the sound 'děngyú' and associate it with the '=' symbol. Teachers often use it to practice numbers from 1 to 100. It is a very stable and predictable word in this context, always appearing between the equation and the result. Students might also see it in very simple comparisons of quantity, such as '100 cents equals 1 dollar'. The goal for A1 is simply to use it to state facts about numbers and measurements accurately without adding extra words like 'is'.

At the A2 level, the use of '等于' (děngyú) expands slightly into basic measurements and everyday comparisons. Students learn to use it with units of time, currency, and weight. For instance, '六十分钟等于一小时' (60 minutes equals one hour) or '一千克等于两斤' (1 kilogram equals 2 jin). A2 learners begin to see that '等于' can link two different ways of saying the same thing. They might also encounter it in very simple logical statements, such as '没去等于不去' (Not going is the same as not wanting to go), though this is more common at B1. The main challenge at A2 is distinguishing '等于' from '是' (shì). While '是' is for identity (I am a student), '等于' is for equivalence (A is the same as B in value). Learners are encouraged to use '等于' when there is a sense of calculation or conversion involved.

At the B1 level, '等于' (děngyú) becomes a powerful tool for expression beyond math. This is the stage where the metaphorical and logical uses become prominent. B1 students learn to equate actions with consequences or states of mind. For example, '沉默等于承认' (Silence equals admission) or '放弃等于失败' (Giving up equals failure). The word is often used with the adverb '就' (jiù) for emphasis: '不努力就等于自杀' (Not working hard is basically suicide - a common hyperbolic expression). At this level, students should understand the nuance that '等于' implies a necessary or logical result. They also begin to distinguish '等于' from '相当于' (equivalent to) and '相等' (equal in quantity). B1 learners are expected to use '等于' in discussions about habits, lifestyle, and basic opinions to show the relationship between two concepts.

At the B2 level, '等于' (děngyú) is used with greater precision in complex arguments. Students learn to use it to define parameters in professional or academic contexts. For example, '这种行为等于干涉内政' (This kind of behavior is equivalent to interfering in internal affairs). B2 learners use '等于' to synthesize information and make strong, definitive claims. They also handle the negative form '不等于' (does not equal) with more sophistication, often using it to clarify nuanced differences: '理解不等于赞成' (Understanding does not equal agreeing). At this stage, the register becomes important; students learn when to use '等于' versus more formal alternatives like '等同于' or '同于'. They also recognize '等于' in idiomatic expressions and can use it to explain the logic behind cultural practices or complex social interactions.

At the C1 level, '等于' (děngyú) is used in highly abstract, philosophical, and literary contexts. Learners explore how the word can be used to challenge definitions or create rhetorical effects. For instance, in a debate about ethics, one might say '在极端情况下，生存是否就等于正义？' (In extreme cases, does survival equal justice?). C1 students are sensitive to the stylistic weight of '等于'. They might use it in legal analysis or scientific theory to establish identities between complex variables. They also understand the historical etymology of the characters and how '等' (rank/class) informs the modern sense of 'equality'. At this level, the learner can use '等于' to navigate high-level discussions about policy, philosophy, and linguistics, using the word to create clear, logical structures in long-form writing and speech.

At the C2 level, '等于' (děngyú) is handled with the finesse of a native speaker. The learner understands the subtle psychological impact of using '等于' to frame a reality. They can use it in creative writing to create metaphors that feel like logical truths. C2 speakers are aware of the word's place in the history of Chinese mathematics and its evolution into modern vernacular. They can effortlessly switch between the mathematical, legal, and colloquial registers of the word. Furthermore, they can analyze the use of '等于' in classical texts where '等' and '于' might have functioned differently, and they can participate in deep academic discourse where the very definition of 'equivalence' (等价性) is the subject. For a C2 learner, '等于' is not just a word, but a conceptual tool used to construct and deconstruct the logic of the world.

等于 30초 만에

等于 (děngyú) is a B1-level verb primarily meaning 'to be equal to'. It is essential for math, conversions, and expressing logical or metaphorical equivalence.
It connects two nouns or verb phrases directly without needing the verb '是' (shì). It is the standard way to say 'equals' in Chinese.
Commonly used in patterns like 'A 等于 B' or 'A 不等于 B'. Adding '就' (jiù) before it adds emphasis to the logical consequence.
It is different from '平等' (social equality) and '相等' (quantitative equality). Use '等于' for results, values, and identity of meaning.

The Chinese verb 等于 (děngyú) is a foundational term that serves as the linguistic bridge between mathematical certainty and metaphorical equivalence. At its most basic level, it functions exactly like the equals sign (=) in an equation. However, as students progress to the CEFR B1 level and beyond, they discover that 等于 is far more versatile than a mere arithmetic operator. It is used to express that one situation, action, or concept is effectively identical in result or significance to another. When you say 'A 等于 B,' you are asserting a fundamental identity between two entities, whether you are calculating a grocery bill or debating the moral implications of a political decision.

Mathematical Function: In classrooms and daily commerce, this word is the standard way to express 'equals'. For example, 'Two plus two equals four' is rendered as '二加二等于四'. It is used for addition, subtraction, multiplication, and division results, providing a definitive statement of value.
Metaphorical Equivalence: Outside of math, it links an action to a consequence. Saying 'Doing this is equal to giving up' uses 等于 to show that the two ideas are inseparable in their outcome. It adds a layer of weight and finality to a statement.
Logical Identity: In formal logic and legal contexts, it defines terms. If a contract states that 'Breach of clause A equals termination,' 等于 is the operative verb that establishes this legal reality.

如果你不努力，就等于在浪费生命。(If you don't work hard, it's equivalent to wasting your life.)

The word is composed of two characters: 等 (děng), which can mean 'class', 'rank', or 'wait', but here carries the meaning of 'equal' or 'same'; and 于 (yú), a preposition often meaning 'to', 'at', or 'than'. Together, they literally mean 'to be equal to'. This structure is very common in formal Chinese verbs that take an object directly after '于'. In daily conversation, you will hear people use it to simplify complex situations. If a friend asks if they should buy a cheap but broken car, you might say, '买它就等于买麻烦' (Buying it equals buying trouble). It is a powerful tool for reductionism—taking a complex set of circumstances and boiling them down to a single, comparable noun or phrase.

三乘以三等于九。(Three times three equals nine.)

Using 等于 (děngyú) correctly requires understanding its role as a transitive verb that links two entities of comparable grammatical weight. Whether you are dealing with numbers, nouns, or entire verb phrases, the structure remains consistent: [Subject] + 等于 + [Object]. Unlike some other verbs, it rarely takes aspect markers like '了' (le) or '过' (guo) because equality is generally treated as a constant state or a logical fact rather than a completed action.

The Mathematical Pattern: The most rigid use is in arithmetic. The pattern is [Number/Equation] + 等于 + [Result]. For example: '十减七等于三' (10 - 7 = 3). In this context, it is irreplaceable and formal.
The 'Action as Equivalence' Pattern: This is common in B1 level speech. [Verb Phrase A] + 等于 + [Verb Phrase B/Noun]. For instance, '天天加班等于没有生活' (Working overtime every day equals having no life). Here, the speaker is equating a lifestyle with a specific outcome.
The Negative Form: To say something 'does not equal', simply place '不' (bù) before the verb: [A] + 不等于 + [B]. Example: '有钱不等于快乐' (Having money does not equal happiness). This is a very common rhetorical device in Chinese to debunk myths or clarify misunderstandings.

你的沉默就等于承认了错误。(Your silence is equivalent to admitting the mistake.)

One nuance to watch for is the use of the adverb '就' (jiù) before 等于. Adding '就' adds emphasis, making the equivalence feel more immediate or certain. It is often translated as 'is basically' or 'is as good as'. For example, '你不去就等于放弃机会' (If you don't go, it's basically giving up the opportunity). Without '就', the sentence is a plain statement of fact; with '就', it carries a tone of warning or logical consequence. Another important aspect is the object. While English often uses adjectives after 'equals' (e.g., 'This equals bad'), Chinese almost always uses a noun or a verb phrase. Instead of saying '这等于坏' (incorrect), you would say '这等于一件坏事' (This equals a bad thing).

一百公分等于一公尺。(One hundred centimeters equals one meter.)

In the real world, 等于 (děngyú) appears in a wide array of settings, from the mundane to the highly philosophical. If you walk into a primary school in Beijing, you will hear children chanting multiplication tables: '三三得九' (three threes get nine), but when they write it out or speak formally, they use 等于. In a business meeting at a tech firm in Shanghai, you might hear a manager say, '失去这个客户就等于失去今年的奖金' (Losing this client equals losing this year's bonus). Here, it is used to motivate or stress the gravity of a situation.

News and Media: Newscasters often use it to explain complex statistics or economic shifts. '通货膨胀等于购买力下降' (Inflation equals a decrease in purchasing power). It serves to simplify economic jargon for the general public.
Legal and Official Documents: In contracts, '等于' is used to define equivalents in currency or measurements. '逾期未付等于违约' (Failure to pay on time equals a breach of contract). It provides the legal 'if-then' clarity required in professional life.
Social Media and Slang: On platforms like Weibo or Douyin, you'll see memes using the 'A = B' format to make humorous or cynical points. '周五晚上等于自由' (Friday night equals freedom). It is a shorthand for expressing strong feelings or shared cultural sentiments.

在这个行业，时间就等于金钱。(In this industry, time equals money.)

Another common place is in scientific discourse. If you are reading a Chinese research paper or watching a science documentary, 等于 is the standard term for physical constants and formulas. For example, '质量乘以速度等于动量' (Mass times velocity equals momentum). It bridges the gap between the abstract mathematical world and physical reality. Even in casual relationships, people use it to set boundaries or expectations. A partner might say, '你骗我就等于不爱我' (You lying to me equals you not loving me). This emotional use of 等于 shows how deeply the concept of 'equivalence' is baked into the way Chinese speakers process logic and morality.

没带钥匙等于进不去家门。(Not bringing keys equals not being able to enter the house.)

While 等于 (děngyú) seems straightforward because of its English counterpart 'equals', there are several pitfalls that learners frequently encounter. These mistakes usually stem from direct translation from English or a misunderstanding of Chinese verb-object structures. Addressing these early will make your Chinese sound significantly more natural and precise.

Adding '是' (shì): The most common error is saying '是等于' (shì děngyú). In English, we say 'is equal to', where 'equal' acts like an adjective. In Chinese, '等于' is a full verb. You don't need '是'. Wrong: '一加一是等于二'. Right: '一加一等于二'.
Using Adjectives as Objects: Learners often try to equate something to an adjective. '这样做等于累' (Doing this equals tired). This is grammatically awkward. You should equate it to a noun phrase or a verb phrase. Better: '这样做等于自找麻烦' (Doing this equals looking for trouble).
Confusing with '相等' (xiāngděng): '相等' means 'to be equal' but it is an intransitive verb or an adjective used to describe two subjects. You say 'A 和 B 相等' (A and B are equal). You cannot say 'A 相等 B'. Conversely, '等于' must have an object: 'A 等于 B'.

错误：他的话是等于废话。
正确：他的话等于废话。(His words are equivalent to nonsense.)

Another mistake involves the scope of '等于'. It is strictly for equivalence of value, identity, or result. It is not used for 'equal' in terms of social rights or status in the same way '平等' (píngděng) is. If you want to say 'Men and women are equal,' you must use '男女平等', not '男等于女'. The latter would imply they are the exact same thing or person, which is logically incorrect in that context. Furthermore, avoid using '等于' when you simply mean 'is'. If you say '他是等于老师', it sounds like he is a fake teacher or a substitute for a teacher. If he is actually a teacher, just use '他是老师'.

不要说：二加二是等于四。(Don't say: 2+2 'is' equals 4.)

In Chinese, several words share the semantic space of 'equality' and 'equivalence'. Choosing the right one depends on whether you are talking about math, social justice, comparisons, or logical identity. Understanding these nuances is key to reaching a B1 level and beyond.

相当于 (xiāngdāngyú): This means 'equivalent to' or 'corresponds to'. It is used when two things are not identical but have the same value or effect. For example, '十美元相当于七十人民币' (10 USD is equivalent to 70 RMB). Use this for exchange rates or comparing different systems.
平等 (píngděng): This is an adjective/noun referring to social or legal equality. '人人平等' (Everyone is equal). It does not take an object like '等于'. You cannot '平等' something; you 'are' equal in status.
相等 (xiāngděng): This means 'equal' or 'identical' in quantity or size. It is usually used with '和' (and). '这两个面积相等' (These two areas are equal). It is more descriptive of a state than an active equation.
同于 (tóngyú): Literally 'same as'. It is very formal and often found in literature or academic writing. '此法同于彼法' (This method is the same as that method). It is less common in speech than '等于'.

虽然价格不同，但效果相当于是一样的。(Although the prices are different, the effect is equivalent to being the same.)

When deciding which to use, ask yourself: Am I solving a math problem? (Use 等于). Am I saying two things are basically the same in result? (Use 等于 or 相当于). Am I talking about human rights? (Use 平等). Am I comparing two physical properties like length or weight? (Use 相等). For learners, '等于' is the safest bet for 'equals', while '相当于' is better for 'is like' or 'is equivalent to' when comparing things from different categories. Using '跟...一样' (gēn... yíyàng) is the most common way to say 'same as' in casual conversation for physical objects, like 'My phone is the same as yours'.

法律面前，人人平等。(Before the law, everyone is equal.)

How Formal Is It?

어원

The character 等 (děng) originally depicted bamboo slips (竹) used for keeping records or ranks, combined with 寺 (sì) which acted as a phonetic component and also suggested order or law. 于 (yú) is an ancient preposition indicating direction or relation. Combined, they mean 'to be in the same rank as' or 'to relate as an equal'.

원래 의미: Originally, '等' meant a rank or a class of people. By the Han Dynasty, it evolved to mean 'to be same as' or 'to compare'.

Sino-Tibetan, specifically Sinitic.

문화적 맥락

Be careful when equating people or groups using '等于', as it can sound reductionist or dehumanizing if used incorrectly.

English speakers often say 'is' instead of 'equals'. In Chinese, using '等于' makes the statement feel more like a logical proof or an undeniable fact.

The mathematical expression '1+1=2' is universally recognized in China as '一加一等于二'. Political slogans often use '不等于' to clarify policies. The phrase '沉默等于承认' is a common trope in Chinese TV dramas.

자주 묻는 질문

10 질문

Generally, no. For social equality, use '平等' (píngděng). If you say 'A 等于 B' about people, it sounds like you are saying they are the same person or have the exact same numeric value, which is rare.

No, it is very common in daily life to show that one action is the same as another in result. For example, '你不去等于放弃' (You not going equals giving up).

'是' is a general 'is'. '等于' is more specific, meaning 'equals in value'. You can say 'He is a teacher' (他是老师), but you wouldn't say 'He equals a teacher' (他等于老师) unless you are in a very strange context.

You use '约等于' (yuē děngyú). For example, '10除以3约等于3.33'.

No, it is always a verb. The noun for 'equality' is '平等' or '等同'.

It is neutral. It is used in both casual conversation and formal scientific papers.

Usually no. Equality is a state, so aspect markers like '了' are rarely needed unless you are talking about a value that has just become equal in a specific process.

No. You must say 'A 等于 B' or 'A 和 B 相等'.

Use '不等于' (bù děngyú). It's very common in rhetorical speech.

Yes, but '相当于' (xiāngdāngyú) is more common for exchange rates because the currencies are different entities with the same value.
