At the A1 level, 'un kilo' is one of the first quantity words you learn. It is essential for basic survival tasks like grocery shopping. At this stage, you should focus on the simple phrase 'un kilo de...' followed by common food items like 'pommes', 'sucre', or 'farine'. You will encounter it primarily in dialogues set at a market or a supermarket. The goal is to be able to ask for a specific amount of something and understand the price when it is given 'au kilo'. You don't need to worry about the scientific history or complex idioms yet; just focus on the masculine gender 'un' and the mandatory 'de'. You should also learn the abbreviation 'kg' which you will see on all labels. Practice saying 'Un kilo, s'il vous plaît' until it feels natural. This is a foundational building block for all future discussions involving measurements and quantities in French speaking environments.
At the A2 level, you expand your use of 'un kilo' to include recipes and personal health. You should be able to follow simple instructions that require weighing ingredients, such as 'Prenez un kilo de farine et mélangez-le avec de l'eau'. You also start using the verb 'peser' (to weigh) in conjunction with 'kilo'. For example, 'Ce colis pèse deux kilos'. You will learn to discuss body weight in a basic way, using phrases like 'J'ai perdu un kilo' or 'Je veux perdre trois kilos'. At this level, you should also be comfortable using 'un kilo' with the pronoun 'en', as in 'J'en voudrais un kilo' (I would like a kilo of it), which is a key step in developing more natural-sounding French. You are also expected to distinguish between 'un kilo' and 'une livre' (500g) when shopping at a traditional market, as this shows a better grasp of French cultural norms.
At the B1 level, you use 'un kilo' in more varied and abstract contexts. You can discuss environmental issues, such as the amount of waste produced per person ('chaque Français produit des centaines de kilos de déchets par an'). You can also handle more complex shopping situations, such as asking for 'un kilo et demi' (a kilo and a half) or 'environ un kilo' (about a kilo). Your understanding of the grammar should be solid, never making the mistake of saying 'un kilo des'. You might also start to encounter the word in news reports about logistics, trade, or crime (seizures of illicit goods). At this level, you should be able to explain the difference between the metric system and the imperial system in simple terms, using 'un kilo' as your primary reference point for weight. You are also more aware of the register, knowing that 'kilo' is the standard spoken word while 'kilogramme' is used in writing and formal reports.
At the B2 level, 'un kilo' is used with total spontaneity and grammatical accuracy. You can participate in debates about health and nutrition, discussing 'le prix au kilo' of organic vs. non-organic food and the socio-economic implications. You understand more nuanced expressions like 'à quelques kilos près' (give or take a few kilos). You can follow technical instructions in a workplace setting, such as in a warehouse or a laboratory, where precise measurements are vital. Your vocabulary around the word is broader, including related terms like 'le lest' (ballast/weight) or 'le surpoids' (overweight). You are also able to use 'un kilo' in more figurative or hyperbolic ways to emphasize weight or burden, though French often prefers 'une tonne' for this. You can read articles about the history of the metric system and the recent scientific redefinition of the kilogram based on physical constants without major difficulty.
At the C1 level, you have a sophisticated grasp of 'un kilo' and its place in the French language. You can appreciate the stylistic choice between 'kilo' and 'kilogramme' in literature or high-level journalism. You understand the historical and cultural significance of the metric system as a product of the French Enlightenment and can discuss how it standardized trade across Europe. You are familiar with idiomatic expressions and can use the word in complex sentence structures involving subjunctions or sophisticated pronouns. You can also handle technical or scientific discussions where 'le kilo' is the unit of measure for energy equivalents or other advanced physics concepts. At this level, your pronunciation is flawless, capturing the subtle 'closed o' and the correct rhythm of the word within a sentence. You can also recognize regional variations or older terms that might still pop up in literature, such as the 'once' or 'denier', and explain them in relation to the modern kilo.
At the C2 level, 'un kilo' is a transparent element of your near-native fluency. You can engage in academic discussions about the metrology and the philosophical implications of universal standards. You can analyze the use of weight-based metaphors in French poetry or prose. You are comfortable in any professional environment, from a high-tech manufacturing plant to a gourmet kitchen, where 'un kilo' might be the difference between success and failure. You understand the most obscure uses of the word, including its role in various dialects of the Francophone world. You can write persuasive essays on the benefits of the metric system or the psychological impact of weight measurements in modern society. For you, 'un kilo' is not just a vocabulary word; it is a precisely calibrated tool that you use with the same ease and nuance as a native speaker, reflecting a deep integration into the French linguistic and cultural identity.

un kilo 30초 만에

  • Un kilo is the standard French unit for weight, equal to 1,000 grams or about 2.2 pounds.
  • It is a masculine noun and always requires 'de' before the substance being measured (e.g., un kilo de sucre).
  • In informal French, 'une livre' is often used to mean exactly 500 grams or half a kilo.
  • The word 'kilo' is the everyday shorthand for the more formal and scientific term 'kilogramme'.

The term un kilo is the ubiquitous shorthand for un kilogramme. In the French linguistic landscape, it represents the standard unit of mass in the International System of Units (SI). While its scientific definition has evolved—from the weight of a liter of water to a physical platinum-iridium cylinder kept in Sèvres, and finally to a calculation based on the Planck constant—its daily usage remains grounded in the sensory experience of shopping and living. For an English speaker, un kilo is approximately 2.2 pounds. It is a masculine noun, and its gender is crucial because using the feminine article would be a noticeable grammatical error. In France and other Francophone countries, the metric system is not just a secondary measurement but the very fabric of commercial exchange. When you walk into a boulangerie, boucherie, or a marché en plein air, you will hear this word constantly. It is the baseline for purchasing everything from flour and sugar to potatoes and beef. The word is used both as a precise measurement and as a general indicator of weight. For example, if someone says they have 'quelques kilos à perdre' (a few kilos to lose), they are discussing their health and fitness goals. The abbreviation 'kilo' is so deeply ingrained that 'kilogramme' now sounds overly formal or purely academic in most casual conversations.

Masculine Noun (Nom masculin)
Quantity Structure
Always followed by 'de' (or d') when specifying the substance: 'un kilo de sucre'.

Historically, the introduction of the kilo was a revolutionary act. Before the French Revolution, France suffered from a chaotic system of regional measurements that varied from town to town, often leading to fraud and confusion. The 'kilogramme' was established in 1795 as part of a move toward logic and equality. Today, when a French person asks for un kilo, they are participating in a legacy of Enlightenment-era standardization. It is also worth noting that in informal speech, you might hear the plural 'kilos' used to refer to 'kilomètres' in specific contexts like cycling or driving (e.g., 'il reste dix kilos'), though this is strictly colloquial and can be confusing for learners. Generally, stick to weight. You will also encounter 'le kilo' when looking at price tags, where 'au kilo' means 'per kilogram'. This is essential for comparing values at the supermarket. Whether you are following a recipe for ratatouille or weighing your luggage at Charles de Gaulle airport, un kilo is the fundamental unit you must master.

S'il vous plaît, je voudrais un kilo de tomates bien mûres pour ma sauce.

Using un kilo correctly in a sentence requires an understanding of French quantity syntax. The most important rule is the 'de' rule. In English, we say 'a kilo of apples'. In French, it is un kilo de pommes. Note that even if 'pommes' is plural, the word 'de' does not change to 'des'. This is a common pitfall for English speakers who are used to the partitive articles (du, de la, des). Whenever a specific quantity is mentioned—like a kilo, a liter, or a gram—the article disappears, and you are left with the preposition 'de'. If the following word starts with a vowel, 'de' elides into d', as in un kilo d'abricots (a kilo of apricots). This structure is rigid and applies across all levels of formality. When you are at a market stall, you might simply say, 'J'en prendrai un kilo' (I'll take a kilo of them), where the pronoun 'en' replaces the noun phrase 'de [thing]'.

Standard Pattern
[Number] + kilo(s) + de + [Noun]
Price Pattern
[Price] + le kilo (e.g., 'Cinq euros le kilo')

Another common usage is related to body weight. In French, you don't 'weigh' a certain amount in the same way English speakers use the verb. While you can say 'Je pèse soixante kilos', it is very common to talk about gaining or losing weight using 'prendre' or 'perdre'. For example, 'J'ai pris deux kilos pendant les fêtes' means 'I gained two kilos during the holidays'. Conversely, 'Elle a perdu un kilo' means 'She lost a kilo'. When discussing measurements in recipes, precision is key. While many French recipes use grams for smaller amounts, un kilo is the standard for bulk ingredients like flour in bread making or fruit for preserves. In scientific or highly technical contexts, you should revert to the full word kilogramme to ensure there is no ambiguity, although in a lab, 'un kilo' is still understood perfectly.

Ce sac de farine pèse exactement un kilo, c'est parfait pour notre recette de pain.

Les pommes de terre sont à deux euros le kilo aujourd'hui au marché.

To hear un kilo in its natural habitat, one must visit the local French markets. These markets, which take place once or twice a week in almost every French village and city neighborhood, are the epicenter of the word's usage. You will hear vendors shouting prices: 'Un kilo pour le prix d'un demi !' (A kilo for the price of a half!). Customers will lean over stalls and ask, 'Donnez-moi un kilo de ces pêches, s'il vous plaît' (Give me a kilo of those peaches, please). In this context, the word is often accompanied by gestures—pointing at the specific produce or the scale. It is also common to hear 'un petit kilo' or 'un bon kilo'. A 'petit kilo' implies a bit less than a kilo or just a small amount, while a 'bon kilo' suggests a generous portion, perhaps slightly over the mark. This reflects the social and somewhat flexible nature of market commerce compared to the clinical precision of a supermarket scanner.

In the domestic sphere, un kilo is a frequent guest in French kitchens. French culture places a high value on cooking from scratch, and most staples are sold in one-kilo bags. Sugar, flour, salt, and rice are almost always packaged this way. If you are watching a French cooking show or following a YouTube tutorial by a French chef, you will hear measurements like 'ajoutez un kilo de farine'. Beyond the kitchen, you will encounter the word in health-related discussions. The French are often conscious of their 'ligne' (figure), and conversations about 'perdre quelques kilos' are common in magazines, gyms, and social gatherings. In the news, you might hear about 'un kilo de drogue' being seized, as journalists use the term for illicit substances. Finally, at the airport, the check-in agent will tell you if your suitcase is 'un kilo trop lourd' (a kilo too heavy), a phrase every traveler fears.

Au marché, le vendeur m'a dit : « C'est trois euros le kilo, ma petite dame ! »

Context: Supermarket
Checking the weight of pre-packaged meat or weighing vegetables at the digital scale station.
Context: Fitness
Discussing weightlifting goals or weight loss progress with a trainer.

The most frequent mistake English speakers make with un kilo is related to the gender of the noun. Because many words ending in 'o' in other Romance languages might be masculine, English speakers often guess correctly, but there is a tendency to accidentally use the feminine 'une' if they confuse it with other measurement words like 'une livre' (a pound) or 'une tonne' (a ton). Always remember: Le kilo est masculin. Another major error is the misuse of the partitive article after the word. Learners often say 'un kilo des pommes' because they think they need to pluralize the 'de'. However, as established in French grammar, expressions of quantity are followed by a simple 'de' (or 'd' before a vowel). Saying 'un kilo des pommes' would actually mean 'a kilo of THE apples' (specific ones), which is rarely what is intended in a general shopping context.

Pronunciation also presents a small hurdle. The 'o' at the end of 'kilo' is a 'closed o' in French, similar to the sound in 'slow' but without the 'w' glide at the end. English speakers often add a diphthong, making it sound like 'kee-low-uh'. To sound more native, keep the 'o' short and clipped. Additionally, some learners confuse 'kilo' with 'kilomètre'. While 'kilo' can technically be a prefix for any unit (kilolitre, kilowatt), in isolation, it always refers to mass. If you mean distance, you must say kilomètre or use the slang borne. Conversely, don't use 'kilo' to mean 'kilometer' unless you are in a very specific cycling or racing subculture where this shorthand is occasionally used, as it will likely lead to confusion in everyday life. Finally, avoid using 'kilo' when you mean 'weighing scale'—that device is un pèse-personne (for people) or une balance (for objects).

Incorrect: J'ai acheté une kilo de sucre.
Correct: J'ai acheté un kilo de sucre.

Mistake: The 'Des' Trap
Avoid: 'Un kilo des oranges'. Use: 'Un kilo d'oranges'.
Mistake: Confusion with Scale
Don't say 'Le kilo dit que je suis gros'. Say 'La balance dit que j'ai pris du poids'.

While un kilo is the standard, there are several related terms that you should know to navigate French measurements like a pro. The most formal version is un kilogramme. You will see this on official documents, food packaging, and in scientific texts. For smaller amounts, un gramme (one gram) is used. There are 1,000 grams in a kilo. In recipes, you will often see '500g' or '250g'. A very common traditional alternative is une livre. Historically, a 'livre' was about 489 grams, but since the adoption of the metric system, the French have redefined 'une livre' to mean exactly 500 grams (half a kilo). If you ask for 'une livre de beurre' at a market, the vendor will give you exactly 500g. It is a very 'French' way of shopping and shows a higher level of fluency.

For larger weights, you have un quintal (100 kilos) and une tonne (1,000 kilos). 'Une tonne' is often used figuratively in French, just like in English: 'J'ai une tonne de travail' (I have a ton of work). In terms of verbs, peser is the verb meaning 'to weigh'. If you want to talk about the act of weighing something, you use le pesage or the verb peser. Another related word is la masse (mass), which is used in physics to distinguish between mass and weight (poids). In everyday life, 'poids' and 'masse' are used interchangeably, but 'poids' is much more common. If you are buying something very light, like saffron or expensive spices, you might deal in milligrammes. Understanding these increments helps you understand the scale of un kilo as the 'middle ground' of daily measurements.

Kilo vs. Livre
1 Kilo = 1000g. 1 Livre = 500g. Both are used daily in markets.
Kilo vs. Gramme
Use 'gramme' for precision (e.g., spices, jewelry). Use 'kilo' for bulk (e.g., vegetables, flour).

Je n'ai pas besoin d'un kilo entier, une demi-livre suffira largement pour cette sauce.

재미있는 사실

The kilo is the only SI base unit that includes a prefix (kilo-) in its name. This is because the 'gramme' was originally considered the base, but it was too small for practical use as a standard.
