Large numbers in French, including vocabulary from thousands to trillions and examples for using and understanding big numerical values in context.

Understanding large numbers in French requires special vocabulary for thousands, millions, billions, and beyond. French uses a logical system for naming big numbers, but there are some important details to know—like how "milliard" means billion (not million) and how "billion" in French is actually a trillion in English. This guide will walk you through the essential large number words and how to use them all.

Thousands

In French, the word for "thousand" is mille, and unlike other numbers, it does not take an "s" in the plural form. You simply write mille for both 1,000 and multiple thousands (e.g., 2,000 = deux mille). When counting thousands, just put the number before mille.
French (sing./pl.)English (sing./pl.)French ExampleEnglish Example
millethousandJ’ai mille euros.I have one thousand euros.
deux milletwo thousandIl y a deux mille personnes.There are two thousand people.
dix milleten thousandElle a gagné dix mille dollars.She won ten thousand dollars.
vingt milletwenty thousandVingt mille étudiants sont inscrits.Twenty thousand students are enrolled.
cinquante millefifty thousandL’usine produit cinquante mille unités.The factory produces fifty thousand units.

Il y a ____ personnes dans la salle.


How do you say 'two thousand' in French?


deux mille
'Deux mille' means 'two thousand' in French. You simply place the number before 'mille' without changing 'mille'.

Millions

The word for "million" is million and, unlike mille, it is a noun that agrees in the plural (millions). Always use de after "million" when specifying a quantity (e.g., un million de personnes).

trois cent millionsthree hundred millionTrois cent millions d’arbres ont été plantés.Three hundred million trees have been planted.

Milliards

Milliard is the French word for billion (1,000,000,000). Like million, it is a noun that takes an "s" in the plural (milliards) and is followed by de when specifying quantities.
French (sing./pl.)English (sing./pl.)French ExampleEnglish Example

cent milliardsone hundred billionCent milliards d’actions sont en circulation.One hundred billion shares are in circulation.

Billions and Beyond

In French, billion means trillion (1,000,000,000,000). French uses a long scale system, so after milliard comes billion (trillion in English), billiard (quadrillion), and so on, but these larger terms are rarely used outside scientific or financial contexts.
French (sing./pl.)English (sing./pl.)French ExampleEnglish Example
