If you’re starting French, you might need to learn French numbers from 1 to 20 and French numbers from 1 to 100.


Why are big numbers so weird in French?


Numbers in French can seem weird for foreigners, especially for English-speaking ones.

Big numbers are kind of special too. What we mean by big numbers or large French numbers are numbers over three digits.

Writing big numbers or understanding written big numbers in French requires to know some basic rules.

First, French people don’t use a comma to point out thousands or millions:

♦ The comma is used in writing a number with a decimal part, to separate the whole number part from the fractional part. There is no such thing as a decimal point in French.

♦ The dot is sometimes used to separate numbers into 3-digit increments. However, it’s rare and this is not really recommended by the typographic code. It is far better to leave spaces to point out thousands, millions and so on.



How to write big numbers in French


Hundreds in French


First, one hundred is written cent. Please notice that French people don’t use any determiner or any numeral adjective before “cent“.

Thus, you get :

100 : cent

200 : deux cents

300 : trois cents

400 : quatre cents

500 : cinq cents

600 : six cents

700 : sept cents

800 : huit cents

900 : neuf cents

As you can see, the multiples of cent take a final s.

However, cent doesn’t have any final s when it’s followed by another numeral adjective. For example, 320 is written “trois cent vingt”.

This rule doesn’t apply when “cent” is used before “millions” and you have to write : “deux cents millions”.

To tell the numbers after the hudreds, you just have to add the tens or so:

101 = cent-un

102 = cent-deux

110 = cent-dix

123 = cent-vingt-trois

Thousands in French


The word for one thousand in French is mille. The logic is the same as one hundred and cent : French people don’t use any designator for one.

1 000 = mille

2 000 = deux mille

3 000 = trois mille

4 000 = quatre mille

5 000 = cinq mille

6 000 = six mille

7 000 = sept mille

8 000 = huit mille

9 000 = neuf mille

10 000 = dix mille

11 000 = onze mille

and so on…

For hundreds of thousands, you say:

100 000 = cent mille

101 000 = cent un mille

110 000 = cent dix mille


Things to know:

♦ Mille never takes any final s. It’s invariable.

You can add hyphens between each numbers since the 1990 spelling reform.



What about millions and milliards in French?


♦ Million and milliard take an s when they are used in the plural form.

♦ Their logic of use is the same as for thousands, except for one million and one milliard that get a determiner or a numeral adjective.

1 000 000 = un million

2 000 000 = deux millions

10 000 000 = dix millions

11 000 000 = onze millions

100 000 000 = cent millions

and so on…
