Big numbers in Portuguese

30 de November de 2016

How’s it going? Today we will talk about big numbers in Portuguese.

Talking about Big numbers in Portuguese

First of all, if you don’t remember the other numbers in Portuguese, don’t worry. You can read about the numbers from 1 to 100 in this Dica. While we are still talking about smaller numbers, did you know that we have two ways of saying the number 6 in Portuguese?

It’s very important knowing big numbers in Portuguese when we want to talk about dates, years, and money. So, let’s start from the number 100. Take a look:

100 Cem
200 Duzentos / Duzentas
300 Trezentos / Trezentas
400 Quatrocentos / Quatrocentas
500 Quinhentos / Quinhentas
600 Seiscentos / Seiscentas
700 Setecentos / Setecentas
800 Oitocentos / Oitocentas
900 Novecentos / Novecentas
1.000 Mil
2.000 Dois mil
Um milhão
Um bilhão
Um trilhão
Very large unspecified number
Um zilhão

Notice that when we talk about the number 1.000 we don’t say um mil we only say mil. 

You probably saw that from the number 200 to 900 we have two options: a masculine form and a feminine. The form you’ll use will depend on the word you’re referring to. If it’s a feminine word, you’ll use the feminine form. Take a look:

250 cadeiras (chairs)Duzentas e cinquenta cadeiras
900 semanas (weeks)Novecentas semanas.

Cem vs. cento

In Portuguese we only use the word cem when talking about the exact number 100. If you want to say 100 + any other number, you should say: cento , + the conjunction e,  + the other number. Take a look at the examples:

101 – Cento e um

130 – Cento e trinta

199 – Cento e noventa e nove

If you can’t specify the number and want to say something like “hundreds ” you can say centenas. For example:

Eu tenho centenas de livros.
I have “hundreds” of books. 

Talking about 200, 300 and 500: the exceptions 

You’ll learn below a rule that will help you complete some numbers. But this rule doesn’t apply to the numbers 200, 300 and 500 because they are exceptions. To talk about these numbers we have to memorize the names that we learned in the table above.

Now, let me show you how we can complete these numbers with the examples 203, 364 and 528. You have to say the name of the number and then add the rest of it.

203: duzentos + três = duzentos e três

364: trezentos + sessenta e quatro = trezentos e sessenta e quatro

528: quinhentos + vinte e oito = quinhentos e vinte e oito

Numbers from 400 to 999

To say the numbers from 400 to 900 we can follow a pattern: the number + centos. This pattern will not apply to the numbers 200, 300 and 500. Take a look at the examples:

400: quatro + centos =  quatrocentos

415: quatro + centos + quinze = quatrocentos e quinze

626: seis + centos + vinte e seis = seiscentos e vinte e seis

750: sete + centos + cinquenta = setecentos e cinquenta

803: oito + centos + três = oitocentos e três

Feminine form of some numbers

As we told you before, another important thing to notice is that some numbers (from 200 to 999) can be used in the feminine form according to what you’re referring to. To talk about these numbers it’s very easy: you say the first number and then add centas (in the feminine form). For example:

600: seis + centos = seiscentas

800: 8 + centos = oitocentas

Eu contei oitocentas histórias.
I told eight hundred stories.

Ele tem seiscentas amigas.
He has six hundred friends.

As we told you before, the numbers 200, 300 and 500 don’t follow this rule. They can be used in the feminine form too, but we have to use the names we learned in the table and change the o for an a: duzentos/duzentas (200), trezentos/trezentas (300) and quinhentos/quinhentas (500).

Notice that the number 100 and the numbers bigger than 1.000 don’t have a feminine form. So we can’t say centa only cento as explained above. Let’s see more examples to make it clearer:

Tenho 1201 amigas. 
I have 1201 friends.

We would say: mil duzentas e uma amigas.  So we put the number 200 in the feminine form and also the number 01 (because number 1 and 2 have feminine forms). So if you want to say 621 amigas (female friends), for example, you should put all the numbers that you can in the feminine = seiscentas e vinte e uma amigas

When we are referring to a feminine noun, we have to put all the numbers that have a feminine form… in the feminine! Today we showed you some big numbers that have a feminine form, but of course you may need to complete these with smaller numbers, see other Dicas to make sure the numbers that have the feminine form too.

Talking about millions

Now, let’s pay attention to the really big numbers. Talking about the million category, we do like this:

1.000.000 – Um milhão

And now, we will change the first number according to what we want to say and put the word milhão in the plural form: milhões. Take a look:

4.000.000: quatro milhões

8.000.000: oito milhões

We can follow the same pattern when talking about billions and  trillions. Check out:  – Um bilhão – Dois bilhões – Um trilhão – Três trilhões

How to say complete numbers

Every time we use big numbers in Portuguese, we need to pay attention to the use of the comma and the e. We use the comma before the thousands and hundreds, and we use the e before the tens and the units. This is how we do it:

Big numbers in Portuguese example: Um milhão, mil, trezentos e quarenta e oito.

And depending on the numbers that come after, we change the number cem into cento. Let’s see some examples:

Examples with big numbers

121 – Cento e vinte e um.
237 – Duzentos e trinta e sete.
1.990 – Mil, novecentos e noventa.
4.259 – Quatro mil, duzentos e cinquenta e nove.
9.135 – Nove mil, cento e trinta e cinco.
54.033 – Cinquenta e quatro mil e trinta e três.
173.862 – Cento e setenta e três mil, oitocentos e sessenta e dois.
631.897 – Seiscentos e trinta e um mil, oitocentos e noventa e sete.
7.543.100 – Sete milhões, quinhentos e quarenta e três mil e cem.
16.550.024 – Dezesseis milhões, quinhentos e cinquenta mil e vinte e quatro.
