In case you were wondering how to say “numbers” in Spanish, it’s números. The word for “number” in Spanish is número.

So, let"s learn some números, starting with Spanish cardinal numbers!

Spanish for Numbers 1-10

Let"s start with the basics. Here are the cardinal numbers in Spanish from 1-10:

1 – uno2 – dos3 – tres4 – cuatro5 – cinco6 – seis7 – siete8 – ocho9 – nueve10 – diez

1 – 100 Spanish Numbers

Now for the Spanish numbers 1 to 100. After you"ve read these, I"ll explain some tricks for remembering them.

91 noventa y uno92 noventa y dos93 noventa y tres94 noventa y cuatro95 noventa y cinco
96 noventa y seis97 noventa y siete98 noventa y ocho99 noventa y nueve100 cien

Take a look and try to spot the patterns. I recommend you follow these steps to get all the numbers into your head:

Learn the numbers for 1-15. There"s no real pattern, you just have to learn them: uno, dos, tres, cuatro, cinco, seis, siete, ocho, nueve, diez, once, doce, trece, catorce, quince. Learn the numbers for the multiples of ten: veinte, treinta, cuarenta, cincuenta, sesenta, setenta, ochenta, noventa. A few tips to help you remember: • Other than veinte, they all end in -enta • Other than veinte (again), they all have a clear relationship with the related smaller number: cuatro cuarenta, ocho ochenta, etc.

Then, you can fill in the gaps with a simple formula:

For numbers from 16-19, take the rightmost digit and say “diez + y + (digit)”. E.g. 17 = “diez + y + siete” = “diez y siete”, which contracts to diecisiete. This is much like how in English 16 is “six-ten” i.e. “sixteen”.For numbers above twenty, simply take the “tens” number (veinte, treinta, etc.) and the “ones” number (uno, dos, etc.) and stick y (“and”) in the middle. E.g. 31 = “thirty and one” = treinta y uno.The only extra thing to be aware of is that numbers from 21-29 get contracted into a single word – so instead of “veinte y cuatro”, it"s “veinticuatro”.

Finally, don’t forget:

zero – cero (this one should be easy to remember!)100 – cien (note the link with English words like “century” or “percent“.)

Counting Spanish Numbers 1 – 1000+

For numbers from 100 to 199, use ciento:

101 – ciento uno129 – ciento veintinueve195 – ciento noventa y cinco

(Note that you don"t need to add y after ciento – it"s ciento uno, not ciento y uno.)

For numbers from 200 to 999, you must first learn the multiples of 100.

200 – doscientos300 – trescientos400 – cuatrocientos500 – quinientos600 – seiscientos700 – setecientos800 – ochocientos900 – novecientos

These numbers have masculine and feminine forms, and so they must agree with the noun:

setecientas personas – “seven hundred people”ochocientos libros = “eight hundred books”

The only two new words you need to learn are mil (1,000) and un millón (1,000,000).

Note: 1,000 is mil, not un mil. For un millón, you can"t leave out the un.

The only time you"ll see un mil is in numbers like cuarenta y un mil (41,000). You need to put an un in this number to distinguish it from cuarenta mil (40,000).

Forming new numbers with mil and un millón is pretty straightforward as well:

1,000 – mil1,001 – mil uno (not “mil y uno”!)1,686 – mil seiscientos ochenta y seis2,001 – dos mil uno20,000 – veinte mil100,000 – cien mil483,382 – cuatrocientos ochenta y tres mil trescientos ochenta y dos1,000,000 – un millón6,492,000 – seis millones cuatrocientos noventa y dos mil

Finally, note that when you"re using un millón or millones with a noun, you must use de. For example, “one million books” is un millón de libros. Literally, “one million of books”.

Billions and Trillions in Spanish (They’re Not What You Think)

What do you think the Spanish words billón and trillón mean? Did you guess “billion” and “trillion”? Sadly, things aren"t that simple.

In the English-speaking world, a “billion” is one thousand millions (1,000,000,000) and a “trillion” is one thousand billions (1,000,000,000,000). In other words, every “step up” involves multiplying by 1,000.

Not everyone does it like this! Our way is called the “short scale” numbering system. But many countries around the world – including most Spanish-speaking countries – use the “long scale” system.

In this system, a “billion” is one million millions, and a “trillion” is one million billions. Rather than multiplying by a thousand each time, you multiply by a million.

So Spanish words like billón don"t “match up” with their English counterparts like you might expect:

un millón – one million = 1,000,000un millardo (or “mil millones”) – one billion = 1,000,000,000un billón – one trillion = 1,000,000,000,000mil billones – one quadrillion = 1,000,000,000,000,000un trillón – one quintillion = 1,000,000,000,000,000,000

(By the way, in the past, American English used the short-scale system while British English used the long-scale system. This is no longer true – all dialects of English now use the short-scale system.)

How Do You Pronounce Spanish Numbers?

So how do you say Spanish numbers? If you have trouble pronouncing the words, then take a listen to this video:

Spanish for “One”: Un, Uno, or Una?

Spanish doesn"t distinguish between “one” and “a” in the same way that English does. Un libro can mean “a book” or “one book”.

When you think about it, those two phrases mean the same thing; the only difference is in emphasis.

But the word uno changes to match the gender of the noun it describes. Before a feminine noun, it becomes una. Before a masculine noun, you drop the o and just use un.

Some examples:

Un libro – “a book/one book”. Drop the “o” from uno because it"s followed by a masculine noun.Una mesa – “a table/one table”. Change uno to una because it"s followed by a feminine noun.Tengo uno – “I have one”. Uno is unchanged because it"s not followed by a noun.“¿Hay preguntas?” “Solo una.” – “Any questions?” “Only one”. In this case, you use una because you"re referring to a pregunta (“question”), which is a feminine word.

Spanish for 100: Cien or Ciento?

The number 100 can be translated into Spanish as either cien or ciento. What"s the difference?

You should use cien when you have exactly one hundred of something:

Cien personas – one hundred peopleCien libros – one hundred books

Use ciento as part of a larger number, like ciento uno for “one hundred and one”.

Breaking Up Spanish Numbers: Dots or Commas?

In English, it"s conventional to break up big numbers with a comma every three digits to aid readability. So instead of writing “1048710123901”, we write “1,048,710,123,901”.

We also mark the decimal point with a dot, so “one half” is “0.5”.

Be careful! In Spanish-speaking countries – as in many other parts of the world – these conventions are reversed. They use a comma for decimals and break up large numbers with dots. Or, they put a space between every three digits.

So my two examples above would be written as “1.048.710.123.901” (or “1 048 710 123 901”) and “0,5”.

How to Say “…and a Half” in Spanish

In English, we often abbreviate the names of numbers by saying “… and a half”, “… and a third”, and so on.

So instead of saying “two thousand five hundred”, an English speaker might say “two and a half thousand”. Instead of “one million five hundred thousand”, they might say “one and a half million”.

I often notice Spanish people getting this wrong when they speak English. They put the “and a half” in the wrong place – instead of saying (for example) “one and a half million”, they say “one million and a half”. That"s because they"re translating directly from how they"d say in Spanish – un millón y medio.

Try not to make the opposite mistake when you speak Spanish. Say un millón y medio, not un y medio millón.
