The numbers in Spanish

Spanish lesson 4. The numbers

Hello there! In the previous Spanish lessons, we learned how to describe places, how to talk about the personality of other people and how to physically describe them.
Learning how to count may be a simple task, yet we can’t forget how important it is for everyday life and activities! Also, by learning the numbers, we will be able to deal with banks and money the most appropriate way, go check out our Survival Guide: banks and money to know more about this!

Let’s start by taking a look at this infographic we have prepared for you!

Bear in mind that the number one (1) in all its ways (1,21,31,41) changes depending on the gender of the word coming after.

¿Cuántos hijos tiene? ¿Cuántos hijos tiene?
Tengo dos hijos, un niño y una niña Tengo uno

Some interesting facts:

Talking about measurement units: one billion in an Anglo-Saxon country such as the USA is not the same as one billion in Spanish-speaking countries. On mainland Europe, Spanish and Portuguese-speaking countries (except Brazil), one billion is equal to one million millions. Meanwhile, in English-speaking countries and Brazil, one billion is equal to one thousand millions.

The numbers

Mainland Europe, Spanish and Portuguese-speaking countries English-speaking countries and Brazil
1 billion 1.000.000.000.000 (one million of millions) 1.000.000.000 (one thousand of millions)

Also, the measuring system used in the USA differs from the one used in almost everywhere else in the world. The system used in the USA is called the United States Customary Units whereas we use the International System of Units. What’s the difference between them?

The International System of Units was implemented in 1960 to unify all the different systems into one so every country would have the same measuring references. On the contrary, the United States Customary Units takes as reference the traditional measuring system used in the antique Rome.

Let’s take a brief look at this table:
