Measurements in Spanish

Quick Answer

Ever wonder how Spanish-speakers talk about inches, pounds, liters, and gallons? They usually don’t.

That’s because most countries outside the United States use el sistema métrico decimal, called the metric system in English, to measure everything from distance, volume, and temperature.

In this article, we’ll give you a brief introduction to the metric system as well as show you how to use those terms in Spanish. And don’t worry—we’ll also give you the Spanish translations for all of las medidas, or measurements, used in the U.S. too, just in case you need them.

Talking About Length and Distance

Understanding the metric system is easy when you understand that the different measurements used for calculating length or distance are all divisible by 100. For example, there are one hundred centímetros, centimeters in English, in un metro, or a meter. For calculating units of length or distance larger than one meter, we also follow this pattern. Un kilómetro, one kilometer, is the same thing as a thousand meters. Check out the tables below for the translations of the metric measurements, their American counterparts, and conversions for both.

That’s a lot of measurements! Here are a couple examples to help you make sense of them.

Desde aquí hasta el aeropuerto son unos 20 kilómetros.
It’s about 20 kilometers from here to the airport.
¿Cuántas yardas se extiende una cancha de fútbol americano?
How many yards long is a football field?

Talking About Weight and Fluid Volume

Spanish-speakers not only use the metric system for measuring length and distance, but also to calculate el peso y el volumen de líquidos, or the weight and fluid volume, of objects as well! Feel free to use these measurements when talking about the amount of water in a bottle or how heavy a package is. Check out the lists below to learn the translations of the metric measurements for weight and fluid volume, their American counterparts, and conversions for both.

That’s un montón de información(a ton of information)! Here are a couple of examples to make sure you can use these measurements in action.

El doctor recomienda que tome dos litros de agua todos los días.
The doctor recommends that I drink two liters of water a day.
Bajo mi nuevo régimen de dieta y ejercicio, perdí diez libras en un solo mes.
Under my new regimen of diet and exercise, I lost ten pounds in just one month.

You might have noticed that our translation above for a ton of information was not una tonelada de información, but un montón de información. In Spanish, you can only use tonelada when referring to something’s physical weight. If you want to use ton as an intensifier in order to talk about how much of something there is, be sure to use the Spanish word montóninstead.


Hubo un montón de gente en el concierto.
There were a ton of people at the concert.

Talking About Temperature

In the United States, we use a system of measurement to talk about temperature called the Fahrenheit scale, where units of temperature are expressed in grados Fahrenheit, or degrees Fahrenheit in English. In the Spanish-speaking world (and the rest of the world), the Celsius scale is used. In the Celsius scale, units of temperature are expressed in grados centígrados, or degrees celsius in English. Check out the table below for the translations, freezing points, and boiling points of these two scales.
