In this volume, we discuss the alphabet, definite and indefinite articles, and verbs ser and estar, among other topics.

Are you familiar with how to discuss measurements in Spanish? Countless things in the world can be measured, spanning various categories such as physical quantities, time, information, and more. Essentially, almost anything that can be quantified or compared can be measured in some way. However, in this article, we'll be focusing on a select few units of measurement that are commonly used in everyday life and scientific contexts. 

We will also explore the differences between the metric and imperial systems used in Spanish-speaking countries and the US, respectively. To wrap things up, you'll have the opportunity to test your knowledge with a fun quiz.

Metric System vs Imperial units

The metric system and the imperial system are two distinct measurement systems. The metric system is more commonly used worldwide, including Spain and Latin America, while the imperial system is more traditional and limited to countries like the U.S., Myanmar, and Liberia. Interestingly, although the Imperial System originated in the UK and its empire in 1826, the UK has since adopted the metric system.

Let’s take a look at some common terms used to measure length, volume, weight, surface area, and temperature:

Length - Longitud 

Metric system:

  • el centímetro: centimeter
  • el kilómetro: kilometer
  • el metro: meter
  • el milímetro: millimeter

La serpiente medía aproximadamente 2 centímetros de diámetro. 

(The snake measured approximately 2 centimeters in diameter.)

Imperial System:

  • la milla: mile
  • el pie: foot
  • los pies: feet
  • la pulgada: inch
  • la yarda: yard
Fun fact! Although the Metric System is globally used, when talking about the size of a computer or TV screen, inches are normally used: 
Mi nueva televisión tiene una pantalla de 65 pulgadas. 
(My new television has a 65-inch screen.)

Surface area - Unidad de superficie

  • el acre: acre
  • el centímetro cuadrado: square centimeter
  • la hectárea: hectare
  • el kilómetro cuadrado: square kilometer
  • el metro cuadrado: square meter
  • el milímetro cuadrado: square millimeter

Mi nuevo apartamento tiene un tamaño de 70 metros cuadrados. 

(My new apartment is 70 square meters.)

Volume - Volumen

Metric System:

  • el centilitro: centiliter
  • el centímetro cúbico: cubic centimeter
  • el decímetro cúbico: cubic decimeter
  • el litro: liter
  • el metro cúbico: cubic meter
  • el mililitro: milliliter

Es importante beber al menos 2 litros de agua al día para mantenerse hidratado.

(It's important to drink at least 2 liters of water a day to stay hydrated.)

Imperial System:

  • el cuarto de galón: quart
  • la cucharada: tablespoon
  • la cucharadita: teaspoon
  • el galón: gallon
  • el pie cúbico: cubic foot
  • la pinta: pint
  • la pulgada cúbica: cubic inch
  • la yarda cúbica: cubic yard

Agregue una cucharadita de sal a la sopa para darle más sabor. 

(Add a teaspoon of salt to the soup to give it more flavor.)

Weight - Peso

Metric System:

  • el centigramo: centigram
  • el decagramo: decagram
  • el decigramo: decigram
  • el gramo: gram
  • el hectogramo: hectogram
  • el kilogramo: kilogram
  • el miligramo: milligram
  • la tonelada: ton

Para preparar arroz blanco, utiliza 200 gramos de arroz y 400 mililitros de agua.

(To prepare white rice, use 200 grams of rice and 400 milliliters of water.)

¡Ojo! Although related, masa (mass) and peso (weight) are not the same thing! Mass is the amount of matter an object contains, while weight is the force exerted on an object due to gravity.

Imperial System:

  • la libra: pound
  • la onza: ounce

El recién nacido pesó siete libras y ocho onzas.

(The newborn baby weighed 7 pounds and 8 ounces.)

Temperature - Temperatura 

  • el grado Centígrado: degree Celsius
  • el grado Fahrenheit: degree Fahrenheit

En verano, las temperaturas en España suelen ser muy altas, a menudo superando los 35 grados centígrados. 

(In summer, temperatures in Spain are usually very high, often exceeding 35 degrees Celsius.)

Fun fact! The Fahrenheit scale, proposed by Daniel Gabriel Fahrenheit in 1724, is a temperature scale using degrees Fahrenheit (°F) as the unit, with 0 °F defined as the freezing point of a brine solution and the upper limit initially set at the average human body temperature.

Other units of measurement

Let’s take a look at some other units of measurement. While some of these units might not be a part of your everyday life, it's always beneficial to have a diverse knowledge base. Let's discover some of these lesser-used units, as you never know when they could come in handy!

Electric current: Corriente eléctrica

An electric current is the flow of electricity in an electronic circuit, and the amount of electricity flowing through a circuit. It is measured in amperes (A), amperios in Spanish.

Un enchufe doméstico típico puede manejar una corriente de 15 amperios. 

(A typical domestic outlet can handle a current of 15 amperes.)

Luminous intensity - Intensidad luminosa

Luminous intensity is the amount of light a light source emits in a particular direction per unit solid angle. The candela is an SI base unit for luminous intensity. In Spanish, also called candela.

Una vela típica emite alrededor de 1 candela de luz.

(A typical candle emits about 1 candela of light.)

Fun Fact! Not only is Candela a unit of measurement for luminous intensity, but it's also a beautiful and unique name given to girls, particularly in Spanish and Italian cultures. 

Energy - Energía

The quantitative property that is transferred to a body or to a physical system is called energy. The law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J) or julio (yes, like the month!) in Spanish.

Una bicicleta que viaja a una velocidad de 10 km/h gasta aproximadamente 100 julios por segundo. 

(A bicycle traveling at a speed of 10 km/h uses about 100 joules per second.)

Pressure - Presión

Pressure is the amount of force applied per unit area. The SI unit for pressure is the pascal (Pa), equal to one newton per square meter (N/m^2). 

La presión atmosférica a nivel del mar es aproximadamente 101.325 pascales.  

(The atmospheric pressure at sea level is approximately 101,325 pascals.)
