How to Use the Metric System in Spanish

How to Use the Metric System in Spanish You may speak Spanish well, but if youre talking to typical Spaniards or Latin Americans using inches, cups, miles, and gallons, chances are they wont understand you well even if they know words such as pulgadas and millas. With a few exceptions- among ​them, Spanish speakers inside the United States- Spanish speakers throughout the world use the metric system of measurements in everyday life. Although local or indigenous measurements are in use in some places, and American/British measurements are occasionally used for some specific instances (gasoline is sold by the gallon in some parts of Latin America, for example), the metric system is universally understood in the Spanish-speaking world. The metric system has widespread usage even in Puerto Rico, even though it is a U.S. territory. British Measurements and Their Metric Equivalents in Spanish Here are the most common British measurements and their metric equivalents in Spanish and English: Length (Longitud) 1 centimeter (centà ­metro) 0.3937 inches (pulgadas)1 inch (pulgada) 2.54 centimeters (centà ­metros)1 foot (pie) 30.48 centimeters (centà ­metros)1 foot (pie) 0.3048 meters (metros)1 yard (yarda) 0.9144 meters (metros)1 meter (metro) 1.093613 yards (yardas)1 kilometer (kilà ³metro) 0.621 miles (millas)1 mile (milla) 1.609344 kilometers (kilà ³metros) Weight (Peso) 1 gram (gramo) 0.353 ounces (onzas)1 ounce (onza) 28.35 grams (gramos)1 pound (libra) 453.6 grams (gramos)1 pound (libra) 0.4563 kilograms (kilogramos)1 kilogram (kilogramo) 2.2046 pounds (libras)1 American ton (tonelada americana) 0.907 metric tons (toneladas mà ©tricas)1 metric ton (tonelada mà ©trica) 1.1 metric tons (toneladas mà ©tricas) Volume/capacity (volumen/capacidad) 1 milliliter (mililitro) 0.034 fluid ounces (onzas fluidas)1 milliliter (mililitro) 0.2 teaspoons (cucharaditas)1 fluid ounce (onza fluida) 29.6 milliliters (mililitros)1 teaspoon (cucharadita) 5 milliliters (mililitros)1 cup (taza) 0.24 liters (litros)1 quart (cuarto) 0.95 liters (litros)1 liter (litro) 4.227 cups (tazas)1 liter (litro) 1.057 quarts (cuartos)1 liter (litro) 0.264 U.S. gallons (galones americanos)1 U.S. gallon (galà ³n americano) 3.785 liters (litros) Area (superficie) 1 square centimeter (centà ­metro cuadrado) 0.155 square inches (pulgadas cuadradas)1 square inch (pulgada cuadrada) 6.4516 square centimeters (centà ­metros cuadrados)1 square foot (pie cuadrado) 929 square centimeters (centà ­metros cuadrados)1 acre (acre) 0.405 hectares (hectreas)1 hectare (hectrea) 2.471 acres (acres)1 square kilometer (kilà ³metro cuadrado) 0.386 square miles (millas cuadradas)1 square mile (milla cuadrada) 2.59 square kilometers (kilà ³metros cuadrados) Of course, mathematical accuracy isnt always necessary. For example, if you remember that a kilogram is a bit more than 2 pounds and a liter is a bit more than a quart, thats close enough for many purposes. And if youre driving, remember that a speed-limit sign that says 100 kilà ³metros por hora means you shouldnt be driving more than 62 miles per hour.
