Metrication in Guatemala

In Guatemala the metric system is official but it uses a mixture of U.S., metric and Spanish customary units.

History

In May 1910 most of Central America adopted a common system of measurements.^[1]

In May 1921 Guatemala became officially metric.^[1]

Non metric units used today

Among the Guatemalan units of measurement some are based on old Spanish units; they include the vara and cuadra linear measurements; the vara cuadrada, the manzana and the cuerda units of area; and the libra, arroba, quintal and garrafón units of weight and volume.

The vara cuadrada or square vara is commonly used in land transactions in Guatemala and 10,000 square varas equal one manzana.^[2]

One square vara equals 0.6987 square metres (7.521 sq ft), while one manzana equals 6,987 square metres (1.727 acres).^[2]

A Spanish pound (libra) is 460 grams.^[2]

Some United States customary units are also used. These include inches, feet, miles, gallons, pounds (note the Spanish pound is also used) and ounces.^[2]
