The U.S. is one of the few countries globally which still uses the Imperial system of measurement, where things are measured in feet, inches, pounds, ounces, etc.

What 2 measurement systems are used in the US?

Systems of measurement have historically been important, regulated and defined for the purposes of science and commerce. Systems of measurement in use include the International System of Units (SI), the modern form of the metric system, the British imperial system, and the United States customary system.

Is the US on the metric system?

The United States is now the only industrialized country in the world that does not use the metric system as its predominant system of measurement. Most Americans think that our involvement with metric measurement is relatively new.

Why the US uses the imperial system. Because of the British, of course. When the British Empire colonized North America hundreds of years ago, it brought with it the British Imperial System, which was itself a tangled mess of sub-standardized medieval weights and measurements.
