Although it is familiar with the International system, the United States uses the English system of units.
The English system of units, also known as the imperial system, is used primarily in the United States and includes units like inches, feet, pounds, and gallons. The metric system is a more widespread system of measurement used internationally, including units such as meters, kilograms, and liters. The metric system is based on powers of ten, making conversions between units easier compared to the English system.
SI units are more accurate than English system units
The United States system of units is similar to the British imperial system. Both systems are derived from English units, a system which had evolved over the years before American independence, and which had its roots in Roman and Anglo-Saxon units. ~Wikipedia
