English Engineering units

Some fields of engineering in the United States use a system of measurement of physical quantities known as the English Engineering units. The system is based on English units of measure.

The English Engineering units is a set of consistent units still in use in the United States. The set is defined by the following units, with a comparison to the standard units based on the International System of Units.
