Two commonly used systems of units are English units and SI units. SI units are a metric system of units, meaning values can be calculated by factors of 10. The SI base units of length, mass, and time are the meter (m), kilogram (kg), and second (s), respectively.

For most systems of units, it is convenient to define base units for length, mass, and time; a base electrical unit may also be defined, along with a few lesser-used base units.
