Definitions of SI Base Units

All measuring systems have basic units for length, mass (weight), capacity (volume), and temperature. The basic units for the metric system are shown in Table 1.

Units of measure are how we express measurements of quantities. For length, the unit we would use in science is meters. A unit is really only a particular amount of some quantity used as a reference point for measurements of that quantity.

The base SI units of measurement list is the second (time), meter (length), kilogram (mass), ampere (electric current), kelvin (temperature), mole (amount of substance), and candela (luminous intensity). Metric units of length include the kilometer, hectometer, dekameter, meter, decimeter, centimeter, and millimeter.

The seven SI base units, which are comprised of:
