SI Units of Measurement: Metric System

  • Scientists all over the world use a set of measuring units called the International System of Units (SI).

    • SI is a revised version of the metric system, which is based on multiples of 10.

  • SI is built upon seven base units and many derived units.

    • For example, the base unit for length is meter (m) and the derived unit for volume (length x length x length) is cubic meters (m3).

Metric system of measurement

Metric System of Measurement

  • Measurements must have a value and a unit (for example, 53 meters).

  • A metric prefix indicates how many times a unit should be multiplied or divided by 10. For example, 1000 meters = 1 kilometer.

    • The prefix “kilo-” tells us that we need to multiply km by 1000 to convert to m.

  • A conversion factor is a ratio of equivalent measurements that is used to convert a quantity of one unit to another.

    • To convert s to ms, you would multiply by a conversion factor of 1000 ms/1 s.
