These are called derived units. In the SI system (or metric system), there are base units for length, mass and time, among others. These are:
The unit of acceleration is expressed as m/s2. An example of a derived unit is the unit of force called the newton (N). Force is equal to mass multiplied by acceleration. Therefore:
force = mass × acceleration
N = kg·m/s2

Derived units
Weight is measured in units called Newton, while mass is measured in units called grams and kilograms.
