WebIt is called a derived unit when derived quantities are expressed in the same unit. Derived units include: · Metres per second (distance). · Moles per cubic metre (concentration of a substance). · Specific volume (cubic metre per kilogram). SI units are divided into a total of 21 different subunits.
