MEASUREMENT.
In order to measure we need to know or define the quantity to be measured and the units for measuring it.
In 1971 a system known as the International System of Units (Systeme’ Internationale) and seven basic units were agreed upon as follows. Other quantities can be obtained from these basic quantities and are referred to as derived quantities.
