# The Basic Units of Measurement

Over centuries, several units have been devised to calculate exact measurement of different kinds. These units can be divided into two kindsâ€”SI units and non SI units. SI units refer to the set of physical units called International System of Units which is used in the scientific world. Non-SI units are all the other units which are commonly used. Knowledge of SI units is important since these are the units majorly used in scientific work and incorrect usage of scientific units can lead to incorrect results in most cases.

Here is a list ofÂ SI unitsÂ of quantification for you to study.
