**Scalars** are simple numbers.They are used for measuring things. Many things can be measured, and the measure can be explained by only giving the number.

Suppose we are measuring a rod. We could give the measured length as 2 metres or 3 cm etc. depending on the length of the rod under observation. Here only the figure 2 or 3 along with the unit of measure is enough to transmit information about the rod.

Other examples of scalars are:

- Unit of mass. (Kilograms)
- Unit of measuring luminosity. (Candela)
- Unit of length. (Metres)

i.e. mass is measured by scalars, distances are measured by scalars.

The other family of measurement falls under the category of vectors.
