Scalar quantity is a type of Physical quantity that has only magnitude. Examples: Volume, speed, time, density, mass and energy. It means the expression in scalar will give the complete meaning. Suppose the mass of a body is 10 kg. It means it has a unit here is Kg and a numerical value that is 10. So the parameters of scalar quantities are –

  • A unit that expresses the measurement completely
  • A number or a numerical value that makes it easy to understand that unit with an accurate number.

There are some pure scalars and this does not have any unit as pie or π, e2 and some other similar types. A number of expressions are there in which you just need to understand that it has proper direction or not, in case you do not have proper knowledge about a scalar, then you can be confused as the only difference between a scalar and a vector is a proper direction.
