Sl. No. Differentiating Property Mass Weight
1 Definition
  • Mass is simply the measure of the amount of matter in a body.
  • Weight is the measure of the amount of force acting on a mass due to acceleration due to gravity.
2 Denotation
  • Mass is denoted by “M”.
  • Weight is denoted by “W”.
3 Formula
  • Mass is always constant for a body and there are several formulas to calculate mass.
  • One way to calculate mass is:
    Mass = volume × density
  • Weight is the measure of the gravitational force acting on a body.
  • Weight can be calculated from the following formula:
    Weight = mass × acceleration due to gravity
4 Quantity Type
  • Mass is a base quantity.
  • Mass only has magnitude and so, it is a scalar quantity.
  • Weight is a derived quantity.
  • Weight has both magnitude and direction (towards the centre of gravity) and so, it is a vector quantity.
5 Unit of Measurement
  • The SI unit of mass is Kilogram (Kg).
  • The SI unit of weight is Newton (N).
6 Gravitational Effect
  • Mass does not depend upon gravity and is constant everywhere.
  • Mass can never be zero.
  • Weight is dependent on gravity and so, it varies from place to place.
  • Weight can be zero where there is no gravity (like space).
7 Measuring Instrument
  • Mass can be easily measured using any ordinary balance like beam balance, lever balance, pan balance, etc.
  • Weight can be measured by a spring balance or by using its formula.
