Dear student
W = m ∗ g W = m * g W=m∗gComparing Mass and Weight
Mass is a property of matter. The mass of an object is the same everywhere. Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity.
Mass may be measured using an ordinary balance. Weight is measured using a spring balance.

l. 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.
