Difference Between Mass and Weight

Weight is the force with which gravity pulls on mass.

Perhaps the simplest way to explain the difference is that on the Moon or on Mars, your weight is reduced because gravity is weaker, but your mass remains the same.

DefinitionMass is the quantity of matter in a body regardless of its volume or of any forces acting on it.Weight is a measurement of the gravitational force acting on an object.
Effect of gravityMass is always constant at any place and any timeThe weight of an object depends on the gravity at that place
Unit of MeasurementMass is expressed in kilogram (kg), grams (g), and milligram (mg).Weight is expressed in Newton (N)
Balance used for measurementMass is measured using a pan balance, a triple-beam balance, lever balance or electronic balance.Weight is measured using a spring balance.
Type of quantityScalar and base quantityVector and derived quantity
