in simple words, Mass is the amount of matter present in a substance or body, while weight is the force which which a body feels due to gravity i.e force exerted by the Earth. As a matter of fact is comes equal to mass times of g (gravity)

Mass is the amount of matter present in a body and is an intrinsic property of the body. Mass of an object remains the same always at any place. Weight on the other hand is the force which a given mass feels due to the gravity at its place. Weight is measured in units of Force like Newton (which is the SI unit of Force). If your mass is 60 kgs then your weight is approximately 60 x 10 = 600 Newtons. This is because Force = mass x acceleration (From Newton’s second Law) Thus, weight = mass x acceleration due to gravity If you go to moon your mass remains same, i.e 60 kgs, but your weight becomes less by 1/6 amount, since moon’s gravity is 1/6 that of earth. Mass of a body is measured by balancing it equally with another known amount of mass. You keep known amount of masses like blocks of 1 kg, 2 kg etc on one side till both the sides balance and then add up the numbers on the known side of mass and thus calculate the unknown mass. This works because, when the masses are equal on both the sides of the balance the effect of gravity cancels out for both (i.e weight cancels out) and hence we can calculate the mass on one side of the balance if we know the mass on the other side of the balance. Weight is measured using a scale which effectively measures the pull on the mass exerted by the gravity of the earth.

Mass Weight 1. Is always a constant at any place and time Depends on gravity at the place

  1. Is measured in kilograms in SI unit Is measured in Newtons (not in

kilograms as one might think)

  1. Is measured using balance Is measured using scales

  2. Can never be zero Can also be zero
