Mass and weight
... The weight of an object is a force and is so is measured in Newtons, while the mass of an object is measured in kilograms. To find the weight of an object you simply multiply its mass (in kilograms) by the force of the Earth’s gravity on 1 kg (10N). Weight (W, Newtons) = Mass (m, kg) x Gravitational ...
