Since there is no practical easy way to measure mass, in everyday life we use the
kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth
. However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.

Why is weight measured in newtons?
Weight is
a measure ofthe force of gravity on a physical object
and is measured in newtons. The weight of a bird of mass 15 g varies with the magnitude ofthe gravitational force acting on it and would be considerably different if measured on the Moon, for example, instead of on Earth.

How can I calculate weight?
- Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s
2
on Earth. - The formula for calculating weight is F = m × 9.8 m/s
2
, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
