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.

What do we weigh in kg?
The units of measurement for weight are grams (g) or kilograms (kg), but how do you choose which to use? As a general rule, you weigh light items in grams and heavier items in kilograms. You weigh things in grams either because they’re light or because you’re measuring small amounts of them.
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.
Why do doctors weigh in kilograms?

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.
