Question

Why we tend to measure weight in kg rather than newton?

Answer 1

Weight

1. It is the gravitational force applied on an object due to it's mass.

Reason that why is weight measured in kg.

1. Actual SI unit of weight is Newton.
2. SI unit of mass is kg.
3. We don't have any practical way of measuring mass of an object.
4. We assume that gravitational field is fairly same across the globe so keeping it constant we assume our weight as mass.

Final Answer: Assuming gravitational field same round the world we consider our weight as mass and use kg to measure weight.
