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/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

The SI unit of mass is the kilogram (kg). Thus, the SI unit of the quantity weight defined in this way (force) is the newton (N).
Is force due to gravity weight?
Weight is a non-contact force because gravity exerts its force through a field. An object does not need to be touching the Earth to have a weight. The weight of an object can be measured using a calibrated spring-balance, often called a Newton meter. Weight is also referred to as ‘gravity force‘.
