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.

Your mass is the same no matter where you go in the universe
; your weight, on the other hand, changes from place to place. Mass is measured in kilograms; even though we usually talk about weight in kilograms, strictly speaking it should be measured in newtons, the units of force.
What does G mean in weight?
Gram (g), also spelled gramme,
unit of mass or weight
that is used especially in the centimetre-gram-second system of measurement (see International System of Units). … The gram of force is equal to the weight of a gram of mass under standard gravity.
What is an ideal weight?
