Gravity and Weight

Weight is the measure of the force of gravity acting on a mass.

Weight is measured in newtons*.

For example, the Earth exerts a gravitational force of about 10 newtons for every kilogram of mass on its surface.

So, if your mass is 60 kg, then your weight can be calculated with the following formula:

Weight = Mass × Gravity

= 65 × 10

= 650 newtons
