How can I calculate weight?
Summary. 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.
How do I calculate BMI manually?

When using a handheld calculator, if your calculator has a square function, divide weight (lb) by height (in) squared, multiply by 703, and round to one decimal place.
