How do you calculate weight with mass?

Answer 1

The simplified answer is that if you live on our pretty blue planet, you don't need much for a calculator. Your weight and your mass are the same. Very few people would calculate their weight from their mass, because mass is quite difficult to measure, whereas weight is easy. Everyone has a set of bathroom scales to measure weight, but you never see a slot machine labelled "I speak your mass". And yet, your mass is your fundamental property. If you mass 50Kg then here on earth you weigh 50Kg. Take a trip to the moon. On arrival you only weigh about 7Kg, but your mass is still 50Kg. On the space station, in free fall, you have no weight at all but still mass 50Kg. The complicated answer is to take your mass, multiply it by the acceleration due to gravity for the planet on which you are standing, then divide by the acceleration due to gravity on earth.

ADDED: I am afraid the "simplified" answer is incorrect. Mass and Weight are not the same, as indeed the answer does go on to show. The "complicated answer" is nearly there but then reverses itself.

Weight = Mass X g, where g is the acceleration due to gravity, and on Earth, is 9.81m/s^2. For practical purposes g is often rounded to 10.

Answer 2

Weight = mass x gravity. On Earth, gravity is about 9.8 newtons per kilogram.

Weight = mass x gravity. On Earth, gravity is about 9.8 newtons per kilogram.

Weight = mass x gravity. On Earth, gravity is about 9.8 newtons per kilogram.

Weight = mass x gravity. On Earth, gravity is about 9.8 newtons per kilogram.

Answer 3

Weight is calculated by multiplying the mass of an object by the acceleration due to gravity (9.81 m/s^2 on Earth). The formula for calculating weight is W = m x g, where W is the weight, m is the mass, and g is the acceleration due to gravity.

Answer 4

Weight = mass x gravity. On Earth, gravity is about 9.8 newtons per kilogram.

Answer 5

If you think to molecular mass this is the sum of atomic weights of the atoms contained in the molecule.
