Calculate Weight

Weight and mass are colloquially used synonymously, although mass is often meant when one says weight. Mass is, however, a property of matter and weight is the force that mass exerts in the gravitational field. The mass is given in kilograms, the weight in Newtons and the conversion factor is derived from the acceleration due to gravity in the gravitational field in which one is located. For us, this is in most or almost in any cases that of the Earth.

The formula for the calculation is: weight = mass * gravitational acceleration, G = m * g

Please enter two of the top three values, the third value and the apparent mass will be calculated.

Example: 55 kilograms on Earth exert a weight of 539.55 Newtons. On the Moon, however, the weight would be 86.35 Newtons, and the mass would seem like 8.8 kilograms compared to Earth, even though the mass on the Moon is still 55 kilograms.

The location factor can be set to the Sun, Moon or one of our planets. It differs slightly depending on the position on the planet, so for the Earth you can choose between an average value and the values ​​at the poles and the equator. For the other celestial bodies, these are the average values. The apparent mass here is what you mean when you say, for example, "On the Moon I would weigh x kilograms". This value only makes sense if you choose a location factor other than that of the Earth.

The distinction between mass and weight goes back to Isaac Newton and his law of gravitation from 1665/66, where he predicted that gravity (closely related to weight) decreases quadratically with the distance between bodies, but mass remains constant. The unit of force owes its name to Newton.
