Weight is mass times gravity
Physics separates the two ideas people usually merge. Mass is how much matter an object contains; weight is the gravitational force acting on it, W = m·g, measured in newtons. Because g varies — about 9.81 m/s² on Earth, 1.62 on the Moon, 3.71 on Mars, and a crushing 24.79 on Jupiter — the same person steps on different scales in different worlds while their mass never changes.
Reading the force units
One kilogram-force (kgf) is the weight of one kilogram under standard Earth gravity, so on Earth the newton and kilogram-force rows differ only by a factor of 9.80665. Pound-force (lbf) is the imperial counterpart: a 1 kg mass weighs about 2.205 lbf on Earth. Engineers quote thrust, tension, and loads in these force units, while grocery scales report mass — that is why 10 kg of flour stays 10 kg on the Moon but would press with only 1.62 kgf there.
Häufige Fragen
Why does the calculator ask for mass instead of weight?
Weight is the answer, not the input: it depends on where the object is. You supply the mass — which travels unchanged from Earth to Mars — and choose a world; the calculator multiplies by that world’s surface gravity to produce the weight in newtons.
What gravity should I enter for a custom body?
Use the surface gravity in m/s². Useful references: Venus 8.87, Saturn 10.44, Uranus 8.87, Neptune 11.15, and Earth’s own standard value 9.80665. Any positive value works, so lab centrifuges or hypothetical worlds are fine too.
