Overview
While mass (kg) is the amount of matter in an object, weight (N) is the force exerted on that mass by gravity. This calculator helps you see how much an object would 'weigh' on different celestial bodies using the formula F = m × g.

Pro Tips
Mass is constant everywhere in the universe (ideally), but weight changes with gravity.
1 Newton is roughly the weight of a small apple (102g) on Earth.
Standard gravity on Earth is defined as exactly 9.80665 m/s².

Fun Facts
"On the Moon, you would weigh about 1/6th of what you weigh on Earth, but your mass would stay the same."
"The Newton (N) is named after Sir Isaac Newton, the father of classical mechanics."
"Jupiter's gravity is so strong that a 70kg person would weigh over 1700 Newtons there!"
