Mass is the amount of matter in your body \u2014 it is the same whether you stand on Earth, float on the Moon or drift through deep space. Weight is a <a href=\"https:\/\/wpcalc.com\/en\/physics\/force-physics\/\">force<\/a>: the gravitational pull acting on that mass, calculated as \\(W = m \\cdot g\\). When the local gravity \\(g\\) changes, your weight changes with it.<\/p>\n<p>The Moon's surface gravity is only 1.62 m\/s\u00b2, about 16.5% of Earth's 9.80665 m\/s\u00b2. That is why a 70 kg person weighs only about 11.6 kg (25 lb) there \u2014 not because they lost mass, but because the Moon pulls on them more gently. On Mars, with \\(g = 3.71\\) m\/s\u00b2, the same person weighs roughly 38% of their Earth weight, which is why future astronauts will be able to jump much higher and carry heavier equipment than they could at home.<\/p>\n<p>Jupiter is the opposite extreme: at 24.79 m\/s\u00b2, its cloud-top gravity is 2.53 times Earth's, so a 70 kg person would feel like they weighed nearly 177 kg. The Sun's gravity of 274 m\/s\u00b2 is about 28 times Earth's \u2014 a scale there would read almost 2 tonnes for an average adult. Note that the results are shown as scale readings (kilogram-force and pound-force). Physically, weight is measured in newtons; a scale simply converts the force back into an \"equivalent mass\" using Earth's gravity.<\/p>\n<h2>Assumptions, Limitations and Practical Notes<\/h2>\n<ul>\n<li><strong>Surface gravity values<\/strong> come from NASA's planetary fact sheets (equatorial surface gravity): Moon 1.62, Mercury 3.70, Venus 8.87, Mars 3.71, Jupiter 24.79, Saturn 10.44, Uranus 8.87, Neptune 11.15, Pluto 0.62 and the Sun 274.0 m\/s\u00b2.<\/li>\n<li><strong>The gas giants have no solid surface.<\/strong> For Jupiter, Saturn, Uranus and Neptune, \"surface\" gravity is defined at the cloud-top level where atmospheric pressure equals Earth's sea-level pressure \u2014 you could not actually stand there.<\/li>\n<li><strong>Rotation and latitude are ignored.<\/strong> A planet's spin slightly reduces the effective gravity at the equator, so real readings would vary by a fraction of a percent depending on where you stand.<\/li>\n<li><strong>Unit handling:<\/strong> if you enter pounds, they are treated as pounds-mass with 1 lb = 0.45359237 kg. The kg column shows kilogram-force (1 kgf = 2.2046226 lbf), i.e. what a spring scale calibrated on Earth would display.<\/li>\n<li><strong>Pluto is included<\/strong> as a dwarf planet for comparison \u2014 at 0.62 m\/s\u00b2, you would weigh only about 6% of your Earth weight there.<\/li>\n<\/ul>\n<h2>Where This Idea Shows Up in Physics<\/h2>\n<p>Weight is one of the most common applications of Newton's second law, \\(F = m \\cdot a\\).
