Mass / Weight Converter
Convert between 10 mass / weight units.
About Mass / Weight
Mass is how much matter something contains; weight is the force gravity applies to it. Everyday use treats them as the same thing, and so does this converter, because scales are calibrated for Earth's gravity. The kilogram has been defined by the Planck constant since 2019, replacing the metal cylinder kept in Paris. A pound is exactly 0.45359237 kilograms, so a 150 lb person is about 68 kg.
