Mass is a fundamental property of matter that measures the amount of substance in an object. Unlike weight, which changes with gravity, mass remains constant whether you're on Earth, the Moon, or in space. Our mass converter handles everything from microscopic measurements in nanograms to astronomical scales in solar masses, supporting both metric and imperial systems used worldwide.
The kilogram has a fascinating history as the only SI base unit originally defined by a physical artifact. From 1889 to 2019, the International Prototype of the Kilogram (IPK)—a platinum-iridium cylinder stored in Paris—was the world's standard. In 2019, the kilogram was redefined using the Planck constant, ensuring it can be precisely reproduced anywhere in the universe. The imperial system's pound originated from the Roman libra, while the metric system emerged from revolutionary France's desire for a universal, decimal-based system.
Multiply the mass in kilograms by 2.20462 to get pounds.
Example: 75 kg × 2.20462 = 165.35 pounds
Multiply the mass in pounds by 0.453592 to get kilograms.
Example: 150 lbs × 0.453592 = 68.04 kg
Multiply grams by 0.035274 to convert to ounces.
Example: 250 g × 0.035274 = 8.82 ounces
Multiply stones by 6.35029 to get kilograms.
Example: 12 stone × 6.35029 = 76.2 kg
