Weight tools
Convert between metric and imperial mass units. The pound has been exactly 0.45359237 kg since 1959, so pound-to-kilogram conversions are exact. Note that the carat used for gemstones is exactly 200 mg and is unrelated to the karat used for gold purity.
About mass conversion
What everyday language calls weight is properly mass, and its SI base unit is the kilogram. Since 2019 the kilogram has been defined by a fundamental constant of nature rather than by a physical artefact.
