The kilogram (kg) is the SI base unit of mass. Since 2019 it has been defined through the Planck constant instead of a platinum-iridium cylinder kept near Paris. Kilograms are used for body weight, groceries, luggage allowances and shipping in almost every country. One kilogram is 2.20462 pounds.
The pound (lb) is defined as exactly 0.45359237 kilograms by the 1959 international agreement. Its abbreviation comes from the Roman libra. Going the other way, one pound equals 0.453592 kilograms. Pounds are used for body weight in the US and, alongside stones, in the UK, and for groceries, gym weights and parcels in the US.
