What is a kilogram?
The kilogram is the SI base unit of mass. Since 2019 it has been defined from the Planck constant rather than from a metal cylinder kept near Paris. Most countries use it for body weight, luggage allowances and groceries; one kilogram is about 2.2 pounds.
What is a stone?
The stone equals 14 pounds, about 6.35 kilograms. It is still how people in the United Kingdom and Ireland state their body weight, as in 11 st 4 lb. It is rarely used in the United States or for anything other than people.
