Kilograms and pounds
The kilogram is the SI base unit of mass, defined since 2019 by fixing Planck's constant to an exact value. Before that it was defined by a physical platinum-iridium cylinder kept in a vault near Paris.
The pound (lb) traces back to the Roman libra pondo ("a pound by weight"), which is also why the abbreviation is lb and not p. The modern international avoirdupois pound has been defined as exactly 0.45359237 kg since 1959.
