History of the kilogram and the pound
The kilogram was the last unit of the metric system to be defined by an object: for more than two centuries it was a metal cylinder kept in a vault, until it was tied to a constant of nature.
- A cylinder of platinum, the kilogram of the Archives, became the standard of mass in France.
- The international prototype of the kilogram, a cylinder of platinum and iridium kept near Paris, became the kilogram for the whole world.
- Six countries agreed on an international pound of exactly 0.45359237 kg, the value the pound still has.
- The kilogram was redefined by fixing the Planck constant, and the prototype stopped being the standard.
