While the UK has officially adopted metric, the pound remains the cultural standard for body weight there (often via 'stones') and is the official unit of weight in the United States.

Established in 1795 as the mass of one liter of water at the freezing point, it has been the world's standard for over two centuries. Until 2019, it was defined by a physical platinum-iridium cylinder locked in a vault in Paris (Le Grand K).
