The stone unit dates back to ancient Europe when merchants used literal stones as consistent weight measures in trade. The stone’s actual value varied by country and commodity until it was officially standardized in the UK as 14 pounds in 1835.
Historically, different stone weights were used for wool, meat, and grain, ranging from 8 lb to 16 lb depending on region and market. Today, it’s primarily retained for measuring human body weight in the UK and Ireland.
While the metric system dominates globally, many people in the UK still express their body weight in stones and pounds due to cultural familiarity. For example, someone might say “I weigh 12 stone 7” rather than “79.38 kg.”
Fitness apps, personal trainers, and healthcare systems in Britain often support stones and pounds to provide better user experience for local users.
