What does 12 Stone represent?
12 stone (76.20 kg, or 168 lb) is the modal entry weight on UK adult-male driving licence records and a common reference weight for "regular" fit British men's clothing. Converted to metric the figure is 76.20 kg, which sits just above the 75 kg average adult-male body mass used in non-US airline weight-and-balance tables. It is also the upper edge of one of the older Olympic-weightlifting men's classes (the 77 kg bracket after the 2018 IWF restructure), so British amateur lifters at exactly 12 st have around 800 g of margin to make weight; coaches confirm the figure on the metric competition scale before each meet.
