What does 120 Kilograms represent?

120 kilograms (18.90 stone, or 18 st 12 lb) sits inside the "super heavyweight" class in international amateur boxing and well above the 105 kg Olympic-weightlifting cap. Converted to British imperial the figure is 18 st 12 lb, which is the typical entry on UK NHS bariatric-surgery referral records for a patient with comorbidities. It is also the threshold above which many UK domestic ergonomic chairs and beds require a heavy-duty rating under BS EN 1335, with the 120 kg figure cross-listed as "18 st 12 lb" on UK retail tags. British weighing-scale manufacturers like Salter publish their consumer scales' upper limits in both kg and stone for this bracket.
