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.
