Height & Health Context
As a body weight, 80 lb converts to 36.29 kg or 5 st 10 lb, and its meaning depends on height, age and build, which a conversion cannot show. I see 80 lb most often as an equipment figure: dumbbell pairs, kettlebell sets and luggage allowances. For any of those, check the manufacturer's stamped limit rather than relying on the conversion alone.
