Height & Health Context
As a body weight, 78 lb (35.38 kg, 5 st 8 lb) needs age and height before it means anything, and a conversion cannot supply that. For teenagers, weight is tracked on age and sex specific growth charts, and the adult BMI table below only applies from age 18. If 78 lb is a parcel or equipment weight, the kilo figure is what couriers and spec sheets will want.

Six stone is exactly 84 lb, so 78 lb sits 6 pounds below a milestone many UK families watch for on the bathroom scale. In kilos that gap is 2.72 kg, taking 35.38 kg up to 38.10 kg. I find people convert 78 lb most when a US size chart, a sports category limit or an old imperial scale reading needs translating into the kilos the rest of the paperwork uses.
