About This Conversion
Pounds to kilograms is needed for US body weights, shipping weights and gym equipment specified in imperial. The conversion is exact in this direction, since the pound is defined as 0.45359237 kg rather than measured against it.
Weightlifting is a place where the conversion is deliberately not applied. Olympic plates are metric, so a 45 lb plate is really a 20 kg plate weighing 44.09 lb. Loading a bar by converting imperial numbers gives a total that is consistently a couple of pounds light.
