Another HP unit exists in continental Europe and is based on the energy needed to lift a weight of 75 kilos per m/second. This is the version that hydrotherapy devices refer to in their technical documentation. It is equal to 1 CV : or 735,499 W. 1 BHP is equal to 1 English HP, its use to define motor power in European standards is deliberately misleading.
