PS and bhp are so close it makes no real difference. Only 1.5%. To convert PS to bhp, multiply the PS by 0.9863. PS is still used to describe power outputs of most cars built in Europe. For example, a Focus 1.6TDCI 110 refers to 110PS. kW is the official measure in mainland Europe and is PS x 0.7355. Torque is now most commonly measured in Nm. But the old British measure was lb ft. For Nm to lb ft multiply the Nm by 0.7376.
