it's only the 5252 bollocks if you want to calculate BHP (old fashioned imperial unit) using torque in lb.ft (another old fashioned imperial unit).

why don't we get with the modern world in this country and talk Nm for torque and PS (only a metric close equivalent of BHP) or better still kW for power?
