BHP = Brake Horse Power.

WHP = Wheel Horse Power

NMT = Newton Meters Torque

PS = Pferdestärke (1.0 PS = 0.9863 HP.) Used by japan

kW = Kilowatt (1.0 kW = 1.34 HP) Used by Germany and other in Europe.

Rating Standards. (what conditions the car was tested in to get its power rating)

EEC: European standard. Measure at 99kPa and 25°C. Rated in kW.

SAE: American standard. Measure at 99kPa and 25°C. Rated in hp. 1kW = 1.341hp (SAE).

DIN: German standard. Measure at 101.3kPa and 20°C. Rated in hp (ps). 1kW = 1.360hp (DIN).

JIS: Japanese standard. Theoretically same as DIN, but we always find it is actually smaller.

British Horsepower: same as SAE. Rated in bhp (could be confused with brake horse power).

Cool thread. I'm going to take this chance to ask what the difference is in....

HP Vs. WHP vs. BHP

?

HP is Horsepower, that is the amount of power your engine makes.

WHP is wheel horsepower, how much power is actually at your wheels (since the amount your motor makes is never the same as what your wheels actually put to the ground since you have to fight drivetrain loss, loss of power through the axles, size of your wheels/tires, etc).

BHP is a measurement for HP (horsepower), but in british figures.

BHP (Brake Horse Power) has to do with the way the HP was measured using a brake dynamometer like a Water brake, Fan brake, Mechanical friction brake or Prony brake, Hydraulic brake Eddy current or electromagnetic brake opposed to a Electric motor/generator

Brake horsepower (bhp) is the measure of an engine's horsepower without the loss in power caused by the gearbox, generator, differential, water pump and other auxiliaries. Thus the prefix "brake" refers to where the power is measured: at the engine's output shaft, as on an engine dynamometer. The actual horsepower delivered to the driving wheels is less. An engine would have to be retested to obtain a rating in another system. The term "brake" refers to the original use of a band brake to measure torque during the test (which is multiplied by the engine speed in revs/sec and 2*pi radians/rev to give power, which is then converted to horsepower).
