RWKW to HP Calculator



Formula

To calculate the Engine Horsepower (HP) from Rear Wheel Kilowatt Power (RWKW):

\[ HP = RWKW \times 1.15 \times 0.745 \]

What is RWKW?

RWKW, short for rear wheel kilowatts, is a measure of the power in kilowatts at the rear wheel of a vehicle. This metric is often used in automotive performance testing to determine the power output that is actually delivered to the wheels, as opposed to the power produced by the engine alone.

Example Calculation

Let's assume the following value:

Step 1: Convert the wheel power to engine power:

\[ RWKW \times 1.15 = 200 \times 1.15 = 230 \text{ kW} \]

Step 2: Convert from kW to HP:

\[ HP = 230 \times 0.745 = 171.35 \text{ HP} \]

The Engine Horsepower is 171.35 HP.
