Power to weight ratio (PWR) is a measurement of the performance of a power source or engine. It is also used to measure the vehicle performance as a whole. Generally, PWR is applied to cars, vehicles, air crafts to compare the performance of one with another.
Power to Weight Ratio formulas is PWR = Power of the vehicle /Weight of the engine
Weight = Power of the vehicle/PWR
Power = PWR * weight
Question: Find the vehicle hosepower to weight ratio with vehicle power and vehicle weight. The vehicle power is 350 hp and the vehicle weight is 12000 pound.
Vehicle power P = 350 hp
Vehicle weight W = 12000 pound
Power to weight ratio = P/W
Therefore, the vehicle hosepower to weight ratio is 0.029.

1. What is meant by Power to Weight Ratio?
PWR means the amount of power a vehicle has relative to its weight. In simple words, divide the power of the engine by the weight of the vehicle to get its performance.
2. Is it better to have a higher or lower power to weight ratio?
It is better to have a higher power to weight ratio. Because the vehicles having higher PWR accelerates with the highest speed and the vehicles which are having the lowest PWR accelerates with lesser speed.
3. What are the units of PWR?
The most commonly used units of power-weight ratio are horsepower per pound (hp/lb) and kilowatt per kilogram (kW/kg)
4. How to measure the performance of a car using PWR?
Students have to provide engine power and vehicle weight in the mentioned input fields of the Power to Weight Ratio Calculator and hit the calculate button to get the performance easily.
