What is Power to Weight Ratio(PWR)?
An engine's power-to-weight ratio (PWR, or power-to-mass ratio) calculates how many power units and power sources are needed to power the device. To predict the speed of a vehicle, PWR calculations are commonly used.
The metric is also used as a measure of overall vehicle performance, since the engine's power output is divided by the mass of the vehicle, resulting in a metric independent of the vehicle's size. Manufacturers usually quote power-to-weight at peak values, but actual performance will vary depending on the use. Here is the formula to calculate p to w ratio:
Power to Weight Ratio (PWR) = Power of the vehicle / Weight of the engine
Or
PWR = P / WT
Where,
- PWR = The Power to Weight Ratio, (horsepower per pound, watts per kilogram).
- P = Power (horsepower / watts)
- WT = Weight (pounds, kilograms)
In the below-given modules of this page, you can find the easy steps to know the performance of a vehicle, Also an example problem is given for a better understanding.

Power to Weight Ratio Formulas
The formulas for Power to Weight Ratio calculations used by this online calculator is as shown below:
PWR (W/kg) = P (W) / WT (kg)
Or
PWR (hp/lb) = P (hp) / WT (lb)
Conversions of Power to Weight Ratio Calculator Comparison
hp / lb = 1.643 kW / kg
kW / kg = 0.608 hp / lb
How to Calculate Hp to Kw Ratio Manually?
The simple steps for solving the horsepower to weight ratio for vehicles are provided here:
- Find out the power of the vehicle.
- Solve the curb weight of the vehicle.
- Use the direct formula to calculate Power to Weight Ratio ie., Power to Weight Ratio = Power / Weight
- Finally, the determined value is the desired Power to Weight Ratio.
Solved Example on Vehicle Power to Weight Ratio Calculation
Example:
Calculate the vehicle Power to Weight Ratio using the given particulars. The vehicle power is 450 hp and the vehicle weight is 15000 pounds.
Solution:
Given that
Vehicle power P = 450 hp
Vehicle weight W = 15000 pound
Power to weight ratio = P/W
= 450/15000
= 0.03
Therefore, the vehicle Power to Weight Ratio is 0.03.

FAQs On Power to Weight Ratio Calculator with Steps
1. How do you calculate Power-to-Weight Ratio?
Power to Weight Ratio is obtained by dividing the power output of a vehicle by its weight. Else, you can also calculate the hp to kW ratio using the free online tool ie., power to weight ratio calculator.
2. How many pounds does 1 HP move?
The constant 1 hp = 550 foot-pounds per second, also it means 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.
3. What is a good power to weight ratio for a car?
100 BHP/ton is the latest decent power-to-weight ratio.
4. Is a higher Power to Weight Ratio better?
The higher horsepower equals higher speed but sheer acceleration ability and speed depend on weight ratio this means that the ideal performance vehicle is lighter in curb weight but jacket to the hilt in horsepower.
5. Is Power to Weight Ratio important?
The Power to Weight Ratio is an important factor for vehicle performance. A vehicle with less weight will allow a smaller and lighter engine with less power to accelerate fast and reach the maximum speed as a heavy vehicle.
