Power to Weight Ratio Calculator
If you want to determine the proportion between the power and weight, then you can use our power-to-weight ratio calculator.
What is the power-to-weight ratio?
To understand the ratio between power and weight, let us discuss the weight and power individually. Power is defined as the value of work performed on an object. Whereas weight is defined as the ratio of the gravitational force of acting on a body, the weight formula is w = mg, and power is P = W/t. Now, the power-to-weight ratio signifies the proportion between a vehicle's power and its total weight. The more eminent the PWR, the more accelerated the vehicle will be. It is a reason bikes accelerate faster than many cars.

Formula of Power to Weight Ratio Calculator
From Hooke's law, we get
PWR = P / WT
PWR = Power-to-weight ratio
P = Power (Determined in hp, W)
WT = Weight (Determined im kilograms or pounds)
To calculate power, you can use our Power Calculator.
For a more precise understanding of a concept and to know how to find out the power-to-weight ratio, let us have an example below:
Suppose if you have a vehicle weighing 2000 kgs and has a horsepower of 250 hp, then determine the PWR of a vehicle.
Power = 250 hp
Weight = 2000 kg
Power-to-weight ratio = ?
To find out the Power-to-weight ratio of a vehicle, we will use the formula listed below:
PWR = P / WT
Putting values in the above formula
PWR = 250 / 2000 = 0.125 hp / each pound of a vehicle.
