# 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

**Where,**

PWR = Power-to-weight ratio

P = Power (Determined in hp, W)

WT = Weight (Determined im kilograms or pounds)

**Note:**

To calculate power, you can use our Power Calculator.

### Example

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.

**Given data**

Power = 250 hp

Weight = 2000 kg

**To Find**

Power-to-weight ratio = ?

**Solution**

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.
