Enter the total horsepower (hp) and the total weight (lbs) into the HP to Weight Ratio Calculator. The calculator will evaluate and display the HP to Weight Ratio.

HP to Weight Ratio Formula

The following formula is used to calculate the HP to Weight Ratio.

HPWR = HP / W
• Where HPWR is the HP to Weight Ratio (hp/lb)
• HP is the total horsepower (hp)
• W is the total weight (lbs)

To calculate the hp to weight ratio, divide the total horsepower by the total weight.

How to Calculate HP to Weight Ratio?

The following example problems outline how to calculate HP to Weight Ratio.

Example Problem #1:

1. First, determine the total horsepower (hp).
• The total horsepower (hp) is given as: 600.
2. Next, determine the total weight (lbs).
• The total weight (lbs) is provided as: 2000.
3. Finally, calculate the HP to Weight Ratio using the equation above:

HPWR = HP / W

The values given above are inserted into the equation below and the solution is calculated:

HPWR = 600 / 2000 = .30 (hp/lb)

Example Problem #2:

For this problem, the variables required are provided below:

total horsepower (hp) = 7000

total weight (lbs) = 3000
