Enter the total power output (kW) and the total weight (lbs) into the KW to Weight Ratio Calculator. The calculator will evaluate the KW to Weight Ratio. 

KW to Weight Ratio Formula

The following two example problems outline the steps and information needed to calculate the KW to Weight Ratio.

KWR = P / W


  • KWR is the KW to Weight Ratio (kW/lb)
  • P is the total power output (kW) 
  • W is the total weight (lbs) 

To calculate the kW to weight ratio, divide the total power output in kW by the weight.

How to Calculate KW to Weight Ratio?

The following steps outline how to calculate the KW to Weight Ratio.

Example Problem #1:

  1. First, determine the total power output (kW).
    • The total power output (kW) is given as:: 400.
  2. Next, determine the total weight (lbs).
    • The total weight (lbs) is provided as: 10.
  3. Finally, calculate the KW to Weight Ratio using the equation above: 

KWR = P / W

The values provided above are inserted into the equation below and computed.

KWR = 400 / 10 = 40 (kW/lb)

Example Problem #2: 

For this problem, the variables required are provided below:

total power output (kW) = 400

total weight (lbs) = 500
