Enter the total power output and the cyclist’s body weight into the calculator to determine the Cycling Watts Per Kg. This calculator can also evaluate any of the variables given the others are known.

Cycling Watts Per Kg Formula

The following formula is used to calculate the Cycling Watts Per Kg.

WPK = W / KG


  • WPK is the Cycling Watts Per Kg (W/Kg) W is the total power output (Watts) KG is the cyclist’s body weight (Kilograms)

To calculate the Cycling Watts Per Kg, divide the total power output by the cyclist’s body weight. The result will be the Cycling Watts Per Kg, which is a measure of the cyclist’s power-to-weight ratio. This is a key performance indicator in cycling, especially in climbing scenarios where the cyclist’s weight can significantly impact performance.

What is a Cycling Watts Per Kg?

Cycling Watts Per Kg, also known as power-to-weight ratio, is a measurement used by cyclists to compare their performance. It is calculated by dividing the cyclist’s power output in watts by their body weight in kilograms. This ratio is important because it determines a cyclist’s ability to overcome gravity while climbing. The higher the watts per kilogram, the better a cyclist’s performance, especially in uphill or mountainous terrains.

How to Calculate Cycling Watts Per Kg?

The following steps outline how to calculate the Cycling Watts Per Kg.

  1. First, determine the total power output (Watts) of the cyclist.
  2. Next, determine the cyclist’s body weight (Kilograms).
  3. Next, gather the formula from above = WPK = W / KG.
  4. Finally, calculate the Cycling Watts Per Kg.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total power output (Watts) = 250

cyclist’s body weight (Kilograms) = 70
