Enter your functional threshold power (kW) and weight (lbs) into the Cycling Power to Weight Ratio Calculator. The calculator will evaluate and display the Cycling Power to Weight Ratio.

## Cycling Power to Weight Ratio Formula

The following formula is used to calculate the Cycling Power to Weight Ratio.

CPW = CP / W
• Where CPW is the Cycling Power to Weight Ratio (kW/lb)
• CP is functional threshold power (kW)
• W is your weight (lbs)

To calculate the cycling power-to-weight ratio, divide the functional threshold power by the body weight.

## How to Calculate Cycling Power to Weight Ratio?

The following example problems outline how to calculate Cycling Power to Weight Ratio.

Example Problem #1:

1. First, determine the function threshold power (kW).
• The function threshold power (kW) is given as: 100.
2. Next, determine the your weight (lbs).
• The your weight (lbs) is provided as: 150.
3. Finally, calculate the Cycling Power to Weight Ratio using the equation above:

CPW = CP / W

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

CPW = 100 / 150 = .66 (kW/lb)

## FAQ

What is Functional Threshold Power in cycling?

Functional Threshold Power (FTP) is the highest power a cyclist can maintain in a steady state for an hour without fatiguing. It’s a key metric used to guide training intensity and track fitness improvements over time.

Why is the Power-to-Weight Ratio important for cyclists?

The Power-to-Weight Ratio (PWR) is crucial because it determines a cyclist’s ability to perform, especially on climbs. A higher PWR means a cyclist can produce more power while maintaining a lower weight, making them faster, particularly on uphill gradients.

How can a cyclist improve their Power-to-Weight Ratio?

Improving the Power-to-Weight Ratio can be achieved by either increasing functional threshold power through structured training or reducing body weight while maintaining power output. Ideally, a combination of both strategies is used for optimal performance gains.
