Cycling Power-to-Weight Calculator
Calculate cycling power to weight ratio
Inputs
Provide the following 2 values to run the Cycling Power-to-Weight Calculator:
- FTP (watts) [number] (required)
- Body Weight (kg) [number] (required)
What it calculates
This tool returns:
- Power/Weight (W/kg) — primary result
- Category
- FTP for Cat 2 (W)
Worked example
For the sample inputs below:
- FTP (watts): 100
- Body Weight (kg): 70
the Cycling Power-to-Weight Calculator produces:
- Power/Weight: 1.43 W/kg
- Category: Recreational
- FTP for Cat 2: 245 W
How it works
The result is derived through the following steps:
powerToWeight = ftp / weightcategory = powerToWeight >= 5 ? 'Pro' : powerToWeight >= 4 ? 'Cat 1' : powerToWeight >= 3.5 ? 'Cat 2' : powerToWeight >= 3 ? 'Cat 3' : 'Recreational'targetFTPCat2 = weight * 3.5
Frequently Asked Questions
What is the power-to-weight ratio in cycling?
The power-to-weight ratio in cycling is a measure of how much power a cyclist can generate relative to their body weight, typically expressed in watts per kilogram (W/kg). It helps determine performance and speed.
How do I use the Cycling Power-to-Weight Calculator?
To use the calculator, simply input your weight in kilograms and your average power output in watts. The calculator will then provide you with your power-to-weight ratio.
Why is the power-to-weight ratio important for cyclists?
The power-to-weight ratio is crucial for cyclists as it influences climbing ability and acceleration. Higher ratios mean better performance, especially on steep climbs.
What is a good power-to-weight ratio for cyclists?
Generally, a power-to-weight ratio of 2.0 W/kg is considered good for recreational riders, while professional cyclists often exceed 5.0 W/kg, especially during climbs.
Can the calculator be used for other athletes?
While primarily designed for cyclists, the power-to-weight concept can also apply to other endurance sports. Inputting the relevant data can help in those cases too.
