Cycling Power to Weight Calculator
Calculate your cycling power to weight ratio in watts per kilogram, the number that best predicts how fast you climb and how you stack up against other riders. Power to weight is your sustainable power, usually your functional threshold power, divided by your body weight in kilograms. Because gravity does not care about raw watts on a climb, a lighter rider with the same power accelerates uphill faster, which is why watts per kilogram matters more than watts alone for climbing. Enter your FTP in watts and your body weight, choosing kilograms or pounds, and the tool returns your watts per kilogram to two decimals along with a rough category label from recreational up to elite. Use it to track fitness, set climbing goals or compare against benchmark tables. The calculation is instant and stays entirely inside your browser.
How to use Cycling Power to Weight Calculator
- Enter your FTP in watts.
- Enter your body weight in kilograms.
- Read your power to weight in w/kg.
- See the rider category the value falls into.
Frequently asked questions
How is power to weight calculated?
It divides your functional threshold power in watts by your body weight in kilograms to give watts per kilogram, or w/kg.
Why is w/kg a better fitness measure than raw watts?
On climbs and against gravity your weight matters, so w/kg predicts climbing and overall cycling performance better than absolute power alone.
What w/kg range fits a category?
Recreational riders often sit near 2 to 3 w/kg, strong amateurs around 4 w/kg and elite riders above 5 w/kg at threshold, which the tool maps to a category.
