Enter bodyweight, power, and the type of effort so you can compare absolute power and FTP-adjusted w/kg.
Estimated FTP w/kg
--
Enter a rider weight and power test to estimate watts per kilo, FTP, and a broad rider category.
Tap an example to prefill the calculator with sample values.
20-minute FTP test
75 kg rider averaging 285 watts
A standard field-test case where the 20-minute average is scaled to an estimated FTP.
Result: This is the most common scenario riders use when checking watts per kilo after a solo test effort.
Direct FTP entry
68 kg rider holding 260 watts at threshold
If you already know your FTP, you can score the current watts-per-kilo directly without any extra adjustment.
Result: Direct FTP entry is cleaner when the number comes from a recent tested or modeled threshold.
Imperial rider check
170 lb rider, 315 watts for 20 minutes
Useful when your scale and bike computer are already giving you pounds and watts.
Result: The calculator converts bodyweight internally so the final w/kg number stays comparable.
