Bike power-to-weight calculator guide
WeCovr's bike power-to-weight calculator estimates watts per kilogram from power output and body weight.
What this power-to-weight calculator does
This page divides cycling power by body weight to estimate watts per kilogram.
Returns W/kg.
Uses power and body weight.
Helpful for comparing climbing-oriented cycling fitness.
Why watts per kilogram matters
Power-to-weight ratio is widely used in cycling because weight matters a lot on climbs and in repeated accelerations.
What this result does not capture
Aerodynamics, fatigue resistance, handling, and actual race tactics still matter, so W/kg is helpful but not complete on its own.

FAQs
Should I use body weight or system weight?
Many riders use body weight for W/kg comparisons, but system weight can matter more for some climbing calculations.
Is a higher W/kg always better?
Higher is generally helpful, but it is not the only factor in cycling performance.
Does this replace FTP testing?
No. It only converts a given power value into a relative weight-based figure.
