Cycling energy calculator guide
WeCovr's cycling energy calculator estimates ride energy use from average power, ride duration, and a simple efficiency assumption.
What this cycling-energy calculator does
This page converts average cycling power and ride time into estimated mechanical work and approximate energy expenditure.
Uses average watts and ride duration.
Applies a simple gross-efficiency assumption.
Returns estimated ride kJ and kcal.
Why cycling kJ and kcal are often discussed together
Cyclists often compare ride work in kilojoules with calorie use because the numbers can land in a similar range when efficiency is around the low-to-mid 20% range.
Why the result is approximate
Real energy cost depends on physiology, bike fit, cadence, terrain, drivetrain losses, and how accurately power is measured.

FAQs
Is cycling kJ the same as calories burned?
Not exactly. Mechanical work and metabolic energy are different, even though the headline numbers can sometimes look similar.
Why does efficiency matter?
Because your body uses more energy than the measured work at the pedals. Efficiency bridges that gap.
Can I use this without a power meter?
You need an average power estimate for this version of the calculator to be useful.
