Dude. You don't use efficiency to convert energy in kJ into energy in kcal. Think about. Or read this again, and verify via google or wiki or whatever cycling page you like:
That is not exactly a complicated formula.
It’s true that 1 kcal = 4.184 kJ. However, anyone that could put out 400w for an hour and thus produce 1440kj while only using 344 kcal in that hour would absolutely destroy everyone else in the tour. Imagine doing 400w for 6 hours straight and only burning about 2000 kcal ?. You’re in over your head here and I don’t blame you since you obviously have no cycling background.
1 kcal = 4.184 kJ of output to the cranks if there is 100% efficiency. Humans riding bikes are around 25% efficient, generally a bit less.
You obviously don’t ride and have zero experience with powermeters. You are truly a casual observer at best.
No....that would be our illustrious troll; Jon Orange.
