I also use a power meter for training(stages) the measurement of kj derived from watts is very accurate as it a quantifiable measurement, however it does not take into account the actual energy needed by the body to convert fuel into energy i.e thermal effects etc. Software carries out some sort of wizzardry black magic…

in Eating back calories earnt on a bike - kJ or Calories? Comment by waynetimmins January 2017
Never thought of that :/ always assumed I'd be wearing it 24/7. My edge is the 510 and the calories calculated from the power meter on my bike are slightly more accurate than just using hr alone, so I guess that would solve the problem that I don't have just yet :)
