Comment on How is the calories meter on exercise bikes accurate

Humans are about 25 % efficient. Not bad, but also not that good. So factor 4 to wherever actual work you did. The question is: Does the bike take that into account already?

Is that 25% efficient at burning calories to produce force or inefficient at converting food into usable calories?

I meant to say in the spending of our calories through our muscles

  Input to output of a human. So 1000 kJ food = 250 kJ work done with muscles.

    Makes sense. So the bike gives kJ in work done with muscles, which I guess is even more confusing.

    I do not know if that is the case.
