How accurate are calorie counters on machines?

    The subject says it all! How accurate are they?

    If a machine says that you've done 600 calories, does it really mean 600? Presumably it's "more or less 600 calories"

    Any ideas on tolerance? Is it within 5%? Or 10%?? Or what?

    Thanks.

    From my experience it depends on the machine... some things are easier to calculate than others.

    For the example the treadmill is unlikely to lie, it knows the exact speed, inclination and length of time that you have been running.

    Steppers though seem to be nonsense as you can do lots of quick little steps in succession to get ridiculously high calories.

    I would think it also depends on if you enter your age and weight.

    Actually since I replied to this, I have learnt a thing or two.

    For the treadmill.....

    They are not really accurate because the more you weigh the more you burn.

    Machines tend to calculate at an average weight of 150 1lbs, you can add 30 extra calories per hour for every 10lbs you are over the average.

    Sweet.

    When I run I presume the "calories burned" indicator is incorrect.

    However if you're consistently using the same machine it's a consistent measure of how much effort you're putting in.
