    If you know the distance you ran or walked on the treadmill, and your weight, then double check using the normal formulas.

    Run weight * distance (MI) *.63
    Walk weight * distance (MI) *.30

    The treadmill I run on at the comes pretty damn close to the above, so I don't know if it senses my weight or not. I go by my Garmin watch, which is also close. So 3 things give me about 400 cals for 5K

    @Tacklewasher the formulas you use appear to attempt to calculate net calories burned.

    The figure reported by most treadmills is gross calories burned which includes your calories for breathing and being alive.

    The formulas you quote are blatantly incomplete in that they do not account for the speed of the activity, the terrain, and or adjust for any load you may be carrying.

    They may serve as a gross sanity check but I would not rely on them for accuracy.

    If you really would like a second opinion you may want to try something like:

    Speed has no impact on the amount of calories burned but you are right the gradient would do.

    Umm, beg to differ here. All you have to do is look at the exertion between running (jogging) at, say 5 mph and running hard at 11-12 mph. There is no question as to the fact that it takes more force over less time (work, or energy) to move the same mass. That is more energy. Since calories are a unit measurement of energy, speed has to have an effect.

    [ETA - BTW, the same concept applies to a gradient. You add the work that your body does to move itself against gravity. Energy (or calories) must increase]

    I disagree

    Well the calculator you posted doesn't so I suggest you find one that agrees with you in order to support your argument........

    The rate of calorie burn is at a greater rate but you are running for half the time!!

    Here is one source for the formulas I presented. I agree that gradient matters and it seems speed does make a difference for walking, once you are past 5 mph. Speed doesn't really matter for running since it takes less time to run the mile faster, but the burn per mile will be the same.

    That relates to use on a treadmill though so not really relevant to the formula
