Treadmill Calorie Calculator

This works out the energy cost of a treadmill session from your weight, the belt speed, the incline and the time, using the ACSM walking and running metabolic equations. Those are the equations a treadmill console runs, and they are the reason the incline changes the answer: in the walking equation the gradient term carries eighteen times the weight of the speed term, so a 5 percent grade at 3 mph burns roughly two thirds more than the same walk on the flat. The result gives calories, oxygen cost, METs, belt distance, vertical climb, and how much of the total the incline added. It also says whether your speed falls inside the band each equation was fitted over, because outside that band the number still appears and quietly drifts. Holding the handrails takes a large bite out of the real cost that no formula can see.

For a walk, including an uphill one. The incline is what makes this different from a flat-ground calorie estimate: it enters the equation with eighteen times the weight that speed does.

The number on the console. 0 is flat, 5 means the belt rises 5 units for every 100 travelled.

The running equation carries a bigger speed term and a smaller grade term than the walking one, because running uphill is less costly per unit of climb than walking uphill is.
