How to Calculate Skating Calories in 5 Simple Steps

Skating calories in one line

Skating calories are counted in four moves: turn the weight from pounds into kilograms, multiply by the MET value for calories an hour, scale by the minutes for the session total, and divide by the minutes for calories a minute. A 180 lb skater, skating for 60 minutes at MET 7, burns 571.53 kcal. Everything else in this guide is about getting the weight, the minutes, and the MET honest, because the formula is simple and the inputs are where calorie estimates go wrong.

Step 1: Weigh yourself before the rink

Weigh yourself in pounds before anything else: the worked example uses 180 lb. The weight that matters is the weight actually moving on the ice, because every lap, turn, and push-off moves that weight and the formula charges for it. Weigh on the day, not from memory, because a weight remembered from last year is a burn remembered from last year too: twenty pounds of error moves the 60-minute burn by about sixty-three calories, which is nearly seven minutes of skating. The figure that results is the weight input, and it is the number that scales the whole burn, because the MET formula multiplies it — through the kilograms — by every minute skated.

Step 2: Convert pounds to kilograms

Convert the pounds to kilograms: 180 × 0.45359237 = 81.65 kg. This is the weight in the units the MET formula is defined in, and it is the number everything else is multiplied from, because calories an hour equal MET × weight in kilograms. One pound is 0.45359237 kilograms, so the pounds multiplied by that figure give kilograms, and a weight converted by a round 0.45 instead comes out short by more than half a kilogram — a small error, but one that rides through every minute that follows. Check the kilograms against feel before trusting them: 81.65 kg should feel like a solid adult weight, and if the kilograms look like a child or a heavyweight, the pounds or the conversion are wrong, usually the pounds, guessed instead of weighed.

Step 3: Pick the MET value honestly

Pick the MET value for the skating: the worked example uses 7. A MET value is how many times harder an activity is than sitting still, and steady recreational skating with continuous laps sits at 7 — a gentle glide nearer 5, fast laps nearer 9. Pick the average across the whole session, gentle laps and rests included, not the fastest lap: a session that mixes easy gliding with a few quick laps is not a 7 all the way through, and a MET borrowed from the fastest lap lifts the whole session by more than a quarter. The figure that results is the intensity input, and it is the number that sets the calories of every minute, because the per-hour figure is this value multiplied by the kilograms: at MET 7 the hour is 571.53 kcal, at MET 5 it is 408.23 kcal, and at MET 9 it is 734.82 kcal.

Step 4: Multiply MET by kilograms for calories an hour

Multiply the MET value by the kilograms: 7 × 81.65 = 571.53 kcal an hour. This is the burn rate, and it is the figure to compare exercises by — a rate, not a session total, because sessions differ in length and only the rate compares fairly. Check the rate against feel before trusting it: 571.53 kcal an hour should feel like steady, continuous skating, roughly nine and a half calories every minute, and if the rate looks like a hard run, the MET is too high, usually picked from ambition rather than the rink. The rate figure is also the number to use when a different intensity is weighed against a different weight, because both levers act on this figure alone: doubling the MET doubles it, doubling the weight doubles it, and halving either halves it.

Step 5: Scale by minutes, and sanity-check it

Scale the hourly rate by the minutes: 571.53 × 60 ÷ 60 = 571.53 kcal, and 571.53 ÷ 60 = 9.53 kcal a minute. This is the session total and the per-minute figure, and they are the numbers to set against a daily target — sixty minutes of steady skating burns about five hundred and seventy-two calories, which is a real contribution to a day without being a meal in itself. Sanity-check the total against the rate: 571.53 kcal over 60 minutes should equal the hourly rate itself, since 60 minutes is a full hour, and 571.53 = 571.53 — the figures agree, which is the check that the minutes were scaled and not merely added. For the interactive version, use the skating calories calculator, which runs the same four moves on any weight, minutes, and MET value.

Worked example, start to finish

Weight 180 lb, 60 minutes, MET 7. Kilograms: 180 × 0.45359237 = 81.65 kg. Per hour: 7 × 81.65 = 571.53 kcal. Total: 571.53 × 60 ÷ 60 = 571.53 kcal. Per minute: 571.53 ÷ 60 = 9.53 kcal. The same five steps on 90 minutes give 857.3 kcal; at 150 lb they give 476.27 kcal; and at MET 9 they give 734.82 kcal. Weight, minutes, and MET are the only three levers, and the kilogram conversion is the only fixed number in the whole calculation.

Three mistakes to avoid

The first mistake is counting rink time as skating: minutes lacing up and resting at the boards are not minutes on the ice, and a session with ten minutes at the boards burns for fifty skating minutes, not sixty. The second mistake is skipping the kilogram conversion: multiplying MET by pounds instead of kilograms overstates the burn by more than double, which is the largest error in skating maths and the easiest to make. The third mistake is picking the peak MET: a session is an average, not a highlight, and a MET borrowed from the fastest lap lifts every minute that follows. Weigh on the day, convert to kilograms, average the MET, scale by skating minutes only — in that order, every time a session is turned into calories.
