Calories burned
skiing
684 kcal / hour Skiing burns approximately 684 calories per hour for a 70 kg (154 lb) adult, and 342 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 488 to 1,172 kcal.
It carries a MET value of 9.3 in the 2024 Adult Compendium of Physical Activities, which lists 17 measured variations of this activity from MET 4.3 to 16.
Calories burned skiing by body weight
Energy cost scales with the mass you move, so body weight changes the answer more than anything else.
| Body weight | 15 min | 30 min | 45 min | 60 min | 90 min |
|---|---|---|---|---|---|
| 50 kg (110 lb) | 122 | 244 | 366 | 488 | 732 |
| 60 kg (132 lb) | 146 | 293 | 439 | 586 | 879 |
| 70 kg (154 lb) | 171 | 342 | 513 | 684 | 1,025 |
| 80 kg (176 lb) | 195 | 391 | 586 | 781 | 1,172 |
| 90 kg (198 lb) | 220 | 439 | 659 | 879 | 1,318 |
| 100 kg (220 lb) | 244 | 488 | 732 | 977 | 1,465 |

Every official intensity of skiing
The Compendium lists 17 separate skiing entries, each with its own measured MET value — from 4.3 to 16. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.

What 684 calories an hour actually means
At MET 9.3, skiing counts as very vigorous activity — it uses about 9.3 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 11 kcal per minute, or 684 kcal across a full hour.
Within water activities, that ranks 7th of 29 activities by energy cost, a little below windsurfing (MET 9.5) and above kayaking (MET 9).
Put differently: one hour of skiing costs about the same energy as 140 minutes of ordinary walking.
On the food side, a slice of pizza (about 285 kcal) takes roughly 25 minutes of skiing to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.
Questions
How many calories does skiing burn per hour?
About 684 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 9.3. A 90 kg adult burns closer to 879 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of skiing burn?
Roughly 342 kcal at 70 kg, 293 kcal at 60 kg and 488 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of skiing?
9.3, taken as the median of the 17 skiing entries in the 2024 Adult Compendium, which range from 4.3 to 16 depending on intensity. One MET is the energy you use sitting quietly, so MET 9.3 means 9.3 times that rate.
Is this an exact number of calories?
No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.
