Estimate how many calories you burn skiing or snowboarding from your body weight, active time on the slopes and effort level, using published MET values.
Skiing MET Calorie Equation
The standard MET equation combines activity intensity, body mass in kilograms, and active minutes. Chairlift, lodge, and other inactive time should not be entered.
How the Calculation Works
Only the source values needed for the selected output remain visible and enabled. The requested output is not an input. Changing a value marks the prior successful result as out of date until you select Calculate again.
How to Use This Calculator
- Select Gross calories, Active duration, or Equation-implied body weight in the Solve for menu.
- Enter only the visible source values and their explicit units.
- Select Calculate and review the estimate and Calculation details. Numeric inputs begin blank; the effort category is an explicit selection.
- Use Reset to clear the numeric inputs and this calculator’s saved calculation. Unsaved edits do not overwrite the last successful snapshot.
Worked Example
At 6.3 MET, a 70 kg person skiing for 60 active minutes has an estimated gross expenditure of 6.3 × 3.5 × 70 ÷ 200 × 60 = 463.05 kcal, displayed as 463.1 kcal. The duration and equation-implied body-weight modes reverse this same equation.
Input and Result Guide
| Item | How to use it |
|---|---|
| 4.3 MET | Light alpine skiing. |
| 6.3 MET | Moderate skiing. |
| 8.0 MET | Vigorous skiing. |
| Active time | Count time actually skiing, not the entire resort visit. |
| Gross calories | Includes resting energy during the activity interval. |
Interpreting the Result
Use the estimate for broad comparisons of adult downhill-skiing scenarios. It is not a direct measurement and may differ from a wearable or laboratory result. Inverse modes require gross calories, not net or tracker “active calories.” Equation-implied body weight is an algebraic check and cannot measure a person’s actual weight.
Assumptions and Limitations
Adult Compendium METs are population means developed primarily for adults ages 19–59 without conditions materially altering energy expenditure. Terrain, snow, equipment, technique, altitude, temperature, and physiology add uncertainty.
Common Questions
Why did an input disappear when I changed Solve for?
The hidden field is the requested output. Enter the remaining visible values and the calculator will solve for that target.
Will my last successful calculation be restored?
Yes, when browser storage is available. A successful Calculate saves a structured input snapshot; returning recomputes the result from that snapshot. Unsaved edits preserve the previous successful snapshot. Other scripts on this site may access browser storage. Reset clears this calculator’s saved data.

2024 Adult Compendium: winter activity codes 19150, 19160 and 19170 lists downhill skiing at 4.3, 6.3 and 8.0 MET during active time. The Compendium unit-conversion equation gives kcal/min = MET × 3.5 × kg ÷ 200. See the Adult Compendium scope for ages 19–59. The conventional formula and population MET values give approximate gross expenditure, not an individualized measurement.
