Estimate gross calories, active skiing duration, or equation-implied body weight using the 2024 Adult Compendium’s light, moderate, and vigorous skiing 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
The selected output is hidden, disabled, cleared, and made non-required. Only the source values needed for that mode remain visible.
How to Use This Calculator
- Select the result you want in the Solve for menu.
- Enter only the visible source values and their explicit units.
- Select Calculate and review the estimate and substituted steps.
- Use Reset before starting a different scenario.
Worked Example
At 6.3 MET, a 70 kg person skiing for 60 active minutes has an estimated gross expenditure of 463.1 kcal.
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 planning or consistent comparisons. It is not a direct measurement and may differ from a wearable or laboratory result.
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. The calculator saves enabled source values and the successful result in this browser. Reset clears that saved state.
