Snow Shoveling Calorie Formula Explained
Learn the exact formula used to calculate calories burned shoveling snow. Includes MET values, step-by-step examples, and worked calculations by body weight.
The snow shoveling calorie formula is: Calories = MET × weight (kg) × duration (hours). This is the same MET-based method used by the WHO, CDC, and American College of Sports Medicine to estimate exercise energy expenditure.

The Formula
Calories (kcal) = MET × Weight (kg) × Duration (hours)
What Each Variable Means
- MET (Metabolic Equivalent of Task): A measure of exercise intensity as a multiple of your resting metabolic rate. MET 1.0 = sitting still. MET 6.0 = burning energy at six times your resting rate.
- Weight in kg: Your body mass in kilograms. If you know your weight in pounds, divide by 2.205 to convert.
- Duration in hours: Time spent actively shoveling. Convert minutes by dividing by 60 (e.g., 30 minutes = 0.5 hours).
MET Values for Snow Shoveling
Snow shoveling MET values come from the Ainsworth Compendium of Physical Activities — the gold standard reference used in exercise science research worldwide.
| Snow Type | Effort Level | MET Value |
|---|---|---|
| Light powder / dusting | Low effort | 5.0 |
| Moderate / average snowfall | General shoveling | 6.0 |
| Heavy, wet, packed snow | Vigorous effort | 7.0 |

Step-by-Step Example Calculations
Example 1: Light Snow, 20 Minutes, 70 kg Person
- Select MET: Light snow → MET 5.0
- Weight: 70 kg
- Duration: 20 minutes → 20 ÷ 60 = 0.333 hours
- Calculate: 5.0 × 70 × 0.333 = 117 calories
Example 2: Moderate Snow, 30 Minutes, 80 kg Person
- Select MET: Moderate snow → MET 6.0
- Weight: 80 kg
- Duration: 30 minutes → 30 ÷ 60 = 0.5 hours
- Calculate: 6.0 × 80 × 0.5 = 240 calories
Example 3: Heavy Wet Snow, 45 Minutes, 90 kg Person
- Select MET: Heavy wet snow → MET 7.0
- Weight: 90 kg
- Duration: 45 minutes → 45 ÷ 60 = 0.75 hours
- Calculate: 7.0 × 90 × 0.75 = 473 calories
Converting Pounds to Kilograms
If your weight is in pounds:
Weight (kg) = Weight (lbs) ÷ 2.205
| Pounds | Kilograms |
|---|---|
| 120 lbs | 54.4 kg |
| 140 lbs | 63.5 kg |
| 154 lbs | 69.9 kg |
| 175 lbs | 79.4 kg |
| 200 lbs | 90.7 kg |
| 220 lbs | 99.8 kg |
What the Formula Measures
The MET formula calculates gross calorie expenditure — your total energy output including your resting metabolic rate. This is the same number shown on fitness trackers and exercise equipment, and the standard way calorie burn is reported in fitness contexts.
If you want your net calorie burn (exercise calories only, excluding what you'd burn at rest), subtract your resting calorie rate:
Net Calories = Gross Calories − (1.0 × weight_kg × duration_hours)
For most practical purposes (workout tracking, calorie counting), the gross figure is what you need.
Accuracy and Limitations
MET values are population averages derived from laboratory studies. They produce reliable estimates for most adults but do not account for:
- Individual fitness level (fitter people burn calories more efficiently)
- Shovel weight and type
- Rest breaks during the session
- Exact snow conditions (MET categories are approximations)
Real-world calorie burn typically varies ±15–20% around MET-based estimates. For most tracking purposes, this level of accuracy is more than sufficient.
