Gardening MET Value: Official Values for Every Garden Task
Gardening MET values range from 1.5 (watering) to 5.0 (digging). Learn what MET means, official values from the Ainsworth Compendium, and how to calculate gardening calories.
Gardening MET values range from 1.5 for passive watering to 5.0 for heavy digging and tilling. General gardening tasks like planting and mulching carry a MET of 3.5, placing them in the moderate-intensity exercise category alongside brisk walking.
Use the Gardening Calorie Calculator to calculate your personalized calorie burn based on your activity type and body weight.
What Is a MET Value?
MET stands for Metabolic Equivalent of Task. It is a standardized measure of the energy cost of physical activities, expressed as a multiple of resting metabolic rate.
- MET 1.0 = sitting at rest (your baseline)
- MET 2.0 = activity that burns twice as many calories as sitting still
- MET 3.5 = general gardening (burns 3.5× more calories than sitting)
- MET 4.5 = active digging (burns 4.5× more calories than sitting)
A MET of 3.0 or higher is classified as moderate-intensity exercise by major health organizations including the WHO and the American College of Sports Medicine.
The formula to convert MET values into calories burned:
Calories = MET × Weight (kg) × Duration (hours)
Official Gardening MET Values
All values below are sourced from the Ainsworth Compendium of Physical Activities — the definitive scientific reference for MET values, used by researchers, clinicians, and public health agencies worldwide.
| Gardening Activity | MET Value | Intensity Level |
|---|---|---|
| Watering lawn or garden (standing) | 1.5 | Very light |
| Watering (walking with hose) | 2.0 | Light |
| Weeding (light, surface level) | 3.0 | Light-moderate |
| General gardening, planting | 3.5 | Moderate |
| Raking lawn | 4.0 | Moderate |
| Bagging grass/leaves | 4.0 | Moderate |
| Mulching, applying compost | 4.0 | Moderate |
| Digging, spading garden beds | 4.5 | Moderate-vigorous |
| Tilling soil (manual) | 5.0 | Vigorous |
| Hauling soil and heavy materials | 5.0 | Vigorous |
| Heavy landscaping | 5.5–6.0 | Vigorous |
Gardening MET vs Related Activities
How do gardening tasks compare to other common physical activities in terms of MET values?
| Activity | MET Value | Category |
|---|---|---|
| Sitting quietly | 1.0 | Sedentary |
| Light housework | 2.5 | Light |
| Yoga (hatha) | 2.5 | Light |
| Light Gardening (weeding, watering) | 3.0 | Light-moderate |
| Brisk walking (5 km/h) | 3.5 | Moderate |
| General Gardening (planting) | 3.5 | Moderate |
| Lawn mowing (push, power) | 4.0 | Moderate |
| Heavy Gardening (digging) | 4.5 | Moderate-vigorous |
| Snow shoveling (light) | 5.0 | Vigorous |
| Tilling soil (manual) | 5.0 | Vigorous |
| Snow shoveling (general) | 6.0 | Vigorous |
| Running (8 km/h) | 8.5 | Very vigorous |
| Snow shoveling (heavy) | 7.0 | Vigorous |
General gardening sits exactly alongside brisk walking at MET 3.5. Heavy digging matches power walking and light aerobics. This makes gardening one of the few household activities that genuinely reaches exercise-equivalent intensity.
Calories Burned Gardening by MET Value
Using the formula (Calories = MET × Weight × Duration), here are calories burned for common MET values across a range of body weights at 60 minutes:
| MET | Activity Example | 60 kg | 70 kg | 80 kg | 90 kg |
|---|---|---|---|---|---|
| 1.5 | Watering (standing) | 90 | 105 | 120 | 135 |
| 3.0 | Light weeding | 180 | 210 | 240 | 270 |
| 3.5 | General gardening | 210 | 245 | 280 | 315 |
| 4.0 | Raking, mulching | 240 | 280 | 320 | 360 |
| 4.5 | Digging beds | 270 | 315 | 360 | 405 |
| 5.0 | Tilling soil | 300 | 350 | 400 | 450 |
How Accurate Is the MET Formula for Gardening?
The MET formula gives a solid population-average estimate. Research comparing MET-predicted calorie burn to laboratory measurements (using indirect calorimetry) typically finds accuracy within ±20–30% for moderate activities like gardening.
Factors that create real-world variation from the MET estimate:
Body composition: MET values are calibrated to average body composition. Individuals with higher muscle mass may burn slightly more; those with lower muscle mass may burn slightly less.
Work efficiency: Experienced gardeners tend to work more efficiently than beginners — achieving the same garden output with less wasted motion and energy. A beginner may burn more calories than predicted for the same visible output.
Soil and terrain: Rocky, clay-heavy, or waterlogged soil requires substantially more force to dig than the "standard" conditions assumed in Compendium MET values. Sloped terrain also increases energy cost.
Tool type: The Compendium values assume manual tool use. Motorised equipment (electric tillers, petrol cultivators) dramatically reduces the MET value of the corresponding task.
Temperature: Exercising in hot weather increases cardiovascular strain and may raise effective calorie burn by 5–15%.
Using MET to Plan Your Garden Workout
If you have a specific calorie goal for a gardening session, you can rearrange the MET formula to find the required duration:
Duration (hours) = Calorie Goal ÷ (MET × Weight in kg)
Example: 70 kg person wants to burn 300 calories through digging (MET 4.5)
300 ÷ (4.5 × 70) = 300 ÷ 315 = 0.95 hours ≈ 57 minutes
That same person would need 86 minutes of light weeding (MET 3.0) to burn the same 300 calories:
300 ÷ (3.0 × 70) = 300 ÷ 210 = 1.43 hours ≈ 86 minutes
Choosing higher-MET tasks is the most efficient way to use gardening time for calorie expenditure.
