Key Takeaways
- Mowing MET values range from 2.5 (riding mower) to 6.0 (hand reel mower) per the 2024 Compendium.[1]
- A 30-minute walk-behind power mower session estimates approximately 202 kcal for a 70 kg person.[2]
- Using a hand reel mower burns about 2.4× the calories of a riding mower for the same duration.[1]
- Sloped or hilly terrain adds approximately 15% to the calorie estimate.
- These are informational estimates for personal journaling. Individual results vary with conditions.

Sloped / Hilly Terrain (+15%)
| Mower Type | MET | 55 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| Riding Mower | 2.88 | 83 | 106 | 128 | 151 |
| Power Mower (Light) | 5.17 | 149 | 190 | 231 | 272 |

How the Estimate Works
The calculator uses the standard MET formula from the 2024 Compendium, with an optional terrain modifier:[1]
Calories = (MET × Terrain_multiplier × 3.5 × Wt_kg × Duration_min) ÷ 200
The terrain modifier is a transparent adjustment: flat = 1.0×, sloped/hilly = 1.15×. This approximation accounts for the additional effort of pushing a mower up inclines.
