Key Takeaways
- Rowing MET values range from 3.5 (light ergometer / leisure on-water) to 12.0 (competitive / ≥200W erg) per the 2024 Compendium.[1]
- A 30-minute moderate erg session (7.0 MET) estimates approximately 257 kcal for a 70 kg person.[2]
- Competitive rowing (12.0 MET) is among the highest-MET activities in the Compendium.[1]
- Indoor ergometer wattage tiers provide a clear mapping between machine readout and MET value.
- These are informational estimates for personal journaling. Individual results vary.

On-Water Rowing
| Activity | MET | 55 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| Recreational Rowing | 3.5 | 101 | 129 | 156 | 184 |
| Moderate Rowing | 5.8 | 168 | 213 | 259 | 305 |
| Vigorous Rowing | 7 | 202 | 257 | 312 | 368 |
| Competitive Rowing | 12 | 347 | 441 | 536 | 630 |
How the Estimate Works
The calculator uses the standard MET formula with rowing-specific MET values from the 2024 Compendium:[1]
Calories = (MET × 3.5 × Wt_kg × Duration_min) ÷ 200
For indoor rowing, the ergometer wattage display maps directly to a MET tier. For on-water rowing, select the intensity matching your typical pace and effort level.

Stroke Rate Reference (Informational)
Stroke rate (strokes per minute, or SPM) is a common rowing metric. While this calculator uses wattage/intensity-based MET values, here is general context:
Light (16–20 SPM)
Warm-up or recovery pace. Lower power output per stroke.
Moderate (20–26 SPM)
Steady-state training range. Sustainable for longer sessions.
High (26–36+ SPM)
Race pace or interval intensity. Maximum power output.
