Calories burned
rowing
809 kcal / hour Rowing burns approximately 809 calories per hour for a 70 kg (154 lb) adult, and 404 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 578 to 1,386 kcal.
It carries a MET value of 11 in the 2024 Adult Compendium of Physical Activities, which lists 7 measured variations of this activity from MET 5 to 15.5.
Calories burned rowing by body weight
Energy cost scales with the mass you move, so body weight changes the answer more than anything else.
| Body weight | 15 min | 30 min | 45 min | 60 min | 90 min |
|---|---|---|---|---|---|
| 50 kg (110 lb) | 144 | 289 | 433 | 578 | 866 |
| 60 kg (132 lb) | 173 | 347 | 520 | 693 | 1,040 |
| 70 kg (154 lb) | 202 | 404 | 606 | 809 | 1,213 |
| 80 kg (176 lb) | 231 | 462 | 693 | 924 | 1,386 |
| 90 kg (198 lb) | 260 | 520 | 780 | 1,040 | 1,559 |
| 100 kg (220 lb) | 289 | 578 | 866 | 1,155 | 1,733 |
| 110 kg (243 lb) | 318 | 635 | 953 | 1,271 | 1,906 |

Every official intensity of rowing
The Compendium lists 7 separate rowing entries, each with its own measured MET value — from 5 to 15.5. Most calculators collapse all of this into one number. Pick the row that matches what you actually did.
| Variation | MET | kcal/hr at 70 kg | kcal/hr at 90 kg | Code |
|---|---|---|---|---|
| stationary ergometer, general, <100 watts, moderate effort | 5 | 368 | 473 | — |
| stationary ergometer, general, vigorous effort | 7.3 | 537 | 690 | — |
| stationary, 100 to 149 watts, vigorous effort | 7.5 | 551 | 709 | 02072 |
| stationary, 150 to 199 watts, vigorous effort | 11 | 809 | 1,040 | 02074 |
| stationary, 200 watts, very vigorous effort | 14 | 1,029 | 1,323 | 02080 |
| simulated crew in a water tank, single oar, 33 strokes/min, | 15.5 | 1,139 | 1,465 | 18112 |
| single scull, ergometer, ergometer on slides, racing speed (32+ strokes/min, >10 mph) | 15.5 | 1,139 | 1,465 | 18114 |
Codes are 2024 Adult Compendium activity codes. A dash means the code could not be read unambiguously from the published table, so it is left blank rather than guessed — the MET value and description are unaffected.
What 809 calories an hour actually means
At MET 11, rowing counts as very vigorous activity — it uses about 11 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 13 kcal per minute, or 809 kcal across a full hour.
Within conditioning exercise, that ranks 4th of 53 activities by energy cost, a little below blackbox immersive virtual reality exergaming… (MET 13) and above slide board exercise (MET 10.5).
Put differently: one hour of rowing costs about the same energy as 165 minutes of ordinary walking.
On the food side, a medium banana (about 105 kcal) takes roughly 8 minutes of rowing to offset at that body weight. That framing is useful for scale, but it is worth saying plainly: exercise and diet are not a ledger that cancels neatly, and appetite tends to rise with activity.
Questions
How many calories does rowing burn per hour?
About 809 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 11. A 90 kg adult burns closer to 1,040 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of rowing burn?
Roughly 404 kcal at 70 kg, 347 kcal at 60 kg and 578 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of rowing?
11, taken as the median of the 7 rowing entries in the 2024 Adult Compendium, which range from 5 to 15.5 depending on intensity. One MET is the energy you use sitting quietly, so MET 11 means 11 times that rate.
Is this an exact number of calories?
No, and no calculator can give you one. MET values are population averages measured in laboratory conditions; your own figure varies with fitness, technique, terrain, temperature and body composition. Treat these numbers as a solid estimate for planning, not a precise measurement — and treat any device or site claiming three-digit precision with suspicion.
