Calories burned
boating
140 kcal / hour Boating burns approximately 140 calories per hour for a 70 kg (154 lb) adult, and 70 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 100 to 239 kcal.
It carries a MET value of 1.9 in the 2024 Adult Compendium of Physical Activities, which lists 2 measured variations of this activity from MET 1.3 to 2.5.
Calories burned boating 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) | 25 | 50 | 75 | 100 | 150 |
| 60 kg (132 lb) | 30 | 60 | 90 | 120 | 180 |
| 70 kg (154 lb) | 35 | 70 | 105 | 140 | 209 |
| 80 kg (176 lb) | 40 | 80 | 120 | 160 | 239 |
| 90 kg (198 lb) | 45 | 90 | 135 | 180 | 269 |
| 100 kg (220 lb) | 50 | 100 | 150 | 200 | 299 |
| 110 kg (243 lb) | 55 | 110 | 165 | 219 | 329 |
| 120 kg (265 lb) | 60 | 120 | 180 | 239 | 359 |

Every official intensity of boating
The Compendium lists 2 separate boating entries, each with its own measured MET value — from 1.3 to 2.5. 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 |
|---|---|---|---|---|
| power, passenger, light | 1.3 | 96 | 123 | 18012 |
| power, driving | 2.5 | 184 | 236 | 18010 |
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 140 calories an hour actually means
At MET 1.9, boating counts as light activity — it uses about 1.9 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 2 kcal per minute, or 140 kcal across a full hour.
Within water activities, that ranks 29th of 29 activities by energy cost, a little below tubing (MET 2.3).
Put differently: one hour of boating costs about the same energy as 28 minutes of ordinary walking.
On the food side, a chocolate bar (about 235 kcal) takes roughly 101 minutes of boating 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 boating burn per hour?
About 140 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 1.9. A 90 kg adult burns closer to 180 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of boating burn?
Roughly 70 kcal at 70 kg, 60 kcal at 60 kg and 100 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of boating?
1.9, taken as the median of the 2 boating entries in the 2024 Adult Compendium, which range from 1.3 to 2.5 depending on intensity. One MET is the energy you use sitting quietly, so MET 1.9 means 1.9 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.
