Calories burned
hauling water
331 kcal / hour Hauling water burns approximately 331 calories per hour for a 70 kg (154 lb) adult, and 165 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 236 to 567 kcal.
It carries a MET value of 4.5 in the 2024 Adult Compendium of Physical Activities.
Calories burned hauling water 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) | 59 | 118 | 177 | 236 | 354 |
| 60 kg (132 lb) | 71 | 142 | 213 | 284 | 425 |
| 70 kg (154 lb) | 83 | 165 | 248 | 331 | 496 |
| 80 kg (176 lb) | 95 | 189 | 284 | 378 | 567 |
| 90 kg (198 lb) | 106 | 213 | 319 | 425 | 638 |
| 100 kg (220 lb) | 118 | 236 | 354 | 473 | 709 |
| 110 kg (243 lb) | 130 | 260 | 390 | 520 | 780 |

What 331 calories an hour actually means
At MET 4.5, hauling water counts as moderate activity — it uses about 4.5 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 6 kcal per minute, or 331 kcal across a full hour.
Within walking, that ranks 13th of 28 activities by energy cost, a little below hiking or walking at a normal pace through… (MET 5.3) and above using medical knee scooter (MET 4.3).
Put differently: one hour of hauling water costs about the same energy as 68 minutes of ordinary walking.
On the food side, a chocolate bar (about 235 kcal) takes roughly 43 minutes of hauling water 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 hauling water burn per hour?
About 331 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 4.5. A 90 kg adult burns closer to 425 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of hauling water burn?
Roughly 165 kcal at 70 kg, 142 kcal at 60 kg and 236 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of hauling water?
4.5. One MET is the energy you use sitting quietly, so MET 4.5 means 4.5 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.
