Calories burned
skindiving or scuba diving as a frogman
882 kcal / hour Skindiving or SCUBA diving as a frogman burns approximately 882 calories per hour for a 70 kg (154 lb) adult, and 441 calories in 30 minutes. Across the normal adult weight range the hourly figure runs from about 630 to 1,512 kcal.
It carries a MET value of 12 in the 2024 Adult Compendium of Physical Activities.

How this is worked out
- Take the MET value for skindiving or scuba diving as a frogman from the 2024 Adult Compendium of Physical Activities: MET 12.
- Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
- Multiply the rate by the number of minutes actually spent.
- Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200 kcal = kcal/min × minutes 12 × 3.5 × 70 ÷ 200 = 14.70 kcal/min 14.70 × 60 min = 882 kcal
Calories burned skindiving or scuba diving as a frogman 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) | 158 | 315 | 473 | 630 | 945 |
| 60 kg (132 lb) | 189 | 378 | 567 | 756 | 1,134 |
| 70 kg (154 lb) | 221 | 441 | 662 | 882 | 1,323 |
| 80 kg (176 lb) | 252 | 504 | 756 | 1,008 | 1,512 |
| 90 kg (198 lb) | 284 | 567 | 850 | 1,134 | 1,701 |

What 882 calories an hour actually means
At MET 12, skindiving or scuba diving as a frogman counts as very vigorous activity — it uses about 12 times the energy your body burns sitting still. For a 70 kg adult that works out to roughly 15 kcal per minute, or 882 kcal across a full hour.
Within occupation, that ranks 1st of 72 activities by energy cost — the highest in its group and above counter terrorism maneuvers (MET 9).
Put differently: one hour of skindiving or scuba diving as a frogman costs about the same energy as 180 minutes of ordinary walking.
On the food side, a slice of pizza (about 285 kcal) takes roughly 19 minutes of skindiving or scuba diving as a frogman 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.
A number this clean is a model. It does not know your gradient, your gear, the wind, or how hard you were actually trying.
Questions
How many calories does skindiving or scuba diving as a frogman burn per hour?
About 882 kcal per hour for a 70 kg (154 lb) adult, using the Compendium MET value of 12. A 90 kg adult burns closer to 1,134 kcal in the same hour, because energy cost scales almost directly with body mass.
How many calories does 30 minutes of skindiving or scuba diving as a frogman burn?
Roughly 441 kcal at 70 kg, 378 kcal at 60 kg and 630 kcal at 100 kg. Halving the time halves the calories — the relationship is linear.
What is the MET value of skindiving or scuba diving as a frogman?
12. One MET is the energy you use sitting quietly, so MET 12 means 12 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.
MET value from the 2024 Adult Compendium of Physical Activities (activity code 11495). Calories computed as MET × 3.5 × weight kg ÷ 200 per minute. General information only — not medical, fitness or nutrition advice. Calorie figures are population estimates and vary between individuals.
