Snorkeling / scuba diving calorie chart
Estimated kcal for snorkeling / scuba diving (MET 7) by session length and body weight. Values are rounded estimates.
| Duration | 50 kg | 60 kg | 70 kg | 85 kg | 100 kg |
|---|---|---|---|---|---|
| 10 min | 58 | 70 | 82 | 99 | 117 |

| 45 min | 263 | 315 | 368 | 446 | 525 |
| 1 h | 350 | 420 | 490 | 595 | 700 |
| 1.5 h | 525 | 630 | 735 | 893 | 1050 |
Imperial check: 154 lb ≈ 70 kg · 187 lb ≈ 85 kg · 220 lb ≈ 100 kg.
About this estimate
Snorkeling / scuba diving carries a MET of 7(vigorous intensity) in the Compendium of Physical Activities — the research standard for energy-cost data (source database, see also our full methodology). The calculator uses:
calories = MET × weight (kg) × hours
So for a 70 kg person, one hour of snorkeling / scuba diving costs about490 kcal. Effort matters: going harder, adding hills, carrying load or rushing intervals all push the real number up; breaks and easy pacing pull it down.
How to burn more
- Add intervals — 1 minute hard, 2 minutes easy — to raise average intensity.
- Extend the session gradually; an extra 10 minutes adds ~82 kcal at 70 kg.
- Combine with a second activity — see the compare tray in the calculator above.
- Keep non-exercise movement high on rest days (walking, stairs, chores).
Estimate only — not medical advice. Real-world burn depends on fitness, body composition, age, weather and terrain.
