Scuba Weight Calculator

Estimate starting weight for scuba diving.

Estimated weight 8

Estimated weight 17.637

Formula: weight ≈ body weight × 8–10%

Step-by-step with your numbers:

1. Values used:

2. Body weight = 80

3. Water type = 0.1

5. Estimated weight = Body weight x Water type = 80 x 0.1 = 8

6. Estimated weight = 17.637

Did we solve your problem today?

A rough starting point for dive weighting — always confirm with a buoyancy check.

The math behind it

weight ≈ body weight × ~10% (saltwater) or ~8% (freshwater). Wetsuit thickness changes it.

80 kg in saltwater → ~8 kg.

Exact?

Do a proper buoyancy check in the water — this is only a starting estimate.
