DiveCalcs

DiveCalcs is a powerful tool designed to simplify key calculations used in recreational dive planning. Whether you're preparing for your next dive or learning the fundamentals of dive theory, DiveCalcs helps you understand the how and why behind every calculation.

Explore clear, easy-to-use tools such as:

Gas Consumption

• SAC (Surface Air Consumption): Estimate your surface-equivalent air consumption and determine the gas needed for any dive based on your personal usage.

• Dive Time: Calculate how long your gas supply will last under specific conditions.

Nitrox Tools

• MOD (Maximum Operating Depth): Determine safe depth limits based on gas mix and target depth.

• EAD (Equivalent Air Depth): Calculate equivalent air depth to apply standard NDL tables while using Nitrox.

• Best Mix: Automatically find the best Nitrox blend for your planned depth.

• NDL (No-Decompression Limit): Estimate how long you can remain at depth without incurring required decompression stops.

NDL Calculator Disclaimer:
This tool is for illustrative and educational purposes only. It does not account for real-world dive profiles, ascent/descent rates, or on/off-gassing behavior. It is not a substitute for certified dive computers or dive tables. Based on Bühlmann ZH-L16C.

Additional Tools

• Pressure at Depth: View absolute and gauge pressure at any depth.

• Weight Calculator: Estimate recommended weighting for proper buoyancy based on body characteristics and dive configuration.
