SCUBA-DIVING Utilities
Choose a specialized option to begin instant real-time conversion.
Gas mix — O2 % ↔ depth limit — MOD calculation
Calculate the Maximum Operating Depth (MOD) and partial pressure of oxygen (PPO2) for nitrox and air diving.
Tank pressure ↔ volume ↔ dive time — SAC rate
Calculate Surface Air Consumption (SAC) rate, gas consumption, and remaining dive time based on cylinder volume and depth.
Decompression stop — depth + time → stop obligation
Estimate decompression stop obligations, no-decompression limits (NDL), and ceiling depths based on depth and bottom time.
Buoyancy — weight needed ↔ wetsuit thickness + water type
Determine required lead weight adjustments based on wetsuit thickness, water density (salt vs. fresh), and diver body metrics.
Visibility — Secchi depth ↔ water clarity rating
Estimate underwater horizontal visibility and water quality indices using standard Secchi disk depth readings.
Narcosis depth — nitrogen % ↔ equivalent air depth
Calculate Equivalent Narcotic Depth (END) and Equivalent Air Depth (EAD) for nitrox and trimix gas breathing mixtures.
