Air Usage Calculator

This Air Usage Calculator for Scuba Divers is based on the BSAC recommended method for calculating the air used on a given dive. It assumes a 'square profile' dive (ie worst case) where you breathe at the maximum rate at depth all through the dive. Please note that this is a planning tool and should be based on a realistic breathing rate at the surface (BSAC recommend 25 litres/minute for diving in UK waters). The resulting bottom time should be used as a planning guideline, and the user must be personally responsible for monitoring air usage during the dive.

Instructions: Type the values into the first four cells for your tank size, pressure, and the planed depth and reserve; then press calculate, and the mathematical forecast will be produced. Remember that this is a planning tool and it better to be conservative with estimates to improve your safety margins. Every time you press calculate the figures will be updated.
