OVM Dive Mixer — Gas Mix & Fill Calculator

Tank Fill Calculator (Boost)

Calculate the final pressure when filling from a donor tank to a target tank.

Donor Tank Volume (L): Donor Tank Pressure (bar): Target Tank Volume (L): Target Tank Starting Pressure (bar):

Calculate the resulting gas mix composition after topping off with a different gas.

O₂ (%): He (%): Starting Pressure (bar):

O₂ (%): He (%):

Final Pressure (bar):

Calculate the required pressures for O₂, He, and air to achieve a target trimix starting from an initial mix.

Desired O₂ (%): Desired He (%): Target Final Pressure (bar):

Current Pressure (bar): Current O₂ (%): Current He (%):
