Gas partial pressure at depth

Explanation Marine Deep's explanation, not a requirement.

Partial pressure = fraction of the gas in the mix × absolute pressure at depth (see the depth to pressure calculator). The result is a number only: the tool says nothing about whether a mix is suitable at that depth.

Not a dive planning tool. This calculator does arithmetic only. It does not plan dives, compute decompression, no-stop limits, gas endurance or maximum operating depths, and it does not check anything against any rule or limit. Use your company's procedures, approved tables and the applicable regulations for all of those.
