NOTE: Standard Conditions (STP) using metric units are given. Changing units requires you to change these values if you wish to use them. Output will be in metric (kg & m3) and U.S. customary (lb & ft3) units. Gauge pressures assume standard atmospheric pressure (101.325 kPa).

Molecular weight input field takes precedence over gas presets. Clear field if you wish to switch to a preset.

This serves as nothing more than a pretty front end for the Ideal Gas Law: ρ = (P * M.W.) / (R * T)
