Description
At standard temperature and pressure dry (STPD: 0 °C = 273.15 K and 1 atm = 101.325 kPa = 760 mmHg), the molar volume of an ideal gas, V_{m}, and V_{m,O2} is 22.414 and 22.392 L∙mol^{-1}, respectively. Rounded to three decimal places, both values yield the conversion factor of 0.744 from units used in spiroergometry (V_{O2max} [mL O_{2}·min^{-1}]) to SI units [µmol O_{2}·s^{-1}]. For comparison at normal temperature and pressure dry (NTPD: 20 °C), V_{m,O2} is 24.038 L∙mol^{-1}. Note that the SI standard pressure is 100 kPa, which corresponds to the standard molar volume of an ideal gas of 22.711 L∙mol^{-1} and 22.689 L∙mol^{-1} for O_{2}.
