Convert moles to liters and liters to moles

This online calculator converts to moles given liters of a gas at STP and converts to liters of a gas at STP given moles

This online calculator converts moles to liters of a gas at STP (standard temperature and pressure) and liters of gas to moles. The conversion is straightforward and is based on the fact that the ideal gas equation is a good approximation for many common gases at standard temperature and pressure.

Thus, we can rearrange terms in ideal gas equation and write them like this \frac{V}{n}=\frac{RT}{P}

The relation \frac{V}{n} is the molar volume V_m.

Hence, for a given temperature and pressure, the molar volume is the same for all ideal gases and is known to the same precision as the gas constant: R = 0.082 057 338(47) L atm K−1 mol−1, that is a relative standard uncertainty of 5.7×10−7, according to the 2014 CODATA recommended value1

The molar volume of an ideal gas at standard temperature and pressure (273.15 K, 101.325 kPa) is 22.413 962 x 10-3 m3 mol-1 with standard uncertainty of 0.000013 x 10-3 m3 mol-12

The calculator below uses the formula n=\frac{V}{V_m} to convert liters to moles and V=n*V_m to convert moles to liters, where V_m is 22.413962
