Depending on the measuring instruments used, different sets of equations for the calculation of the density of air can be applied. Air is a mixture of gases and the calculations always simplify, to a greater or lesser extent, the properties of the mixture.

Hence the mass per unit volume of the gas (its density) decreases. 3266: 3041:{\displaystyle \rho =\rho _{0}e^{\left({\frac {gM}{RL}}-1\right)\ln \left(1-{\frac {Lh}{T_{0}}}\right)}\approx \rho _{0}e^{-\left({\frac {gM}{RL}}-1\right){\frac {Lh}{T_{0}}}}=\rho _{0}e^{-\left({\frac {gMh}{RT_{0}}}-{\frac {Lh}{T_{0}}}\right)}} 5567:
