# Molecular-scale temperature

The molecular-scale temperature is the defining property of the U.S. Standard Atmosphere, 1962. It is defined by the relationship:

${\displaystyle T_{m}(z)={\frac {M_{0}}{M(z)}}\cdot {T(z)}}$
Tm(z) is molecular-scale temperature at altitude z;
M0 is molecular weight of air at sea level;
M(z) is molecular weight of air at altitude z;
T(z) is absolute temperature at altitude z.
