&lt;br /&gt;
The &#039;&#039;&#039;molecular-scale temperature&#039;&#039;&#039; is the defining property of the [[U.S. Standard Atmosphere#1962 version|U.S. Standard Atmosphere, 1962]]. It is  defined by the relationship:&lt;br /&gt;
&lt;br /&gt;
: &amp;lt;math&amp;gt;T_m(z)=\frac{M_0}{M(z)}\cdot{T(z)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
: &#039;&#039;T&amp;lt;sub&amp;gt;m&amp;lt;/sub&amp;gt;(z)&#039;&#039; is molecular-scale temperature at [[altitude]] &#039;&#039;z&#039;&#039;;&lt;br /&gt;
: &#039;&#039;M&amp;lt;sub&amp;gt;0&amp;lt;/sub&amp;gt;&#039;&#039; is [[molecular mass|molecular weight]] of air at [[sea level]];&lt;br /&gt;
: &#039;&#039;M(z)&#039;&#039; is molecular weight of air at altitude &#039;&#039;z&#039;&#039;;&lt;br /&gt;
: &#039;&#039;T(z)&#039;&#039; is [[Thermodynamic temperature|absolute temperature]] at altitude &#039;&#039;z&#039;&#039;.&lt;br /&gt;
