All thermodynamic properties require absolute temperature. Convert Fahrenheit to Rankine by adding the offset constant. See physics::conversions::kFahrenheitToRankineOffset for the conversion constant.

\begin{equation}\label{eq:gas-flue-gas-material-temp-conv-cpp} T_{abs} = T_{F} + 460\end{equation}

Symbols

\(T_{abs}\)	Absolute temperature \([\unit{ \degreeRankine}]\)
\(T_{F}\)	Temperature in Fahrenheit \([\unit{ \degreeFahrenheit}]\)
\(460\)	Fahrenheit to Rankine offset - see physics::conversions::kFahrenheitToRankineOffset \([\unit{ \degreeRankine}]\)
