A diffusion coefficient of the heat transfer in a given medium:

(1)	$\begin{array}{l}\displaystyle a = \frac{\lambda}{\rho \, c_p}\end{array}$

where

$\begin{array}{l}\lambda\end{array}$	Thermal Conductivity of the medium
$\begin{array}{l}c_p\end{array}$	Isobaric specific heat capacity of the medium
$\begin{array}{l}\rho\end{array}$	density of the of the medium

Symbol	Dimension	SI units	Oil metric units	Oil field units
$\begin{array}{l}a\end{array}$	L²T⁻¹	m^2/s	m^2/s
