			A '''heat current''' is a kinetic exchange rate between [[molecule]]s, relative to the material in which the [[Kinematics\|kinesis]] occurs. It is defined as <math>\frac{dQ}{dt}</math>, where <math>Q</math> is [[heat]] and <math>t</math> is [[time]].

			For [[Conduction (heat)\|conduction]], heat current is defined by [[Fourier's law]] as
			: <math> \frac{\partial Q}{\partial t} = -k \oint_S{\overrightarrow{\nabla} T \cdot \,\overrightarrow{dS}} </math>
			where
			:<math>\big. \frac{\partial Q}{\partial t}\big.</math> is the amount of heat transferred per unit time [W] and
			:
			:<math>\overrightarrow{dS}</math> is an oriented surface area element [m<sup>2</sup>]
			The above [[differential equation]], when [[Integral\|integrated]] for a homogeneous material of 1-D geometry between two endpoints at constant temperature, gives the heat flow rate as:
			: <math> \big. \frac{\Delta Q}{\Delta t} = -k A \frac{\Delta T}{\Delta x} </math>
			where
			: ''A'' is the cross-sectional surface area,
			: <math>\Delta T</math> is the temperature difference between the ends,
			: <math>\Delta x</math> is the distance between the ends.

			For [[thermal radiation]], heat current is defined as

			where the [[constant of proportionality]] <math>\sigma</math> is the [[Stefan–Boltzmann constant]], <math>A</math> is the radiating surface area, and <math>T</math> is temperature.
