# Heat Flux Density Converter

Table of Contents:

Heat flux or thermal flux is the rate of heat energy transfer through a given surface. The measurement of heat flux is most often done by measuring a temperature difference over a piece of material with known thermal conductivity.

Heat rate is a scalar quantity, while heat flux is a vectorial quantity. To define the heat flux at a certain point in space, one takes the limiting case where the size of the surface becomes infinitesimally small.

The flux of electric and magnetic field lines is frequently discussed in electrostatics. This is because Maxwell's equations in integral form involve integrals like above for electric and magnetic fields. Heat, a form of kinetic energy, is transferred in three ways: conduction, convection, and radiation. Heat transfer (also called thermal transfer) can occur only if a temperature difference exists, and then only in the direction of decreasing temperature.

**Example:**
