Instructions:
On the left: Enter the temperature in kelvins (K) and the emissivity. Then click Find F. The program will calculate the flux density according to the Stefan-Boltzmann law.
On the right: Enter the flux density is watts per square meter (W m-2) and the emissivity. Then click Find T. The program will find the temperature by inverting the Stefan-Boltzmann law.
Click Reset to start over.
