stefan boltzmann constant

stefan boltzmann constant

The Stefan Boltzmann constant is a frequently used natural constant in physics. It is used to quantify the relationship between temperature and energy flux for a radiating blackbody. Energy flux may seem like a word reserved for science fiction movies, but it's definition is rather simple. Flux merely refers to the amount of energy that passes through a given area over time. One can calculate the energy flux for a radiating blackbody by taking the product of the Stefan Boltzmann Constant and the absolute temperature raised to the fourth power. However, one important note is that temperature must be taken on an absolute scale. In science and physics, Centigrade is the preferred unit of measurement for temperature; although on an absolute scale, one must use Kelvin. Zero on the Kelvin scale is set at absolute zero, so to convert between units, one adds 273.15 degrees to the measurement in Celsius.
