 | | A temperature given in kelvins, without further qualification, is measured with respect to absolute zero, where molecular motion stops (except for the residual quantum mechanical zero-point energy). |
 | | It is also common to give a temperature relative to the Celsius temperature scale, with a reference temperature of 0° C = 273.15 K, approximately the melting point of water under ordinary conditions. |
 | | The temperature of equilibrium electromagnetic radiation, a system of photons, is determined by the energy intensity, as given by Planck's flbody distribution law. |
