Which temperature scale to useYou open an astronomy book and encounter the equation (light emitted) = (constant) × T4 for the light emitted by a star as a function of its surface temperature. What temperature scale is implied? The equation tells us that doubling the temperature results in the emission of 16 times as much light. Such a ratio only makes sense if the Kelvin scale is used.
