The Stefan number[1] (St or Ste) is defined as the ratio of sensible heat to latent heat. It is given by the formula

\mathrm{Ste} = \frac{c_p \Delta T}{L},

where

It is a dimensionless parameter that is useful in analyzing a Stefan problem. The parameter was developed from Josef Stefan's calculations of the rate of phase change of water into ice on the polar ice caps.
