The emissivity coefficient - ε - indicates the radiation of heat from a body according the Stefan-Boltzmann Law, compared with the radiation of heat from a ideal black body where the emissivity coefficient ε = 1.
The emissivity coefficient - ε - for some common materials can be found in the table below:
| Material | Emissivity
Coefficient - ε - |
| Water | 0.993 - 0.998 |
| Ice | 0.98 |
| Snow | 0.969 - 0.997 |
| Sand | 0.949 - 0.962 |
| Granite | 0.898 |
| Green Grass | 0.975 - 0.986 |
