Stefan–Boltzmann Law (Radiated Power)
P = ε·σ·A·T^4
What it says
Total power radiated by a body as a function of its emissivity, surface area, and absolute temperature.
Symbols
| Symbol | Quantity | Dimension |
|---|---|---|
P | Radiated power (W) | M L^2 T^-3 |
ε | Emissivity (dimensionless) | 1 |
σ | Stefan-Boltzmann constant (5.670374419e-8 W/(m^2·K^4)) | M T^-3 Θ^-4 |
A | Surface area (m^2) | L^2 |
T | Absolute temperature (K) | Θ |
