Understanding Heat Flux Density
Heat flux density (or heat flux, or thermal flux) is the rate of heat energy transfer through a given surface per unit area. It quantifies the intensity of heating or cooling at a surface.
The SI unit for heat flux density is Watts per square meter (W/m²).
| Unit Name | Symbol | Relation to W/m² (Approx.) |
|---|---|---|
| Watt/square meter | W/m² | Base unit (1 W/m²) |
| Kilowatt/square meter | kW/m² | 1000 W/m² |
| Watt/square centimeter | W/cm² | 10000 W/m² |
| Btu (IT)/hour/square foot | BtuIT/(h·ft²) | 3.1546 W/m² |
| Calorie (IT)/second/square centimeter | calIT/(s·cm²) | 41868 W/m² |
| Kilocalorie (IT)/hour/square meter | kcalIT/(h·m²) | 1.163 W/m² |
