Kelvin to kilowatts per square meter
Type a value in K to get it in kW/m² instantly.
0.4593kW/m²
That's 1.04× as hot as the Earth’s surface, while a person is 1.03× hotter. It radiates about 459.3 W from every square meter.
What it means
How much does it radiate?
These are for a perfect black body. A real surface radiates its emissivity times as much — around 0.95 for skin and paint, 0.05 for polished metal.
The math
How to convert K to kW/m²
Two laws at once: W/m² = 5.670 × 10⁻⁸ × T⁴ for the power, and peak nm = 2,897,772 ÷ T for the color.
Example: 300 K = 0.4593 kW/m².
