6,119.063W/m²
That's 1.85× as hot as a person, while a bulb filament is 4.7× hotter. It radiates about 6,119 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 °C to W/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 °C = 6,119.06 W/m².
