About these units
The btu per hour square foot (BTU/(h·ft²)) is an imperial unit of heat flux density, equal to 3.1545907 watts per square meter.
The kilowatt per square meter (kW/m²) is a metric unit of heat flux density, equal to 1,000 watts per square meter.
Going the other way, 1 kilowatt per square meter = 316.99833 btu per hour square foot. Heat flux density is power per unit area: the heat escaping through a wall, the output of a radiant panel, or sunlight on a roof, which peaks near 1,000 W/m². Building services engineers switch between W/m² and BTU/(h·ft²) constantly.
