About these units
The watt per square centimeter (W/cm²) is a metric unit of heat flux density, equal to 10,000 watts per square meter.
The watt per square inch (W/in²) is an imperial unit of heat flux density, equal to 1,550.0031 watts per square meter.
Going the other way, 1 watt per square inch = 0.15500031 watts per square centimeter. 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.
