The watt per square meter is the SI derived unit of heat flux, expressing the rate of heat transfer through a unit surface area.
Derived from the base SI units of heat transfer engineering, it became standard for surface heat loss and solar radiation calculations.
Measurement system: International System of Units (SI). SI equivalent: Base SI heat flux unit.
