What is kilowatt per square meter used for?

It measures the rate of heat energy transfer per unit area and is commonly used in solar irradiance, fire safety testing, and thermal engineering analyses.

Why convert kilowatt/square meter to foot pound/minute/square foot?

Converting between these units helps interpret heat flux density values in imperial units often found in legacy U.S. engineering, HVAC documents, and thermal measurement reports.

Are imperial units preferred for heat flux measurements?

Imperial units are mainly used in legacy or regional contexts; SI units like kW/m² are generally preferred for scientific and global applications.
