Convert joule/second/square metre/k to watt/square metre/k
Joule/Second/Square Metre/K
The joule per second per square metre per kelvin (J/(s·m²·K)) is dimensionally identical to W/(m²·K). It makes explicit the energy-rate interpretation of the heat transfer coefficient. Used interchangeably with W/(m²·K) in educational materials and engineering references that prefer explicit unit decomposition.
Watt/Square Metre/K
The watt per square metre per kelvin (W/(m²·K)) is the SI unit of heat transfer coefficient, also known as the U-value or film coefficient. It quantifies the rate of heat transfer per unit area per unit temperature difference. Typical values range from 2–25 W/(m²·K) for free convection to over 10,000 W/(m²·K) for boiling.
