Heat Transfer Coefficient Units Converter
Coversion factor: 1 W/m2·K = 0.0000238846 cal [IT]/s·cm2·°C
Additional information
The heat transfer coefficient is a fundamental parameter in heat transfer analysis. It represents the rate at which heat is transferred per unit area between two media at different temperatures. The heat transfer coefficient quantifies the ability of a material or fluid to conduct heat and is essential in determining the amount of heat transferred through conduction, convection, or radiation.
The standard unit for heat transfer coefficient in the International System of Units (SI) is Watts per square meter kelvin (W/m2·K).
