Frequently Asked Questions

Why are watt per square meter per kelvin and kilocalorie (IT) per hour per square meter per degree Celsius used interchangeably for heat transfer?
Though the units use different temperature scales, the size of 1 kelvin and 1 degree Celsius is the same for temperature differences, allowing their interchangeability in heat transfer coefficient calculations.

Key Terminology

Watt per square meter per kelvin (W·m⁻²·K⁻¹)
SI unit measuring the heat transfer coefficient indicating heat flux per unit area and temperature difference in kelvin.
Kilocalorie (IT)/hour/square meter/°C
A unit of heat transfer coefficient expressing steady heat flow per unit area and per degree Celsius temperature difference, used in regional and legacy engineering contexts.
Heat transfer coefficient
A measure of heat transfer rate per unit area and temperature difference between a surface and its surroundings.
