Key Terminology
-
Joule/second/square meter
-
A unit measuring heat flow rate per unit area; equivalent to watt per square meter.
-
Calorie (IT)/hour/square centimeter
-
A heat flux density unit representing heat transfer rate over one square centimeter per hour using International Table calories.
-
Heat Flux Density
-
Thermal power crossing or incident on a surface per unit area, expressed in units such as W·m⁻² or cal(IT)/h/cm².
