Frequently Asked Questions
-
Why convert calorie (IT)/hour/square centimeter to watt/square meter?
-
Converting to watt per square meter standardizes heat flux density values to an SI unit, facilitating integration with current engineering and scientific applications.
-
Is calorie (IT)/hour/square centimeter commonly used today?
-
No, it is a non-SI unit primarily found in older literature and specific calibration contexts, with watt per square meter being the preferred modern unit.
-
What does the conversion formula represent?
-
The formula precisely relates the rate of heat transferred per unit area from calorie (IT)/hour/square centimeter to watts per square meter based on their definitions.
Key Terminology
-
Calorie (IT)/hour/square centimeter
-
A heat flux density unit indicating the rate of heat transfer in International Table calories per hour over a one square centimeter area; a non-SI unit.
-
Watt per square meter [W/m²]
-
The SI unit measuring heat flux density as the rate of energy transfer (watts) per square meter across or emitted from a surface.
-
Heat Flux Density
-
A measure of heat transfer rate through a surface per unit area, expressed in units such as watt per square meter or calorie per hour per square centimeter.
