Frequently Asked Questions
-
What does the unit joule/second/square meter/K represent?
-
It is a heat transfer coefficient measuring the rate of heat flow per unit area per degree of temperature difference, commonly used in SI units.
-
Why convert to calorie (IT)/second/square centimeter/°C units?
-
Because some older technical literature and experimental results report heat transfer coefficients in calorie-based units, making conversion necessary for analysis.
-
Are joule/second/square meter/K and calorie (IT)/second/square centimeter/°C directly comparable?
-
They measure the same physical quantity but differ in unit bases for energy, area, and temperature, requiring conversion for accurate comparison.
