Frequently Asked Questions
-
What does CHU/hour/square foot measure?
-
It measures the rate of heat transfer per unit area, expressed as CHUs of thermal energy delivered or removed per hour across one square foot.
-
Why convert to Calorie (IT)/minute/square centimeter?
-
Because it allows analysis of heat flux density on a smaller surface area and shorter time scale, which is useful in precise thermal testing and specific applications.
-
Can I use this conversion for other heat flux units?
-
This tool specifically converts between CHU/hour/square foot and Calorie (IT)/minute/square centimeter and is not intended for other heat flux unit conversions.
