Conversion accuracy depends on precise definitions of thermal units used
Frequently Asked Questions
-
What does Btu (IT)/minute/square foot measure?
-
It measures heat flux density, representing the rate of heat transfer per unit area in British thermal units per minute over one square foot.
-
When should I use calorie (th)/hour/square centimeter units?
-
This unit is useful for small surface heat-flux measurements, laboratory calorimetry, or historical solar irradiance data typically in scientific or thermal testing contexts.
-
How is the conversion factor applied?
-
Multiply the value in Btu (IT)/minute/square foot by approximately 16.2857 to convert it to calorie (th)/hour/square centimeter.
Key Terminology
-
Btu (IT)/minute/square foot
-
A heat flux density unit quantifying energy transfer in British thermal units per minute over one square foot, commonly used in HVAC and building thermal analysis.
-
Calorie (th)/hour/square centimeter
-
