Frequently Asked Questions
-
What does Btu (IT)/square foot measure?
-
It measures the amount of thermal energy per unit area, specifically the energy in British thermal units according to the International Table definition distributed over one square foot.
-
What is a Langley unit used for?
-
The Langley is used to express the incident heat energy per unit area, commonly used for measuring solar radiation received by surfaces.
-
Can this converter handle heat flux rates?
-
No, this converter only deals with static heat energy per area and does not provide conversions involving heat flux, which includes a time factor.
Key Terminology
-
Btu (IT)/square foot
-
A measure of thermal energy per area based on British thermal units using the International Table, quantifying energy contained in or delivered to one square foot of surface.
-
Langley
-
A unit of incident heat energy per area equal to one calorie per square centimeter, used to quantify solar radiation or heat energy received by a surface.
-
Heat Density
-
The amount of heat energy contained or delivered per unit area, distinct from heat flux which includes a time component.
