Frequently Asked Questions
-
What does Btu (th)/hour/square foot measure?
-
It measures heat flux density as the rate of heat transfer per hour through one square foot of area, commonly in building science and HVAC.
-
When is dyne/hour/centimeter used?
-
Dyne/hour/centimeter is used for small heat flux measurements in older CGS-based laboratory studies, astrophysics, meteorology, and microscale research.
-
Why convert between these two units?
-
Conversion is necessary to interpret or compare heat flux data across different unit systems, especially when integrating building science results with CGS-based scientific literature.
Key Terminology
-
Btu (th)/hour/square foot
-
A unit of heat flux density representing one thermochemical British thermal unit of heat transferred per hour through one square foot of surface area.
-
dyne/hour/centimeter
-
A CGS-derived unit of heat flux density indicating one dyne of force per hour per centimeter length, dimensionally equivalent to erg per second per square centimeter.
-
Heat flux density
-
A measure of heat transfer rate per unit area, important in thermal sciences and engineering.
