Not suitable for energy or heat measurements that are not rate-based per unit area
Frequently Asked Questions
-
What does Btu (IT)/minute/square foot measure?
-
It measures the rate of heat transfer per minute across one square foot of area using the International Table British thermal unit as energy.
-
Why convert Btu (IT)/minute/square foot to foot pound/minute/square foot?
-
This conversion allows consistent comparison and reporting of heat flux density between systems using British thermal units and those using imperial foot-pound energy units.
-
Can this converter be used for non-heat flux density units?
-
No, this tool is specifically designed for converting heat flux density units measured as energy transfer rate per unit area and time.
Key Terminology
