Limitations
-
Foot pound-force/hour is a very small, non-SI mechanical power unit with limited practical use
-
Btu (th)/hour pertains only to thermal power, so consider system-specific factors before applying conversions
-
Conversion does not equalize thermal and mechanical energy without thermodynamic considerations
Frequently Asked Questions
-
What does foot pound-force/hour measure?
-
It measures mechanical power as one foot-pound-force of work done every hour, commonly used in legacy imperial systems.
-
Why convert foot pound-force/hour to Btu (th)/hour?
-
To express mechanical power in terms of thermal energy transfer, useful for HVAC and heating/cooling equipment specifications.
-
Can I use the conversion for any power comparison?
-
No, since foot pound-force/hour and Btu (th)/hour represent different types of power, consider the context and system efficiencies.
Key Terminology
-
Foot pound-force/hour
-
A non-SI mechanical power unit representing one foot-pound-force of work per hour, used in legacy imperial systems.
-
Btu (th)/hour
-
A thermal power unit equal to one thermochemical British thermal unit of heat transferred per hour, used to quantify heat transfer rates.
