What Is This Tool?
This tool enables users to convert power values from Btu (th)/hour, which measures thermal energy transfer rates, into pound-foot per second, an Imperial unit representing mechanical power or work rate. It supports applications across HVAC system design, mechanical engineering, and unit conversions for legacy measurements.

Sizing and rating HVAC equipment like furnaces and air conditioners
-
Specifying heat output for boilers, water heaters, and heat exchangers
-
Estimating building heating and cooling loads or refrigeration capacity
-
Calculating mechanical power from torque and rotational speed in Imperial units
-
Converting legacy technical data from US customary units to modern SI units
Tips & Best Practices
-
Verify the context to ensure the conversion between thermal and mechanical power units is appropriate
-
Use the converter for legacy or specific Imperial unit engineering data
-
Cross-check results when integrating thermal power data with mechanical specifications
-
Be aware that pound-foot/second is less common in modern engineering, so conversions may support specific use cases only
Limitations
-
The units represent different physical quantities, so the conversion assumes matched rate units but may not capture all physical nuances
-
Precision can be affected by rounding and variations in the thermochemical unit definition
-
Pound-foot/second is less commonly used today compared to watts, limiting its relevance to legacy or specialized contexts
Frequently Asked Questions
-
What does one Btu (th)/hour represent?
-
It is a thermal power unit equal to one thermochemical British thermal unit of heat transferred per hour, used to measure heating or cooling rates.
-
Why convert Btu (th)/hour to pound-foot/second?
-
Converting helps translate thermal power rates into mechanical power units commonly used in US customary engineering, aiding cross-disciplinary equipment analysis.
-
Are pound-foot/second units commonly used today?
-
They are less common in modern engineering, mostly found in legacy data or specific Imperial-unit applications.
