What Is This Tool?
This unit converter enables conversion between pound-foot per hour, a legacy imperial power measurement, and ton (refrigeration), a unit expressing cooling capacity. It serves engineers and users working with both mechanical power and HVAC refrigeration ratings.
How to Use This Tool?
-
Enter the power value in pound-foot/hour units.
-
Select pound-foot/hour as the input unit.
-
Choose ton (refrigeration) as the output unit.
-
Press convert to obtain the corresponding cooling capacity value.
Key Features
-
Converts pound-foot/hour to ton (refrigeration) units.
-
Handles very low mechanical power values used in legacy and historical contexts.
-
Supports HVAC and refrigeration industry conversions for cooling capacity evaluation.
-
Browser-based and easy to use without installation.
Examples
-
10,000 pound-foot/hour equals approximately 0.00107088955 ton (refrigeration).
-
50,000 pound-foot/hour converts to about 0.00535444776 ton (refrigeration).
Common Use Cases
-
Translating mechanical power from legacy imperial units into refrigeration cooling capacity.
-
Evaluating HVAC system load calculations and sizing equipment.
-
Documenting and restoring historical or vintage mechanical equipment specifications.
Tips & Best Practices
-
Use the tool to compare very low mechanical work rates within the HVAC context.
-
Apply conversions primarily for integrative or comparative analysis, not exact energy equivalence.
-
Verify inputs carefully due to the very small conversion factor to avoid misinterpretation.
Limitations
-
The scale difference results in very small output values from conversion.
-
Ton (refrigeration) measures heat removal rather than mechanical power.
-
Conversions are best for comparison, not direct equivalence of energy types.
-
Rounding and precision issues can occur due to the minute conversion factor.
Frequently Asked Questions
-
What does pound-foot/hour measure?
-
Pound-foot/hour is an imperial unit measuring mechanical power as the rate of foot-pound force work done per hour, typically representing very low continuous mechanical output.
-
What is ton (refrigeration) used for?
-
Ton (refrigeration) expresses cooling capacity, defined by the heat removal rate needed to melt one short ton of ice in 24 hours, commonly used in HVAC and refrigeration equipment ratings.
-
Is the conversion direct or approximate?
-
The conversion between pound-foot/hour and ton (refrigeration) uses a precise factor but applies to different energy types, so it is most useful for comparison rather than direct equivalence.
Key Terminology
-
Pound-foot/hour [lbf*ft/h]
-
An imperial power unit representing the rate of work done equal to one foot-pound force per hour, often used for very low mechanical output and historical measurements.
-
Ton (refrigeration)
-
A non-SI power unit defining cooling capacity based on the heat required to melt one short ton of ice over 24 hours, commonly applied in HVAC system ratings.
-
Conversion factor
-
A numerical value used to translate a quantity from one unit to another, here approximately 1.0708895528789e-7 ton (refrigeration) per pound-foot/hour.
