What Is This Tool?
This converter transforms power values measured in pound-foot per hour, an imperial unit for low mechanical work rates, into calorie (IT) per second, a unit used to quantify thermal power based on the International Table calorie. It enables conversions bridging mechanical work and heat-transfer rates.

Common Use Cases
-
Documenting low mechanical power output in vintage machinery
-
Expressing heat transfer rates in calorimetry using International Table calories
-
Converting historical imperial mechanical power ratings to thermal power units
-
Analyzing heating or cooling capacities in older thermal systems
-
Translating legacy power measures for engineering assessments
Tips & Best Practices
-
Ensure numerical precision due to small unit values
-
Use conversions primarily for legacy or specialized equipment
-
Understand that mechanical and thermal power units have different physical bases
-
Confirm the context is appropriate for correlating mechanical work to heat transfer
-
Prefer SI units (watts) for modern engineering when possible
Limitations
-
Conversion values are very small, requiring careful calculation
-
Only meaningful when connecting mechanical work to thermal power concepts
-
Pound-foot/hour suits very low power levels; calorie (IT)/second measures thermal power
-
Modern engineering typically uses SI units, limiting contemporary relevance
-
Direct physical interpretation can be limited due to differing unit natures
Frequently Asked Questions
-
What does pound-foot/hour measure?
-
Pound-foot/hour measures mechanical power as foot-pound force of work done per hour, primarily representing very low rates of mechanical output.
-
Why convert pound-foot/hour to calorie (IT)/second?
-
Converting allows comparison of mechanical work rates expressed in imperial units to thermal power or heat-transfer rates using the International Table calorie.
-
Is this conversion common in modern engineering?
-
No, modern engineering mainly uses SI units like watts; these units and conversions are mostly for legacy or specialized applications.
-
Can I directly compare pound-foot/hour and calorie (IT)/second?
-
Because pound-foot/hour measures mechanical power and calorie (IT)/second measures thermal power, direct comparisons make sense mainly when relating mechanical work to thermal energy transfer.
Key Terminology
-
Pound-foot/hour [lbf*ft/h]
-
An imperial unit of power equal to one foot-pound force of work done per hour, typically representing very low mechanical power output.
-
Calorie (IT)/second [cal/s]
-
A unit of power quantifying energy transfer of one International Table calorie per second, used to express thermal power or heat transfer rates.
-
International Table calorie
-
A historical energy unit used as the basis for measuring heat energy in calorie (IT)/second.
