What Is This Tool?
This converter allows you to translate power values from the calorie (IT)/hour unit—used to measure very small heat transfer rates—to pound-foot/hour, a mechanical power unit from the imperial system. It is ideal for thermal engineering, calorimetry, and vintage equipment documentation involving low-level power measurements.

Common Use Cases
-
Reporting small heat-transfer rates during laboratory calorimetry and material thermal testing.
-
Interpreting historical technical data that use calorie or foot-pound power units.
-
Estimating power output in vintage mechanical systems like small clocks or gear trains.
-
Converting legacy mechanical power ratings into SI-equivalent units.
-
Understanding low-level heat losses or mechanical work rates in experimental setups.
Tips & Best Practices
-
Always verify the measurement context—thermal or mechanical—before converting units.
-
Use this tool for very small-scale power rates typical in laboratory or vintage equipment scenarios.
-
Cross-check converted values when documenting historical or technical specifications.
-
Recognize that unit differences mean conversions serve interpretative or documentation purposes.
-
Keep in mind the specific definitions of calorie (IT) and pound-foot units as described.
Limitations
-
Relevant primarily for niche scientific or historical applications dealing with small power values.
-
Not intended for everyday or large-scale power conversion tasks.
-
Thermal and mechanical unit systems differ, so conversions may not represent direct physical equivalence universally.
Frequently Asked Questions
-
What does 1 calorie (IT)/hour represent in power terms?
-
It is a unit for very small power representing energy transfer of one International Table calorie per hour, roughly equal to 1.163×10⁻³ watts.
-
Why convert calorie (IT)/hour to pound-foot/hour?
-
This conversion facilitates translating small thermal power values into mechanical power units used historically in imperial systems for legacy equipment and documentation.
-
Is the conversion suitable for large-scale power measurements?
-
No, this tool is designed for very low power rates typical in laboratory, calorimetric, or vintage mechanical contexts, not for large-scale conversions.
Key Terminology
-
Calorie (IT)/hour [cal/h]
-
A power unit measuring the rate of energy transfer equal to one International Table calorie per hour, used for very small steady heat flow rates.
-
Pound-foot/hour [lbf*ft/h]
-
An imperial power unit representing one foot-pound force of work per hour, used to express very low mechanical power outputs.
-
Conversion Rate
-
The factor used to translate a quantity from calorie (IT)/hour to pound-foot/hour: 1 cal/h = 3.0880252066 lbf*ft/h.
