What Is This Tool?
This tool converts power values from calorie (IT)/second, a unit of thermal power based on the International Table calorie, to foot pound-force per hour, a mechanical power unit used in legacy imperial systems. It helps translate heat-transfer rates expressed in calorie-based units into mechanical power units.

Tips & Best Practices
-
Ensure proper unit selection before conversion to avoid errors
-
Use this tool when working with legacy or historical engineering data
-
Understand that calorie (IT)/second relates to heat energy, foot pound-force/hour to mechanical work
-
Interpret converted results within the context of power type and application
-
Confirm rounding or precision if detailed accuracy is required
Limitations
-
Calorie (IT)/second measures thermal power; foot pound-force/hour measures mechanical work rate
-
Direct equivalence depends on correct energy unit conversions
-
Foot pound-force/hour is a small power unit rarely used in modern SI calculations
-
Precision can be affected by rounding of historical data
-
Applicability is limited to contexts combining heat transfer with mechanical work
Frequently Asked Questions
-
What does calorie (IT)/second measure?
-
Calorie (IT)/second measures the rate of heat energy transfer using the International Table calorie unit, commonly used in thermal power contexts.
-
Why convert calorie (IT)/second to foot pound-force/hour?
-
This conversion helps relate thermal power values in calorie units to mechanical power units used in legacy imperial systems, useful in engineering and historical analysis.
-
Is foot pound-force/hour commonly used today?
