What does a pound-foot per minute measure?

It measures mechanical power as the rate of doing work when a force of one pound-force moves through one foot in one minute.

Why convert pound-foot/minute to calorie (th)/hour?

To translate mechanical power in imperial units into thermal power units suited for heat transfer and calorimetry analysis.

Is the watt a better unit than calorie (th)/hour?

Yes, the watt is the preferred SI unit for power and is more commonly used across many applications.

What Is This Tool?

This converter allows users to translate power measurements from pound-foot per minute (lbf·ft/min), a unit commonly used in mechanical engineering, to calorie (th)/hour [cal (th)/h], which quantifies thermal power in calorimetry and heat transfer.

How to Use This Tool?

Enter the power value in pound-foot per minute you want to convert.
Select 'pound-foot/minute' as the input unit if not preselected.
Choose 'calorie (th)/hour [cal (th)/h]' as the output unit.
Click the convert button to see the equivalent thermal power value.
Use the result for analysis in heat transfer or physiological heat production contexts.

Key Features

Converts power from a mechanical unit (pound-foot/minute) to a thermal power unit (calorie (th)/hour).
Supports calculations relevant for small shaft power, heat transfer, and metabolic heat rates.
Provides exact conversion factors based on established mechanical and thermal unit definitions.
Suitable for legacy engineering data, laboratory calorimetry, and thermal management scenarios.
Browser-based and easy to use without additional software installation.

Examples

5 pound-foot/minute converts to 97.21448 calorie (th)/hour [cal (th)/h].
0.1 pound-foot/minute converts to 1.94429 calorie (th)/hour [cal (th)/h].

Common Use Cases

Expressing small shaft or rotary power in imperial engineering settings.
Converting torque and speed data from hand tools and low-power motors to power values.
Reporting small heat-transfer rates during laboratory calorimetry.
Expressing metabolic heat production rates using calories per hour.
Comparing mechanical power ratings using horsepower and thermal power equivalents.

Tips & Best Practices

Verify the units selected before conversion to avoid errors.
Use this converter when dealing with small power values common in mechanical or thermal measurements.
Remember that these units represent different physical domains; consider energy transfer efficiency in interpretations.
For higher power ranges, convert to standard SI units like watts or kilowatts for better relevance.
Use the watt as a reference unit when accuracy and standardization are needed.

Limitations

Conversion assumes perfect energy transfer between mechanical and thermal power, which may not be realistic.
Units cover very small power values; conversion to larger SI units might be needed for bigger scales.
Thermochemical calorie units are less common and specialized compared to the standard watts.
Direct comparisons can be misleading due to differences in physical nature of mechanical and thermal power.
