What Is This Tool?
This converter allows you to change power measurements from foot pound-force per second, an imperial mechanical power unit, into calorie (thermochemical) per hour, a thermal power unit used in heat transfer and calorimetry contexts.
How to Use This Tool?
-
Enter the value in foot pound-force per second you wish to convert
-
Select the target unit as calorie (th)/hour
-
Click convert to see the equivalent thermal power
-
Use the result for analysis in mechanical or thermal contexts
Key Features
-
Converts mechanical power in ft·lbf/s to thermal power in cal(th)/h
-
Uses precise conversion based on standard definitions
-
Supports applications in engineering, calorimetry, and physiology
-
Includes easy input and output for practical use
Examples
-
Convert 2 ft·lbf/s to calorie (th)/hour: 2 × 1166.5737605129 = 2333.15 cal(th)/h
-
Convert 0.5 ft·lbf/s to calorie (th)/hour: 0.5 × 1166.5737605129 = 583.29 cal(th)/h
Common Use Cases
-
Translating mechanical power in imperial units to thermal power for heat transfer studies
-
Analyzing small heat outputs in laboratory calorimetry experiments
-
Evaluating metabolic heat production in physiological research
-
Assessing thermal management of small devices using non-SI units
Tips & Best Practices
-
Ensure consistent units when comparing mechanical and thermal power
-
Use this conversion primarily when linking mechanical work to heat energy
-
Remember that calorie (th)/hour is less common than watts for power measurements
-
Consider physical context when interpreting converted values due to unit differences
Limitations
-
Foot pound-force per second measures mechanical power while calorie (th)/hour measures thermal power, representing different contexts
-
Calorie (th)/hour is a non-SI unit and conversions to it might introduce rounding variations
-
Conversion assumes steady power without accounting for transient or non-mechanical heat sources
Frequently Asked Questions
-
What does foot pound-force per second measure?
-
It measures mechanical power as the work done when a pound-force moves one foot every second.
-
Where is calorie (th)/hour commonly used?
-
It is used to measure thermal power in applications like laboratory calorimetry and physiological heat production.
-
Can I directly compare ft·lbf/s and cal(th)/h values?
-
Since they measure different types of power, direct comparison requires careful consideration of the physical context.
Key Terminology
-
Foot pound-force per second (ft·lbf/s)
-
An imperial unit of mechanical power equal to one pound-force moving one foot per second.
-
Calorie (thermochemical) per hour [cal (th)/h]
-
A unit measuring thermal power as one thermochemical calorie delivered each hour.
-
Power
-
The rate at which work is done or energy is transferred.
