What Is This Tool?
This converter lets you translate power values from the unit calorie (IT)/hour, representing heat transfer rates based on the International Table calorie, into calorie (th)/minute, which is based on the thermochemical calorie. It supports accurate data comparison in various scientific and technical contexts.
How to Use This Tool?
-
Enter the numerical value in calorie (IT)/hour you want to convert.
-
Select the starting unit as calorie (IT)/hour and the target unit as calorie (th)/minute.
-
Click convert to obtain the equivalent power value in calorie (th)/minute.
-
Use the result to support your calorimetry or metabolic rate analysis.
Key Features
-
Converts power values from calorie (IT)/hour to calorie (th)/minute.
-
Based on exact conversion factors between International Table and thermochemical calories.
-
Supports precise energy transfer comparisons in thermal and calorimetric applications.
-
Useful for interpreting historical technical data and laboratory measurements.
Examples
-
10 cal (IT)/hour equals 0.166778203 cal (th)/minute.
-
50 cal (IT)/hour equals 0.833891015 cal (th)/minute.
Common Use Cases
-
Reporting small heat-transfer rates in laboratory calorimetry or thermal tests.
-
Converting historical data or literature using calorie-based units instead of SI.
-
Estimating minor heat losses or gains in experimentally insulated components.
-
Expressing metabolic rates for humans or animals in physiological studies.
-
Characterizing low-rate heating in food science and cooking energy trials.
Tips & Best Practices
-
Carefully consider the difference in calorie definitions when interpreting data.
-
Remember the time unit difference: conversion is from per hour to per minute.
-
Apply this conversion primarily for small-scale heat flow or power values.
-
Use the tool to maintain consistent unit usage in scientific reporting.
-
Validate results against experimental conditions for accuracy.
Limitations
-
Differences between International Table and thermochemical calorie definitions must be acknowledged.
-
Conversion involves different time bases (hour vs. minute), which can cause confusion.
-
Primarily intended for very small power or heat transfer values.
-
May not be appropriate for large-scale industrial energy transfer applications.
Frequently Asked Questions
-
What does calorie (IT)/hour measure?
-
It measures power as a rate of energy transfer equal to one International Table calorie per hour, used for small steady heat flows.
-
Why convert from calorie (IT)/hour to calorie (th)/minute?
-
To translate heat-flow rates between two calorie definitions and time bases, useful for consistent data comparison in calorimetry and metabolic studies.
-
Is this conversion suitable for large heat transfer values?
-
No, it is mainly designed for small-scale power values relevant in laboratory or experimental setups.
Key Terminology
-
Calorie (IT)/hour
-
