What Is This Tool?
This converter enables you to transform power values from calorie (th)/hour, a unit measuring thermal power derived from thermochemical calories, into watts, the internationally recognized SI unit for power. It is ideal for applications in laboratory calorimetry, physiological studies, and small device power measurements.
How to Use This Tool?

Browser-based and easy to use without installation.
Examples
-
Convert 10 calorie (th)/hour to watts: 10 × 0.0011622222 W = 0.011622222 W.
-
Convert 500 calorie (th)/hour to watts: 500 × 0.0011622222 W = 0.5811111 W.
Common Use Cases
-
Reporting small heat-transfer rates in laboratory calorimetry.
-
Expressing metabolic or physiological heat-production rates.
-
Specifying low heating or heat-loss rates for small devices or components.
-
Analyzing thermal power in electrical, mechanical, and renewable energy contexts.
Tips & Best Practices
-
Use the tool for low power measurements where calorie (th)/hour units are common.
-
Convert to watts for standardization and easier communication in scientific and engineering fields.
-
Double-check unit selections to ensure accurate conversion results.
-
Utilize the tool for comparing thermal power outputs in various experimental setups.
Limitations
-
The calorie (th)/hour unit corresponds to a very small power magnitude (~1.16 milliwatts).
-
Not ideal for converting large-scale power values where watts or kilowatts are the norm.
-
Rounding inaccuracies may occur when dealing with extremely small or very large inputs.
-
Best applied for precise low-level thermal power measurements rather than high power scenarios.
Frequently Asked Questions
-
What does calorie (th)/hour measure?
-
Calorie (th)/hour measures the rate of thermal energy transfer based on the thermochemical calorie, representing small-scale heat power.
-
Why convert calorie (th)/hour to watts?
-
Converting to watts standardizes the power measurement using the SI unit, facilitating easier interpretation, comparison, and usage in scientific and engineering contexts.
-
Can this tool convert large power values?
-
This converter is best suited for low power values typical in thermal and physiological measurements; large power values are usually expressed directly in watts or kilowatts.
Key Terminology
