What does calorie (th)/hour measure?

It measures thermal power as the rate of heat transfer equal to one thermochemical calorie delivered per hour.

What is the microjoule/second unit used for?

Microjoule/second quantifies very small continuous power levels such as those in ultra-low-power electronics and photonic systems.

Why convert calorie (th)/hour to microjoule/second?

Converting allows comparison of thermal power measurements with electronic and photonic power in consistent units, especially for micro- and nano-scale applications.

What Is This Tool?

This tool enables users to convert power units from calorie (thermochemical) per hour to microjoule per second. It helps quantify very low rates of thermal energy transfer in units aligned with electronic and photonic power measurements.

How to Use This Tool?

Enter the power value in calorie (th)/hour you wish to convert.
Select calorie (th)/hour as the input unit and microjoule/second as the output unit.
Click convert to obtain the equivalent power expressed in microjoule/second.

Key Features

Converts calorie (th)/hour, a thermal power rate, into microjoule/second, a small-scale electronic power unit.
Useful for integrating thermal power with microelectronics and photonics applications.
Accessible online and easy to use without the need for formulas or manual calculations.

Examples

2 calorie (th)/hour equals approximately 2324.44 microjoule/second.
0.5 calorie (th)/hour equals approximately 581.11 microjoule/second.

Common Use Cases

Measuring small heat-transfer rates in laboratory calorimetry experiments.
Expressing metabolic heat production rates in bioenergetic studies.
Specifying low heating or heat-loss rates of small electronic components.
Evaluating standby power consumption of ultra-low-power microcontrollers and IoT sensors.
Assessing optical power in sensitive photonics and microscopy systems.
Characterizing power output of tiny energy-harvesting devices such as micro solar cells.

Tips & Best Practices

Double-check units before conversion to ensure accurate results.
Use this conversion tool to compare thermal and electronic power measurements consistently.
Be aware that calorie (th)/hour is a non-SI unit and conversions are approximations based on a fixed calorie value.
For larger power values, consider using watt-based units to maintain clarity.

Limitations

Calorie (th)/hour is a non-SI unit and conversion involves approximation.
Microjoule/second is suited for very small power levels; it is not ideal for larger power measurements.
Conversions do not account for variable definitions beyond the fixed thermochemical calorie.
