What does kilojoule per second measure?

Kilojoule per second (kJ/s) measures power as the rate of energy transfer, equal to 1,000 joules per second and equivalent to one kilowatt.

When is calorie (th)/hour used?

Calorie (th)/hour is used to quantify small thermal power rates, often in laboratory calorimetry, metabolic studies, and for small devices requiring non-SI thermal units.

What is the conversion factor between kJ/s and cal (th)/h?

1 kilojoule per second equals 860,420.6500956 thermochemical calories per hour.

What Is This Tool?

This online converter allows you to translate power values from kilojoule per second (kJ/s), a common unit of electrical and mechanical power, into thermochemical calories per hour (cal (th)/h), used for detailed thermal power measurements in scientific and engineering contexts.

How to Use This Tool?

Enter the power value in kilojoule per second (kJ/s) into the input field
Select kilojoule/second as the source unit and calorie (th)/hour as the target unit
Click the convert button to see the equivalent power in thermochemical calories per hour
Use the results to interpret or report thermal power values in your application

Key Features

Converts power units from kilojoule/second to calorie (th)/hour accurately
Supports applications in electrical, mechanical, and thermal power measurements
Provides clear definitions for both units and their typical usage scenarios
Includes real-life examples to illustrate the conversion outcome

Examples

2 kJ/s equals approximately 1,720,841.3 cal (th)/h
0.5 kJ/s converts to roughly 430,210.3 cal (th)/h

Common Use Cases

Evaluating power output or consumption in appliances, motors, and generators
Measuring thermal energy transfer rates in HVAC and boiler systems
Reporting small heat-transfer rates in laboratory calorimetry for chemical reactions
Expressing metabolic heat production in physiological studies
Specifying low heating or heat loss rates for small devices using non-SI thermal units

Tips & Best Practices

Always confirm unit definitions before converting to ensure consistency
Use this converter when precise thermal power measurement with calories per hour is required
Interpret results with care when comparing with SI power units like watts
Keep in mind the calorie (th)/hour unit is better suited for small-scale thermal power

Limitations

Calorie (th)/hour is a non-SI unit with limited precision for large scale values
Conversions assume a static definition of the thermochemical calorie standard
Results may vary if different calorie definitions are applied
Less common for general power measurement outside specialized thermal contexts
