What does joule per hour measure?

Joule per hour quantifies power as the energy transferred or converted in one hour.

How is calorie (th)/second defined?

Calorie (th)/second measures power by the rate of thermochemical calories transferred per second, where 1 cal(th) equals exactly 4.184 joules.

Why convert from J/h to cal(th)/s?

This conversion translates long-duration low-rate energy measurements into thermal power units useful in calorimetry and engineering.

Examples

Convert 10 J/h: 10 × 0.0000663905 = 0.000663905 cal(th)/s
Convert 1000 J/h: 1000 × 0.0000663905 = 0.0663905 cal(th)/s

Common Use Cases

Expressing very low continuous power or standby losses of small electronics over hours
Translating long-duration energy measurements into instantaneous power rates for engineering
Analyzing slow thermal losses or heat output in laboratory experiments
Reporting heat flow in calorimetry using calorie (th)/second units
Converting legacy thermal power data for HVAC and process calculations

Tips & Best Practices

Ensure correct unit selection when entering values
Use the tool for low-rate power conversions over longer time intervals
Handle converted values carefully due to the small numerical scale
Understand that joule/hour is less suited for instantaneous power measurements
Verify definitions of calories when comparing with other calorie-based units

Limitations

Joule/hour measures energy transfer over long durations, limiting instantaneous accuracy
Calorie (th)/second is based on a fixed thermochemical calorie which differs from other calorie definitions
Conversion results involve very small numbers requiring attention to decimal precision
