What does one calorie (IT)/second represent?

It is a unit of power indicating the rate of energy transfer of one International Table calorie each second, typically used to describe thermal power or heat transfer rates.

When should I use joule/hour instead of joule/second (watt)?

Joule/hour is preferable for expressing very low continuous power or heat transfer measured over longer periods, while joule/second is better suited for instantaneous or higher power rates.

Why might conversions involving calorie (IT)/second be approximate?

Because the International Table calorie is an older unit replaced by the joule, historical definitions and variations can cause the conversions to be approximate rather than exact.

Examples

Convert 2 cal/s: 2 × 15072.48 = 30144.96 J/h
Convert 0.5 cal/s: 0.5 × 15072.48 = 7536.24 J/h

Common Use Cases

Expressing heat-transfer rates in calorimetry using the International Table calorie
Analyzing heating or cooling capacity described in older technical literature
Converting historical thermal power units to current SI-based values
Estimating low continuous power losses in electronic devices over extended periods
Studying slow heat output or thermal losses in laboratory experiments with hourly measurement intervals

Tips & Best Practices

Ensure correct selection of input and output units before converting
Use this unit for low power or slow heat transfer rate contexts
Remember that joule/hour reflects energy transfer over an hour, not instantaneous power
Refer to modern SI units for higher power measurements if needed
Validate conversions when working with historical or approximate data

Limitations

The International Table calorie is outdated and conversions may not be exact
Joule/hour is intended for low power values, making it less practical for high-power conversions
Time scaling differences require attention when interpreting results for instantaneous power
Care needed converting historical data due to variations in energy unit definitions

Key Terminology

Calorie (IT)/second [cal/s]: A power unit measuring the rate of energy transfer of one International Table calorie per second, used to quantify thermal power based on the historical calorie unit.
Joule/hour [J/h]: A power unit representing one joule of energy transferred each hour, often used to express very low power rates or slow energy transfer over time.
Thermal power: The rate at which heat energy is transferred or converted, often measured in units like calorie/second or joule/hour.
