What Is This Tool?
This converter transforms power values from picojoule per second (pJ/s), a unit for extremely small power levels commonly used in nanoelectronics and photonics, into calorie (IT) per second (cal/s), a unit expressing thermal power based on International Table calories. It facilitates conversion between these distinct units to support scientific and engineering tasks involving heat transfer and ultra-low power measurement.
How to Use This Tool?

Reporting optical power in sensitive photonics instruments.
-
Expressing energy efficiency rates in low-energy digital electronics as power.
-
Determining heat-transfer rates in laboratory calorimetry using calorie units.
-
Analyzing older engineering data where thermal power was expressed in calories.
-
Converting nano-scale power measurements into thermal power units for comparison.
Tips & Best Practices
-
Always verify the units to ensure correct input and output selections.
-
Use this tool primarily for interpreting very small power values in specialized contexts.
-
Understand the difference in magnitude and application between picojoule-based and calorie-based units.
-
Consider aggregating values when dealing with extremely low power to improve practical relevance.
-
Use results for comparative and conversion purposes rather than precise thermal energy quantification.
Limitations
-
The conversion factor is extremely small due to the large magnitude difference between units.
-
Picojoule power values may be too minor for direct thermal energy interpretations without further processing.
-
Unit context differences require careful analysis to avoid misinterpretation in scientific or engineering uses.
Frequently Asked Questions
-
What does 1 picojoule per second represent?
-
One picojoule per second defines a power level equal to 10⁻¹² watts, commonly used to quantify ultra-small continuous power in fields like microelectronics and photonics.
-
Why convert picojoule/second to calorie (IT)/second?
-
This conversion translates very small power measurements into thermal energy units for heat transfer analysis or to interpret historical engineering data expressed in calorie units.
