What Is This Tool?
This tool enables conversion of power measurements from picojoule per second (pJ/s), a very small unit typically used in microelectronics and photonics, to Btu (IT)/hour, a thermal power unit commonly applied in HVAC and heating systems.
How to Use This Tool?
-
Enter the value in picojoule per second (pJ/s) you want to convert
-
Select the conversion to Btu (IT)/hour [Btu/h]
-
Click the convert button to see the equivalent power in Btu (IT)/hour
-
Review the result to interpret microelectronic or photonic power in thermal units
Key Features
-
Converts extremely small power units (pJ/s) into thermal power units (Btu (IT)/hour)
-
Supports use cases in microelectronics, photonics, and HVAC engineering
-
Provides quick, browser-based power unit conversions
-

-
Handles units used for both low-level electronic power and heat transfer ratings
Examples
-
10 pJ/s equals 3.4121416331279e-11 Btu (IT)/hour
-
1000 pJ/s converts to 3.4121416331279e-9 Btu (IT)/hour
Common Use Cases
-
Determining continuous power consumption of ultra-low-power microcontrollers and sensors
-
Measuring optical power in sensitive photonic detectors or single-photon systems
-
Rating HVAC equipment, including air conditioners and furnaces, using thermal power units
-
Estimating heating output of boilers or gas furnaces
-
Calculating building heat loss and sizing heat exchangers for heating systems
Tips & Best Practices
-
Understand the vastly different magnitudes between picojoule/second and Btu/h units
-
Use this tool primarily to relate tiny continuous electronic power ratings to thermal power scales
-
Be mindful of numerical precision due to very small conversion factors
-
Verify unit selections to ensure appropriate conversion context
-
Apply conversion results in suitable engineering or analytical scenarios considering scale differences
Limitations
-
The scale difference makes picojoule/second values correspond to minuscule fractions of Btu/h
-
Conversions may be impractical for direct thermal system applications
-
Precision challenges exist when working with very small numerical values in conversions
Frequently Asked Questions
-
What does picojoule per second measure?
-
Picojoule per second measures very small power levels, equal to 10⁻¹² watts, often used in microelectronics and photonics.
-
What is Btu (IT)/hour used for?
-
Btu (IT)/hour is used to express heat transfer rates, commonly applied in HVAC equipment ratings and heating system capacity.
-
Why convert from pJ/s to Btu (IT)/hour?
-
Users convert from pJ/s to Btu (IT)/hour to compare tiny continuous electronic power to larger-scale thermal power units in engineering contexts.
Key Terminology
-
Picojoule/second [pJ/s]
-
A unit of power equal to one trillionth of a watt, used for measuring ultra-low power in microelectronics and photonics.
-
Btu (IT)/hour [Btu/h]
-
A unit of power representing one International Table British thermal unit transferred per hour, used in heating and cooling.
