What Is This Tool?
This unit converter transforms power measurements from thermochemical British thermal units per hour (Btu (th)/hour) into nanojoules per second (nJ/s), enabling the translation of moderate to large-scale thermal power quantities into very small, precise power units. The tool is useful for bridging between heating/cooling systems and ultra-low power electronic or photonic devices.

Precision differences between large-scale heat and nanowatt power units may affect practical accuracy
Frequently Asked Questions
-
What does 1 Btu (th)/hour represent?
-
It is a unit of power indicating one thermochemical British thermal unit of heat transferred per hour, used to quantify heating or cooling rates.
-
Why is nanojoule/second used for power measurements?
-
Nanojoule/second measures very small power levels, ideal for ultra-low-power electronics, energy harvesting, and precise photonic applications.
-
Can I convert from nanojoule/second back to Btu (th)/hour?
-
