What does joule/second (J/s) measure?

Joule per second (J/s) is the SI derived unit of power, representing the rate of energy transfer or expenditure equivalent to one watt.

When should I use Btu (IT)/second over joule/second?

Btu (IT)/second is preferred in contexts involving heat transfer, HVAC specifications, and engineering work using British thermal units.

Can this converter be used for non-heat power measurements?

While primarily used for heat and energy transfer contexts, the converter applies wherever power must be expressed in Btu (IT)/second.

How to Convert from Joule/second [J/s] to Btu (IT)/second [Btu/s]

This converter transforms power values measured in joule per second (J/s) into British thermal units per second (Btu (IT)/s) to aid comparisons and calculations in industries utilizing BTU units.
