What does 1 Btu (IT)/hour represent?

It is the power corresponding to one International Table British thermal unit of heat transferred per hour, commonly used in heat transfer and HVAC measurements.

Why convert Btu (IT)/hour to joule/second?

Converting to joule/second translates heat transfer rates into the SI unit of power, ensuring consistency in scientific calculations and engineering specifications.

Is joule/second the same as watts?

Yes, one joule per second equals one watt, which is the SI derived unit of power.
