What is Btu (IT) used for?

Btu (IT) measures energy for heating, cooling, fuel combustion, and thermodynamic calculations based on International Steam Tables definitions.

How is a watt-second defined?

A watt-second is the energy transferred by one watt sustained for one second, equivalent in dimension to a joule.

Can I use this conversion in electrical engineering?

Yes, watt-second units are convenient for describing impulse energy and power-time products in electrical systems.
