What does one watt-second represent in energy terms?

One watt-second (W·s) is equal to the energy transferred by one watt of power in one second, and it is dimensionally the same as one joule.

Why convert watt-seconds to Btu (IT)?

Converting watt-seconds to Btu (IT) helps relate electrical or mechanical energy amounts to thermal energy units used in heating, cooling, and thermodynamic calculations.

Is Btu (IT) suitable for measuring short electrical impulses?

Since Btu (IT) is mainly a thermal energy unit, applying it to very short electrical impulses may need careful interpretation due to different contexts and measurement scopes.
