What is the exact conversion rate from kilocalorie (IT) to watt-second?

One kilocalorie (IT) equals 4186.8 watt-seconds.

Why is watt-second used instead of joule in some cases?

Watt-second highlights energy delivered over time at constant power and is often convenient in power-time and electrical applications, though it is dimensionally identical to the joule.

Are there any differences between kilocalorie (IT) and other calorie units?

Yes, the kilocalorie (IT) specifically uses the international-table calorie which differs from other calorie definitions, so consistency is important.
