What is a watt-second (W·s)?

A watt-second is a unit of energy representing the work done or heat transferred when one watt of power is applied for one second, identical in dimension to a joule.

Why convert watt-seconds to kilocalories (th)?

Conversion helps interpret energy from electrical or mechanical sources in terms of nutritional energy or heat content used in thermal engineering and metabolic studies.

Are watt-second and kilocalorie (th) directly comparable?

They measure energy but on vastly different scales, so conversion results in very small values when going from watt-seconds to kilocalories (th).
