What is an attojoule per second?

An attojoule per second is a unit of power equal to 10^-18 joules per second, used to measure very small rates of energy transfer.

Why convert attojoule/second to calorie (IT)/second?

Converting allows expressing extremely small power values in heat transfer terms using the historical International Table calorie unit, linking nanoscale measurements with traditional thermal units.

Is calorie (IT)/second still widely used?

Calorie (IT)/second is mainly historical and less common in modern applications, but remains relevant in certain laboratory and engineering fields involving legacy data.
