What does a kilocalorie (IT)/second measure?

It measures power as one kilocalorie (International Table) of energy transferred every second, equivalent to 4,186.8 watts.

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

This helps translate older thermal power measurements into the very small power scales used in nanoscale, quantum, or low-power electronic systems.

Can this conversion be used for precise experimental measurements?

The conversion serves mainly to bridge scales; precision depends greatly on context and measurement sensitivity.
