What does attojoule/second represent?

Attojoule per second is a power unit representing 10^-18 joules transferred every second, used to quantify extremely small rates of energy transfer.

Why use calorie (IT)/hour for power measurements?

Calorie (IT) per hour measures steady, small heat flow rates and is common in thermal and calorimetric contexts, especially when interpreting historical or legacy data.

Are there challenges converting between these units?

Yes, due to the small magnitude of attojoule/second and the larger calorie/hour unit, precision issues can arise, requiring careful measurement and interpretation.
