What does microjoule/second [µJ/s] measure?

Microjoule/second is a unit of power representing the rate of energy transfer of one microjoule every second, often used to quantify very small continuous power levels in electronics and photonics.

Why use calorie (IT)/second instead of watts?

Calorie (IT)/second measures thermal power using the historical International Table calorie and is useful in contexts like calorimetry or older technical literature that use calorie-based units.

Are conversions between µJ/s and cal/s exact?

Conversions use a specific conversion rate but often result in very small decimal numbers, reflecting the difference in magnitude between the units.
