What does erg/second measure?

Erg/second is a CGS unit of power representing the energy transferred at a rate of one erg per second.

What is kilojoule/hour used for?

Kilojoule/hour measures the rate of energy transfer, commonly used for small-to-moderate power rates over hourly intervals.

Why convert erg/second to kilojoule/hour?

Converting allows interpreting CGS-based power measurements in units that describe energy rates over an hour, useful in fields like building physics and metabolic studies.
