What does petawatt measure?

Petawatt is an SI unit of power representing 10^15 watts, which quantifies how quickly energy is transferred or converted per unit time.

Why convert petawatts to kilojoules per hour?

This conversion lets users express ultrahigh power rates as energy transferred over longer periods, making comparisons with smaller or time-aggregated energy measurements easier.

Are kilojoules per hour suitable for measuring petawatt power?

Kilojoule/hour units are typically for small to moderate power rates, so using them to represent petawatt-scale power can be impractical and less clear.
