What does 1 petawatt represent?

One petawatt (PW) is an SI unit of power equal to 10^15 watts, measuring the rate of energy transfer or conversion per unit time.

How is joule per hour related to watt?

One joule per hour (J/h) equals one joule transferred in one hour, which corresponds to approximately 1/3600 watts.

Why convert petawatt to joule/hour?

Converting petawatt to joule/hour helps translate extremely high instantaneous power into an equivalent hourly energy transfer for better analysis and comparison.
