The Uses of Petawatts to Watts Conversion
A petawatt is an enormously large unit used for peak, instantaneous bursts of power, so this conversion mostly comes up when comparing such a figure against familiar continuous-power quantities.
Describing Peak Power of Ultra-High-Intensity Lasers
Laser physicists who measure a facility's continuous power draw in watts convert the peak instantaneous output of an ultra-short pulse laser into petawatts to describe its extreme burst intensity.
Comparing Pulsed Fusion Experiment Output
Researchers at inertial confinement fusion facilities who track steady-state power in watts convert a pulse's peak output into petawatts to compare against other record-setting experiments.
Framing Lightning Strike Peak Power Estimates
Atmospheric scientists estimating a powerful lightning strike's peak instantaneous power, first calculated in watts from current and voltage data, convert the figure into petawatts for comparison with laser research benchmarks.

Frequently Asked Questions
How many watts are in 1 petawatt?
1 petawatt equals 1e+15 watts, a figure useful for anyone working at the peak laser pulse and extreme short-burst power research scale.
How many petawatts are in 1 watt?
1 watt equals approximately 1e-15 petawatts, which puts the size of a single watt into perspective against the petawatt.
Why would anyone convert petawatts to watts?
This conversion is mostly used in laser physics or fusion research, such as describing the peak instantaneous power of an ultra-short pulse laser compared against everyday or continuous power figures.
Just how big is a petawatt compared to a watt?
A petawatt is enormously larger: it takes a quadrillion (1,000,000,000,000,000) watts to equal just one petawatt.
