Real-World Examples
The Uses of Exawatts to Watts Conversion
An exawatt is an almost unimaginably large unit, so this conversion mostly comes up when comparing a planetary-scale power figure against familiar engineering quantities.
Comparing Global Energy Consumption to Stellar Output
Scientists estimating humanity's total instantaneous global power consumption, first tallied in watts from national grid data, convert the grand total into exawatts to compare it against solar or stellar output figures.
Framing Total Solar Power Reaching Earth
Climate researchers calculating the total solar power striking the Earth's surface at any instant, first worked out in watts from irradiance data, convert the figure into exawatts for a planetary-scale comparison.
Contextualizing Theoretical Fusion Reactor Output
Physicists discussing a theoretical large-scale fusion reactor network's combined output, first modeled in watts per reactor, convert the aggregate total into exawatts for scientific papers.

Frequently Asked Questions
How many watts are in 1 exawatt?
1 exawatt equals 1e+18 watts, a figure useful for anyone working at the planetary and astrophysical energy-output scale scale.
How many exawatts are in 1 watt?
1 watt equals approximately 1e-18 exawatts, which puts the size of a single watt into perspective against the exawatt.
Why would anyone convert exawatts to watts?
This conversion is mostly used in astrophysics or planetary energy science, such as comparing total solar output or global energy consumption against grid-scale power figures.
Just how big is an exawatt compared to a watt?
An exawatt is almost unimaginably larger: it takes a quintillion (1,000,000,000,000,000,000) watts to equal just one exawatt.
