About Converting Exawatts to Gigawatts
Exawatt and Gigawatt both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Exawatt is 1000000000000000000 watt units, and gigawatt is 1000000000 watt units.
Formula
gigawatts = exawatts × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 exawatt equals 1e+18 base units, and 1 gigawatt equals 1000000000 base units, so dividing one by the other gives the direct exawatt-to-gigawatt factor of 1000000000.
Simple example
1 EW × 1000000000 = 1,000,000,000 GW
1 exawatt = 1,000,000,000 gigawatts.
Real-world example
100 EW × 1000000000 = 100,000,000,000 GW
100 exawatts = 100,000,000,000 gigawatts.

Reverse conversion: Gigawatt to Exawatt
1 GW × 1e-9 = 1e-9 EW
1 gigawatt = 1e-9 exawatts.
exawatts = gigawatts × 1e-9

Frequently asked questions
How many gigawatts are in 1 exawatt?
1 exawatt equals 1,000,000,000 gigawatts, using the exact defined conversion factor rather than an estimate.
How do I convert exawatt to gigawatt?
Multiply the exawatt value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert gigawatt back to exawatt?
Use the reverse factor: 1 gigawatt equals 1e-9 exawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a exawatt?
Exawatt (EW) is a unit of engineering.
What is a gigawatt?
Gigawatt (GW) is a unit of engineering.
Is the exawatt to gigawatt conversion exact?
Yes. Both exawatt and gigawatt are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
