About Converting Exawatts to Hectowatts
Exawatt and Hectowatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Exawatt is 1000000000000000000 watt units, and hectowatt is 100 watt units.
Formula
hectowatts = exawatts × 1e+16
This factor comes from each unit's defined relationship to the category's base unit: 1 exawatt equals 1e+18 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct exawatt-to-hectowatt factor of 1e+16.
Simple example
1 EW × 1e+16 = 1e+16 hW
1 exawatt = 1e+16 hectowatts.
Real-world example
100 EW × 1e+16 = 1e+18 hW
100 exawatts = 1e+18 hectowatts.
Conversion table
| Exawatt (EW) | Hectowatt (hW) |
|---|---|
| 1 EW | 1e+16 hW |
| 10 EW | 1e+17 hW |
| 100 EW | 1e+18 hW |
| 500 EW | 5e+18 hW |
| 1,000 EW | 1e+19 hW |
| 5,000 EW | 5e+19 hW |
Reverse conversion: Hectowatt to Exawatt
1e+16 hW × 1e-16 = 1 EW
1e+16 hectowatts = 1 exawatt.
exawatts = hectowatts × 1e-16

Frequently asked questions
How many hectowatts are in 1 exawatt?
1 exawatt equals 1e+16 hectowatts, using the exact defined conversion factor rather than an estimate.
How do I convert exawatt to hectowatt?
Multiply the exawatt value by 1e+16. The converter above does this instantly to whatever precision you set.
How do I convert hectowatt back to exawatt?
Use the reverse factor: 1 hectowatt equals 1e-16 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 power.
What is a hectowatt?
Hectowatt (hW) is a unit of power.
Is the exawatt to hectowatt conversion exact?
Yes. Both exawatt and hectowatt are defined by fixed standards rather than physical artifacts, so the factor of 1e+16 used above is exact to as many digits as you choose to display.
