About Converting Petawatts to Hectowatts
Petawatt 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: Petawatt is 1000000000000000 watt units, and hectowatt is 100 watt units.
Formula
hectowatts = petawatts × 1e+13
This factor comes from each unit's defined relationship to the category's base unit: 1 petawatt equals 1e+15 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct petawatt-to-hectowatt factor of 1e+13.
Simple example
1 PW × 1e+13 = 1e+13 hW
1 petawatt = 1e+13 hectowatts.
Real-world example
100 PW × 1e+13 = 1e+15 hW
100 petawatts = 1e+15 hectowatts.
Conversion table
| Petawatt (PW) | Hectowatt (hW) |
|---|---|
| 1 PW | 1e+13 hW |
| 10 PW | 1e+14 hW |
| 100 PW | 1e+15 hW |
| 500 PW | 5e+15 hW |
| 1,000 PW | 1e+16 hW |

Reverse conversion: Hectowatt to Petawatt
1e+13 hW × 1e-13 = 1 PW
1e+13 hectowatts = 1 petawatt.
petawatts = hectowatts × 1e-13
