About Converting Nanowatts to Hectowatts
Nanowatt and Hectowatt 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: Nanowatt is 1e-9 watt units, and hectowatt is 100 watt units.
Formula
hectowatts = nanowatts × 1e-11
This factor comes from each unit's defined relationship to the category's base unit: 1 nanowatt equals 1e-9 base units, and 1 hectowatt equals 100 base units, so dividing one by the other gives the direct nanowatt-to-hectowatt factor of 1e-11.
Simple example
1 nW × 1e-11 = 1e-11 hW
1 nanowatt = 1e-11 hectowatts.
Real-world example
100 nW × 1e-11 = 1e-9 hW
100 nanowatts = 1e-9 hectowatts.
Conversion table
| Nanowatt (nW) | Hectowatt (hW) |

Reverse conversion: Hectowatt to Nanowatt
1e-11 hW × 100000000000 = 1 nW
1e-11 hectowatts = 1 nanowatts.
nanowatts = hectowatts × 100000000000

Frequently asked questions
How many hectowatts are in 1 nanowatt?
1 nanowatt equals 1e-11 hectowatts, using the exact defined conversion factor rather than an estimate.
How do I convert nanowatt to hectowatt?
Multiply the nanowatt value by 1e-11. The converter above does this instantly to whatever precision you set.
How do I convert hectowatt back to nanowatt?
Use the reverse factor: 1 hectowatt equals 100,000,000,000 nanowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanowatt?
Nanowatt (nW) is a unit of engineering.
What is a hectowatt?
Hectowatt (hW) is a unit of engineering.
Is the nanowatt to hectowatt conversion exact?
Yes. Both nanowatt and hectowatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-11 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.
