About Converting Hectowatts to Terawatts
Hectowatt and Terawatt 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: Hectowatt is 100 watt units, and terawatt is 1000000000000 watt units.
Formula
terawatts = hectowatts × 1e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 hectowatt equals 100 base units, and 1 terawatt equals 1e+12 base units, so dividing one by the other gives the direct hectowatt-to-terawatt factor of 1e-10.
Simple example
1 hW × 1e-10 = 1e-10 TW
1 hectowatt = 1e-10 terawatts.
Real-world example
100 hW × 1e-10 = 1e-8 TW
100 hectowatts = 1e-8 terawatts.

Reverse conversion: Terawatt to Hectowatt
1e-10 TW × 10000000000 = 1 hW
1e-10 terawatts = 1 hectowatt.
hectowatts = terawatts × 10000000000

Frequently asked questions
How many terawatts are in 1 hectowatt?
1 hectowatt equals 1e-10 terawatts, using the exact defined conversion factor rather than an estimate.
How do I convert hectowatt to terawatt?
Multiply the hectowatt value by 1e-10. The converter above does this instantly to whatever precision you set.
How do I convert terawatt back to hectowatt?
Use the reverse factor: 1 terawatt equals 10,000,000,000 hectowatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectowatt?
Hectowatt (hW) is a unit of engineering.
What is a terawatt?
Terawatt (TW) is a unit of engineering.
Is the hectowatt to terawatt conversion exact?
Yes. Both hectowatt and terawatt are defined by fixed standards rather than physical artifacts, so the factor of 1e-10 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.
