About Converting Terawatts to Decawatts
Terawatt and Decawatt 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: Terawatt is 1000000000000 watt units, and decawatt is 10 watt units.
Formula
decawatts = terawatts × 100000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 terawatt equals 1e+12 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct terawatt-to-decawatt factor of 100000000000.
Simple example
1 TW × 100000000000 = 100,000,000,000 daW
1 terawatt = 100,000,000,000 decawatts.
Real-world example
100 TW × 100000000000 = 1e+13 daW
100 terawatts = 1e+13 decawatts.

Reverse conversion: Decawatt to Terawatt
1 daW × 1e-11 = 1e-11 TW
1 decawatt = 1e-11 terawatts.
terawatts = decawatts × 1e-11

Frequently asked questions
How many decawatts are in 1 terawatt?
1 terawatt equals 100,000,000,000 decawatts, using the exact defined conversion factor rather than an estimate.
How do I convert terawatt to decawatt?
Multiply the terawatt value by 100000000000. The converter above does this instantly to whatever precision you set.
How do I convert decawatt back to terawatt?
Use the reverse factor: 1 decawatt equals 1e-11 terawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a terawatt?
Terawatt (TW) is a unit of engineering.
What is a decawatt?
Decawatt (daW) is a unit of engineering.
Is the terawatt to decawatt conversion exact?
Yes. Both terawatt and decawatt are defined by fixed standards rather than physical artifacts, so the factor of 100000000000 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.
