About Converting Gigawatts to Deciwatts
Gigawatt and Deciwatt 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: Gigawatt is 1000000000 watt units, and deciwatt is 0.1 watt units.
Formula
deciwatts = gigawatts × 10000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gigawatt equals 1000000000 base units, and 1 deciwatt equals 0.1 base units, so dividing one by the other gives the direct gigawatt-to-deciwatt factor of 10000000000.
Simple example
1 GW × 10000000000 = 10,000,000,000 dW
1 gigawatt = 10,000,000,000 deciwatts.
Real-world example
100 GW × 10000000000 = 1e+12 dW
100 gigawatts = 1e+12 deciwatts.

Reverse conversion: Deciwatt to Gigawatt
1 dW × 1e-10 = 1e-10 GW
1 deciwatt = 1e-10 gigawatts.
gigawatts = deciwatts × 1e-10

Frequently asked questions
How many deciwatts are in 1 gigawatt?
1 gigawatt equals 10,000,000,000 deciwatts, using the exact defined conversion factor rather than an estimate.
How do I convert gigawatt to deciwatt?
Multiply the gigawatt value by 10000000000. The converter above does this instantly to whatever precision you set.
How do I convert deciwatt back to gigawatt?
Use the reverse factor: 1 deciwatt equals 1e-10 gigawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigawatt?
Gigawatt (GW) is a unit of engineering.
What is a deciwatt?
Deciwatt (dW) is a unit of engineering.
Is the gigawatt to deciwatt conversion exact?
Yes. Both gigawatt and deciwatt are defined by fixed standards rather than physical artifacts, so the factor of 10000000000 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.
