About Converting Megawatts to Decawatts
Megawatt 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: Megawatt is 1000000 watt units, and decawatt is 10 watt units.
Formula
decawatts = megawatts × 100000
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct megawatt-to-decawatt factor of 100000.
Simple example
1 MW × 100000 = 100,000 daW
1 megawatt = 100,000 decawatts.
Real-world example
100 MW × 100000 = 10,000,000 daW
100 megawatts = 10,000,000 decawatts.

Frequently asked questions
How many decawatts are in 1 megawatt?
1 megawatt equals 100,000 decawatts, using the exact defined conversion factor rather than an estimate.
How do I convert megawatt to decawatt?
Multiply the megawatt value by 100000. The converter above does this instantly to whatever precision you set.
How do I convert decawatt back to megawatt?
Use the reverse factor: 1 decawatt equals 0.00001 megawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a megawatt?
Megawatt (MW) is a unit of engineering.
What is a decawatt?
Decawatt (daW) is a unit of engineering.
Is the megawatt to decawatt conversion exact?
Yes. Both megawatt and decawatt are defined by fixed standards rather than physical artifacts, so the factor of 100000 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.
