About Converting Megawatts to Deciwatts
Megawatt and Deciwatt both describe power output, and the conversion is a routine part of comparing an engine or motor's spec sheet across countries that use different power units. Specifically: Megawatt is 1000000 watt units, and deciwatt is 0.1 watt units.
Formula
deciwatts = megawatts × 10000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megawatt equals 1000000 base units, and 1 deciwatt equals 0.1 base units, so dividing one by the other gives the direct megawatt-to-deciwatt factor of 10000000.
Simple example
1 MW × 10000000 = 10,000,000 dW
1 megawatt = 10,000,000 deciwatts.
Real-world example
100 MW × 10000000 = 1,000,000,000 dW
100 megawatts = 1,000,000,000 deciwatts.

Reverse conversion: Deciwatt to Megawatt
1 dW × 1e-7 = 1e-7 MW
1 deciwatt = 1e-7 megawatts.
megawatts = deciwatts × 1e-7

Frequently asked questions
How many deciwatts are in 1 megawatt?
1 megawatt equals 10,000,000 deciwatts, using the exact defined conversion factor rather than an estimate.
How do I convert megawatt to deciwatt?
Multiply the megawatt value by 10000000. The converter above does this instantly to whatever precision you set.
How do I convert deciwatt back to megawatt?
Use the reverse factor: 1 deciwatt equals 1e-7 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 power.
What is a deciwatt?
Deciwatt (dW) is a unit of power.
Is the megawatt to deciwatt conversion exact?
Yes. Both megawatt and deciwatt are defined by fixed standards rather than physical artifacts, so the factor of 10000000 used above is exact to as many digits as you choose to display.
