About Converting Deciwatts to Megawatts
Deciwatt and Megawatt 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: Deciwatt is 0.1 watt units, and megawatt is 1000000 watt units.
Formula
megawatts = deciwatts × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 deciwatt equals 0.1 base units, and 1 megawatt equals 1000000 base units, so dividing one by the other gives the direct deciwatt-to-megawatt factor of 1e-7.
Simple example
1 dW × 1e-7 = 1e-7 MW
1 deciwatt = 1e-7 megawatts.
Real-world example
100 dW × 1e-7 = 0.00001 MW
100 deciwatts = 0.00001 megawatts.

Reverse conversion: Megawatt to Deciwatt
1e-7 MW × 10000000 = 1 dW
1e-7 megawatts = 1 deciwatts.
deciwatts = megawatts × 10000000

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