Context values
Some unit families need one extra value for a physically accurate result.
Megawatt is 1000000 watt units.
Result = input x 0.1 / 1e+6.

About Converting Deciwatts to Megawatts
Deciwatt and Megawatt both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. 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
120 dW × 1e-7 = 0.000012 MW
120 deciwatts = 0.000012 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 electricity.
What is a megawatt?
Megawatt (MW) is a unit of electricity.
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.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
