Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Deciwatt is 0.1 watt units.
Result = input x 1e+6 / 0.1.

About Converting Megawatts to Deciwatts
Megawatt and Deciwatt 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: 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
120 MW × 10000000 = 1,200,000,000 dW
120 megawatts = 1,200,000,000 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 electricity.
What is a deciwatt?
Deciwatt (dW) is a unit of electricity.
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.
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.
