Context values
Some unit families need one extra value for a physically accurate result.
Milliwatt is 0.001 watt units.
Result = input x 10 / 0.001.

About Converting Decawatts to Milliwatts
Decawatt and Milliwatt 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: Decawatt is 10 watt units, and milliwatt is 0.001 watt units.
Formula
milliwatts = decawatts × 10000
This factor comes from each unit's defined relationship to the category's base unit: 1 decawatt equals 10 base units, and 1 milliwatt equals 0.001 base units, so dividing one by the other gives the direct decawatt-to-milliwatt factor of 10000.
Simple example
1 daW × 10000 = 10,000 mW
1 decawatt = 10,000 milliwatts.
Real-world example
120 daW × 10000 = 1,200,000 mW
120 decawatts = 1,200,000 milliwatts.

Reverse conversion: Milliwatt to Decawatt
1 mW × 0.0001 = 0.0001 daW
1 milliwatt = 0.0001 decawatts.
decawatts = milliwatts × 0.0001

Frequently asked questions
How many milliwatts are in 1 decawatt?
1 decawatt equals 10,000 milliwatts, using the exact defined conversion factor rather than an estimate.
How do I convert decawatt to milliwatt?
Multiply the decawatt value by 10000. The converter above does this instantly to whatever precision you set.
How do I convert milliwatt back to decawatt?
Use the reverse factor: 1 milliwatt equals 0.0001 decawatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a decawatt?
Decawatt (daW) is a unit of electricity.
What is a milliwatt?
Milliwatt (mW) is a unit of electricity.
Is the decawatt to milliwatt conversion exact?
Yes. Both decawatt and milliwatt are defined by fixed standards rather than physical artifacts, so the factor of 10000 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.
