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.
Decawatt is 10 watt units.
Result = input x 0.001 / 10.

About Converting Milliwatts to Decawatts
Milliwatt and Decawatt 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: Milliwatt is 0.001 watt units, and decawatt is 10 watt units.
Formula
decawatts = milliwatts × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 milliwatt equals 0.001 base units, and 1 decawatt equals 10 base units, so dividing one by the other gives the direct milliwatt-to-decawatt factor of 0.0001.
Simple example
1 mW × 0.0001 = 0.0001 daW
1 milliwatt = 0.0001 decawatts.
Real-world example
120 mW × 0.0001 = 0.012 daW
120 milliwatts = 0.012 decawatts.

Reverse conversion: Decawatt to Milliwatt
0.0001 daW × 10000 = 1 mW
0.0001 decawatts = 1 milliwatt.
milliwatts = decawatts × 10000

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