Context values
Some unit families need one extra value for a physically accurate result.
Deciwatt is 0.1 watt units.
Result = input x 0.01 / 0.1.

About Converting Centiwatts to Deciwatts
Centiwatt 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: Centiwatt is 0.01 watt units, and deciwatt is 0.1 watt units.
Formula
deciwatts = centiwatts × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 centiwatt equals 0.01 base units, and 1 deciwatt equals 0.1 base units, so dividing one by the other gives the direct centiwatt-to-deciwatt factor of 0.1.
Simple example
1 cW × 0.1 = 0.1 dW
1 centiwatt = 0.1 deciwatts.
Real-world example
120 cW × 0.1 = 12 dW
120 centiwatts = 12 deciwatts.

Reverse conversion: Deciwatt to Centiwatt
0.1 dW × 10 = 1 cW
0.1 deciwatts = 1 centiwatts.
centiwatts = deciwatts × 10

Frequently asked questions
How many deciwatts are in 1 centiwatt?
1 centiwatt equals 0.1 deciwatts, using the exact defined conversion factor rather than an estimate.
How do I convert centiwatt to deciwatt?
Multiply the centiwatt value by 0.1. The converter above does this instantly to whatever precision you set.
How do I convert deciwatt back to centiwatt?
Use the reverse factor: 1 deciwatt equals 10 centiwatts. You can also use the swap control in the converter above to flip the direction instantly.
What is a centiwatt?
Centiwatt (cW) is a unit of electricity.
What is a deciwatt?
Deciwatt (dW) is a unit of electricity.
Is the centiwatt to deciwatt conversion exact?
Yes. Both centiwatt and deciwatt are defined by fixed standards rather than physical artifacts, so the factor of 0.1 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.
