About Converting Milliohms to Decaohms
Milliohm and Decaohm 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: Milliohm is 0.001 ohm units, and decaohm is 10 ohm units.
Formula
decaohms = milliohms × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 decaohm equals 10 base units, so dividing one by the other gives the direct milliohm-to-decaohm factor of 0.0001.
Simple example
1 mOhm × 0.0001 = 0.0001 daOhm
1 milliohm = 0.0001 decaohms.
Real-world example
120 mOhm × 0.0001 = 0.012 daOhm
120 milliohms = 0.012 decaohms.

Reverse conversion: Decaohm to Milliohm
0.0001 daOhm × 10000 = 1 mOhm
0.0001 decaohms = 1 milliohm.
milliohms = decaohms × 10000

Frequently asked questions
How many decaohms are in 1 milliohm?
1 milliohm equals 0.0001 decaohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to decaohm?
Multiply the milliohm value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert decaohm back to milliohm?
Use the reverse factor: 1 decaohm equals 10,000 milliohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliohm?
Milliohm (mOhm) is a unit of electricity.
What is a decaohm?
Decaohm (daOhm) is a unit of electricity.
Is the milliohm to decaohm conversion exact?
Yes. Both milliohm and decaohm 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.
