Context values
Some unit families need one extra value for a physically accurate result.
Deciohm is 0.1 ohm units.
Result = input x 0.001 / 0.1.

About Converting Milliohms to Deciohms
Milliohm and Deciohm 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 deciohm is 0.1 ohm units.
Formula
deciohms = milliohms × 0.01
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 deciohm equals 0.1 base units, so dividing one by the other gives the direct milliohm-to-deciohm factor of 0.01.
Simple example
1 mOhm × 0.01 = 0.01 dOhm
1 milliohm = 0.01 deciohms.
Real-world example
120 mOhm × 0.01 = 1.2 dOhm
120 milliohms = 1.2 deciohms.

Reverse conversion: Deciohm to Milliohm
0.01 dOhm × 100 = 1 mOhm
0.01 deciohms = 1 milliohm.
milliohms = deciohms × 100

Frequently asked questions
How many deciohms are in 1 milliohm?
1 milliohm equals 0.01 deciohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to deciohm?
Multiply the milliohm value by 0.01. The converter above does this instantly to whatever precision you set.
How do I convert deciohm back to milliohm?
Use the reverse factor: 1 deciohm equals 100 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 deciohm?
Deciohm (dOhm) is a unit of electricity.
Is the milliohm to deciohm conversion exact?
Yes. Both milliohm and deciohm are defined by fixed standards rather than physical artifacts, so the factor of 0.01 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.
