About Converting Centiohms to Milliohms
Centiohm and Milliohm 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: Centiohm is 0.01 ohm units, and milliohm is 0.001 ohm units.
Formula
milliohms = centiohms × 10
This factor comes from each unit's defined relationship to the category's base unit: 1 centiohm equals 0.01 base units, and 1 milliohm equals 0.001 base units, so dividing one by the other gives the direct centiohm-to-milliohm factor of 10.
Simple example
1 cOhm × 10 = 10 mOhm
1 centiohm = 10 milliohms.
Real-world example
120 cOhm × 10 = 1,200 mOhm
120 centiohms = 1,200 milliohms.

Reverse conversion: Milliohm to Centiohm
10 mOhm × 0.1 = 1 cOhm
10 milliohms = 1 centiohm.
centiohms = milliohms × 0.1

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