About Converting Milliohms to Centiohms
Milliohm and Centiohm 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 centiohm is 0.01 ohm units.
Formula
centiohms = milliohms × 0.1
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 centiohm equals 0.01 base units, so dividing one by the other gives the direct milliohm-to-centiohm factor of 0.1.
Simple example
1 mOhm × 0.1 = 0.1 cOhm
1 milliohm = 0.1 centiohms.
Real-world example
120 mOhm × 0.1 = 12 cOhm
120 milliohms = 12 centiohms.

Frequently asked questions
How many centiohms are in 1 milliohm?
1 milliohm equals 0.1 centiohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to centiohm?
Multiply the milliohm value by 0.1. The converter above does this instantly to whatever precision you set.
How do I convert centiohm back to milliohm?
Use the reverse factor: 1 centiohm equals 10 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 centiohm?
Centiohm (cOhm) is a unit of electricity.
Is the milliohm to centiohm conversion exact?
Yes. Both milliohm and centiohm 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.
