About Converting Megaohms to Centiohms
Megaohm 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: Megaohm is 1000000 ohm units, and centiohm is 0.01 ohm units.
Formula
centiohms = megaohms × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megaohm equals 1000000 base units, and 1 centiohm equals 0.01 base units, so dividing one by the other gives the direct megaohm-to-centiohm factor of 100000000.
Simple example
1 MOhm × 100000000 = 100,000,000 cOhm
1 megaohm = 100,000,000 centiohms.
Real-world example
120 MOhm × 100000000 = 12,000,000,000 cOhm
120 megaohms = 12,000,000,000 centiohms.

Frequently asked questions
How many centiohms are in 1 megaohm?
1 megaohm equals 100,000,000 centiohms, using the exact defined conversion factor rather than an estimate.
How do I convert megaohm to centiohm?
Multiply the megaohm value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert centiohm back to megaohm?
Use the reverse factor: 1 centiohm equals 1e-8 megaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a megaohm?
Megaohm (MOhm) is a unit of electricity.
What is a centiohm?
Centiohm (cOhm) is a unit of electricity.
Is the megaohm to centiohm conversion exact?
Yes. Both megaohm and centiohm are defined by fixed standards rather than physical artifacts, so the factor of 100000000 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.
