About Converting Centiohms to Exaohms
Centiohm and Exaohm 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 exaohm is 1000000000000000000 ohm units.
Formula
exaohms = centiohms × 1e-20
This factor comes from each unit's defined relationship to the category's base unit: 1 centiohm equals 0.01 base units, and 1 exaohm equals 1e+18 base units, so dividing one by the other gives the direct centiohm-to-exaohm factor of 1e-20.
Simple example
1 cOhm × 1e-20 = 1e-20 EOhm
1 centiohm = 1e-20 exaohms.
Real-world example
120 cOhm × 1e-20 = 1.2e-18 EOhm
120 centiohms = 1.2e-18 exaohms.

Reverse conversion: Exaohm to Centiohm
1e-20 EOhm × 1e+20 = 1 cOhm
1e-20 exaohms = 1 centiohm.
centiohms = exaohms × 1e+20

Frequently asked questions
How many exaohms are in 1 centiohm?
1 centiohm equals 1e-20 exaohms, using the exact defined conversion factor rather than an estimate.
How do I convert centiohm to exaohm?
Multiply the centiohm value by 1e-20. The converter above does this instantly to whatever precision you set.
How do I convert exaohm back to centiohm?
Use the reverse factor: 1 exaohm equals 1e+20 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 exaohm?
Exaohm (EOhm) is a unit of electricity.
Is the centiohm to exaohm conversion exact?
Yes. Both centiohm and exaohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-20 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.
