About Converting Centiohms to Hectoohms
Centiohm and Hectoohm 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 hectoohm is 100 ohm units.
Formula
hectoohms = centiohms × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 centiohm equals 0.01 base units, and 1 hectoohm equals 100 base units, so dividing one by the other gives the direct centiohm-to-hectoohm factor of 0.0001.
Simple example
1 cOhm × 0.0001 = 0.0001 hOhm
1 centiohm = 0.0001 hectoohms.
Real-world example
120 cOhm × 0.0001 = 0.012 hOhm
120 centiohms = 0.012 hectoohms.

Reverse conversion: Hectoohm to Centiohm
0.0001 hOhm × 10000 = 1 cOhm
0.0001 hectoohms = 1 centiohm.
centiohms = hectoohms × 10000

Frequently asked questions
How many hectoohms are in 1 centiohm?
1 centiohm equals 0.0001 hectoohms, using the exact defined conversion factor rather than an estimate.
How do I convert centiohm to hectoohm?
Multiply the centiohm value by 0.0001. The converter above does this instantly to whatever precision you set.
How do I convert hectoohm back to centiohm?
Use the reverse factor: 1 hectoohm equals 10,000 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 hectoohm?
Hectoohm (hOhm) is a unit of electricity.
Is the centiohm to hectoohm conversion exact?
Yes. Both centiohm and hectoohm are defined by fixed standards rather than physical artifacts, so the factor of 0.0001 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.
