About Converting Hectoohms to Centiohms
Hectoohm 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: Hectoohm is 100 ohm units, and centiohm is 0.01 ohm units.
Formula
centiohms = hectoohms × 10000
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoohm equals 100 base units, and 1 centiohm equals 0.01 base units, so dividing one by the other gives the direct hectoohm-to-centiohm factor of 10000.
Simple example
1 hOhm × 10000 = 10,000 cOhm
1 hectoohm = 10,000 centiohms.
Real-world example
120 hOhm × 10000 = 1,200,000 cOhm
120 hectoohms = 1,200,000 centiohms.

Frequently asked questions
How many centiohms are in 1 hectoohm?
1 hectoohm equals 10,000 centiohms, using the exact defined conversion factor rather than an estimate.
How do I convert hectoohm to centiohm?
Multiply the hectoohm value by 10000. The converter above does this instantly to whatever precision you set.
How do I convert centiohm back to hectoohm?
Use the reverse factor: 1 centiohm equals 0.0001 hectoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a hectoohm?
Hectoohm (hOhm) is a unit of electricity.
What is a centiohm?
Centiohm (cOhm) is a unit of electricity.
Is the hectoohm to centiohm conversion exact?
Yes. Both hectoohm and centiohm are defined by fixed standards rather than physical artifacts, so the factor of 10000 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.
