About Converting Milliohms to Hectoohms
Milliohm 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: Milliohm is 0.001 ohm units, and hectoohm is 100 ohm units.
Formula
hectoohms = milliohms × 0.00001
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 hectoohm equals 100 base units, so dividing one by the other gives the direct milliohm-to-hectoohm factor of 0.00001.
Simple example
1 mOhm × 0.00001 = 0.00001 hOhm
1 milliohm = 0.00001 hectoohms.
Real-world example
120 mOhm × 0.00001 = 0.0012 hOhm
120 milliohms = 0.0012 hectoohms.

Reverse conversion: Hectoohm to Milliohm
0.00001 hOhm × 100000 = 1 mOhm
0.00001 hectoohms = 1 milliohm.
milliohms = hectoohms × 100000

Frequently asked questions
How many hectoohms are in 1 milliohm?
1 milliohm equals 0.00001 hectoohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to hectoohm?
Multiply the milliohm value by 0.00001. The converter above does this instantly to whatever precision you set.
How do I convert hectoohm back to milliohm?
Use the reverse factor: 1 hectoohm equals 100,000 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 hectoohm?
Hectoohm (hOhm) is a unit of electricity.
Is the milliohm to hectoohm conversion exact?
Yes. Both milliohm and hectoohm are defined by fixed standards rather than physical artifacts, so the factor of 0.00001 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.
