About Converting Hectoohms to Megaohms
Hectoohm and Megaohm 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 megaohm is 1000000 ohm units.
Formula
megaohms = hectoohms × 0.0001
This factor comes from each unit's defined relationship to the category's base unit: 1 hectoohm equals 100 base units, and 1 megaohm equals 1000000 base units, so dividing one by the other gives the direct hectoohm-to-megaohm factor of 0.0001.
Simple example
1 hOhm × 0.0001 = 0.0001 MOhm
1 hectoohm = 0.0001 megaohms.
Real-world example
120 hOhm × 0.0001 = 0.012 MOhm
120 hectoohms = 0.012 megaohms.

Reverse conversion: Megaohm to Hectoohm
0.0001 MOhm × 10000 = 1 hOhm
0.0001 megaohms = 1 hectoohm.
hectoohms = megaohms × 10000

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