About Converting Megaohms to Microohms
Megaohm and Microohm 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: Megaohm is 1000000 ohm units, and microohm is 0.000001 ohm units.
Formula
microohms = megaohms × 1e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 megaohm equals 1000000 base units, and 1 microohm equals 0.000001 base units, so dividing one by the other gives the direct megaohm-to-microohm factor of 1e+12.
Simple example
1 MOhm × 1e+12 = 1e+12 uOhm
1 megaohm = 1e+12 microohms.
Real-world example
120 MOhm × 1e+12 = 1.2e+14 uOhm
120 megaohms = 1.2e+14 microohms.

Reverse conversion: Microohm to Megaohm
1e+12 uOhm × 1e-12 = 1 MOhm
1e+12 microohms = 1 megaohm.
megaohms = microohms × 1e-12

Frequently asked questions
How many microohms are in 1 megaohm?
1 megaohm equals 1e+12 microohms, using the exact defined conversion factor rather than an estimate.
How do I convert megaohm to microohm?
Multiply the megaohm value by 1e+12. The converter above does this instantly to whatever precision you set.
How do I convert microohm back to megaohm?
Use the reverse factor: 1 microohm equals 1e-12 megaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a megaohm?
Megaohm (MOhm) is a unit of electricity.
What is a microohm?
Microohm (uOhm) is a unit of electricity.
Is the megaohm to microohm conversion exact?
Yes. Both megaohm and microohm are defined by fixed standards rather than physical artifacts, so the factor of 1e+12 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.
