About Converting Megaohms to Nanoohms
Megaohm and Nanoohm 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 nanoohm is 1e-9 ohm units.
Formula
nanoohms = megaohms × 1e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 megaohm equals 1000000 base units, and 1 nanoohm equals 1e-9 base units, so dividing one by the other gives the direct megaohm-to-nanoohm factor of 1e+15.
Simple example
1 MOhm × 1e+15 = 1e+15 nOhm
1 megaohm = 1e+15 nanoohms.
Real-world example
120 MOhm × 1e+15 = 1.2e+17 nOhm
120 megaohms = 1.2e+17 nanoohms.

Reverse conversion: Nanoohm to Megaohm
1e+15 nOhm × 1e-15 = 1 MOhm
1e+15 nanoohms = 1 megaohms.
megaohms = nanoohms × 1e-15

Frequently asked questions
How many nanoohms are in 1 megaohm?
1 megaohm equals 1e+15 nanoohms, using the exact defined conversion factor rather than an estimate.
How do I convert megaohm to nanoohm?
Multiply the megaohm value by 1e+15. The converter above does this instantly to whatever precision you set.
How do I convert nanoohm back to megaohm?
Use the reverse factor: 1 nanoohm equals 1e-15 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 nanoohm?
Nanoohm (nOhm) is a unit of electricity.
Is the megaohm to nanoohm conversion exact?
Yes. Both megaohm and nanoohm are defined by fixed standards rather than physical artifacts, so the factor of 1e+15 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.
