Context values
Some unit families need one extra value for a physically accurate result.
Milliohm is 0.001 ohm units.
Result = input x 1e-9 / 0.001.

About Converting Nanoohms to Milliohms
Nanoohm and Milliohm 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: Nanoohm is 1e-9 ohm units, and milliohm is 0.001 ohm units.
Formula
milliohms = nanoohms × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoohm equals 1e-9 base units, and 1 milliohm equals 0.001 base units, so dividing one by the other gives the direct nanoohm-to-milliohm factor of 0.000001.
Simple example
1 nOhm × 0.000001 = 0.000001 mOhm
1 nanoohm = 0.000001 milliohms.
Real-world example
120 nOhm × 0.000001 = 0.00012 mOhm
120 nanoohms = 0.00012 milliohms.

Reverse conversion: Milliohm to Nanoohm
0.000001 mOhm × 1000000 = 1 nOhm
0.000001 milliohms = 1 nanoohm.
nanoohms = milliohms × 1000000

Frequently asked questions
How many milliohms are in 1 nanoohm?
1 nanoohm equals 0.000001 milliohms, using the exact defined conversion factor rather than an estimate.
How do I convert nanoohm to milliohm?
Multiply the nanoohm value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert milliohm back to nanoohm?
Use the reverse factor: 1 milliohm equals 1,000,000 nanoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanoohm?
Nanoohm (nOhm) is a unit of electricity.
What is a milliohm?
Milliohm (mOhm) is a unit of electricity.
Is the nanoohm to milliohm conversion exact?
Yes. Both nanoohm and milliohm are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
