Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Nanoohm is 1e-9 ohm units.
Result = input x 0.001 / 1e-9.

About Converting Milliohms to Nanoohms
Milliohm 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: Milliohm is 0.001 ohm units, and nanoohm is 1e-9 ohm units.
Formula
nanoohms = milliohms × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 nanoohm equals 1e-9 base units, so dividing one by the other gives the direct milliohm-to-nanoohm factor of 1000000.
Simple example
1 mOhm × 1000000 = 1,000,000 nOhm
1 milliohm = 1,000,000 nanoohms.
Real-world example
120 mOhm × 1000000 = 120,000,000 nOhm
120 milliohms = 120,000,000 nanoohms.

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

Frequently asked questions
How many nanoohms are in 1 milliohm?
1 milliohm equals 1,000,000 nanoohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to nanoohm?
Multiply the milliohm value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert nanoohm back to milliohm?
Use the reverse factor: 1 nanoohm equals 0.000001 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 nanoohm?
Nanoohm (nOhm) is a unit of electricity.
Is the milliohm to nanoohm conversion exact?
Yes. Both milliohm and nanoohm are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
