About Converting Nanoohms to Microohms
Nanoohm 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: Nanoohm is 1e-9 ohm units, and microohm is 0.000001 ohm units.
Formula
microohms = nanoohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoohm equals 1e-9 base units, and 1 microohm equals 0.000001 base units, so dividing one by the other gives the direct nanoohm-to-microohm factor of 0.001.
Simple example
1 nOhm × 0.001 = 0.001 uOhm
1 nanoohm = 0.001 microohms.
Real-world example
120 nOhm × 0.001 = 0.12 uOhm
120 nanoohms = 0.12 microohms.

Reverse conversion: Microohm to Nanoohm
0.001 uOhm × 1000 = 1 nOhm
0.001 microohms = 1 nanoohm.
nanoohms = microohms × 1000

Frequently asked questions
How many microohms are in 1 nanoohm?
1 nanoohm equals 0.001 microohms, using the exact defined conversion factor rather than an estimate.
How do I convert nanoohm to microohm?
Multiply the nanoohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert microohm back to nanoohm?
Use the reverse factor: 1 microohm equals 1,000 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 microohm?
Microohm (uOhm) is a unit of electricity.
Is the nanoohm to microohm conversion exact?
Yes. Both nanoohm and microohm are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
