About Converting Nanosiemens to Microsiemens
Nanosiemens and Microsiemens 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: Nanosiemens is 1e-9 siemens units, and microsiemens is 0.000001 siemens units.
Formula
microsiemens = nanosiemens × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 nanosiemens equals 1e-9 base units, and 1 microsiemens equals 0.000001 base units, so dividing one by the other gives the direct nanosiemens-to-microsiemens factor of 0.001.
Simple example
1 nS × 0.001 = 0.001 uS
1 nanosiemens = 0.001 microsiemens.
Real-world example
120 nS × 0.001 = 0.12 uS
120 nanosiemens = 0.12 microsiemens.

Reverse conversion: Microsiemens to Nanosiemens
0.001 uS × 1000 = 1 nS
0.001 microsiemens = 1 nanosiemens.
nanosiemens = microsiemens × 1000

Frequently asked questions
How many microsiemens are in 1 nanosiemens?
1 nanosiemens equals 0.001 microsiemens, using the exact defined conversion factor rather than an estimate.
How do I convert nanosiemens to microsiemens?
Multiply the nanosiemens value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert microsiemens back to nanosiemens?
Use the reverse factor: 1 microsiemens equals 1,000 nanosiemens. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanosiemens?
Nanosiemens (nS) is a unit of electricity.
What is a microsiemens?
Microsiemens (uS) is a unit of electricity.
Is the nanosiemens to microsiemens conversion exact?
Yes. Both nanosiemens and microsiemens 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.
