Electricity Converter
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.
Siemens is the SI unit of conductance.
Result = input x 1e-6 / 1.

About Converting Microsiemens to Siemens
Microsiemens and Siemens 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: Microsiemens is 0.000001 siemens units, and siemens is the SI unit of conductance.
Formula
siemens = microsiemens × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 microsiemens equals 0.000001 base units, and 1 siemens equals 1 base unit, so dividing one by the other gives the direct microsiemens-to-siemens factor of 0.000001.
Simple example
1 uS × 0.000001 = 0.000001 S
1 microsiemens = 0.000001 siemens.
Real-world example
120 uS × 0.000001 = 0.00012 S
120 microsiemens = 0.00012 siemens.

Reverse conversion: Siemens to Microsiemens
0.000001 S × 1000000 = 1 uS
0.000001 siemens = 1 microsiemens.
microsiemens = siemens × 1000000

Frequently asked questions
How many siemens are in 1 microsiemens?
1 microsiemens equals 0.000001 siemens, using the exact defined conversion factor rather than an estimate.
How do I convert microsiemens to siemens?
Multiply the microsiemens value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert siemens back to microsiemens?
Use the reverse factor: 1 siemens equals 1,000,000 microsiemens. You can also use the swap control in the converter above to flip the direction instantly.
What is a microsiemens?
Microsiemens (uS) is a unit of electricity.
What is a siemens?
Siemens (S) is a unit of electricity.
Is the microsiemens to siemens conversion exact?
Yes. Both microsiemens and siemens 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.
