About Converting Microsiemens to Kilosiemens
Microsiemens and Kilosiemens 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 kilosiemens is 1000 siemens units.
Formula
kilosiemens = microsiemens × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 microsiemens equals 0.000001 base units, and 1 kilosiemens equals 1000 base units, so dividing one by the other gives the direct microsiemens-to-kilosiemens factor of 1e-9.
Simple example
1 uS × 1e-9 = 1e-9 kS
1 microsiemens = 1e-9 kilosiemens.
Real-world example
120 uS × 1e-9 = 1.2e-7 kS
120 microsiemens = 1.2e-7 kilosiemens.

Frequently asked questions
How many kilosiemens are in 1 microsiemens?
1 microsiemens equals 1e-9 kilosiemens, using the exact defined conversion factor rather than an estimate.
How do I convert microsiemens to kilosiemens?
Multiply the microsiemens value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert kilosiemens back to microsiemens?
Use the reverse factor: 1 kilosiemens equals 1,000,000,000 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 kilosiemens?
Kilosiemens (kS) is a unit of electricity.
Is the microsiemens to kilosiemens conversion exact?
Yes. Both microsiemens and kilosiemens are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 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.
