About Converting Kilosiemens to Petasiemens
Kilosiemens and Petasiemens 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: Kilosiemens is 1000 siemens units, and petasiemens is 1000000000000000 siemens units.
Formula
petasiemens = kilosiemens × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 kilosiemens equals 1000 base units, and 1 petasiemens equals 1e+15 base units, so dividing one by the other gives the direct kilosiemens-to-petasiemens factor of 1e-12.
Simple example
1 kS × 1e-12 = 1e-12 PS
1 kilosiemens = 1e-12 petasiemens.
Real-world example
120 kS × 1e-12 = 1.2e-10 PS
120 kilosiemens = 1.2e-10 petasiemens.

Reverse conversion: Petasiemens to Kilosiemens
1e-12 PS × 1e+12 = 1 kS
1e-12 petasiemens = 1 kilosiemens.
kilosiemens = petasiemens × 1e+12

Frequently asked questions
How many petasiemens are in 1 kilosiemens?
1 kilosiemens equals 1e-12 petasiemens, using the exact defined conversion factor rather than an estimate.
How do I convert kilosiemens to petasiemens?
Multiply the kilosiemens value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert petasiemens back to kilosiemens?
Use the reverse factor: 1 petasiemens equals 1e+12 kilosiemens. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilosiemens?
Kilosiemens (kS) is a unit of electricity.
What is a petasiemens?
Petasiemens (PS) is a unit of electricity.
Is the kilosiemens to petasiemens conversion exact?
Yes. Both kilosiemens and petasiemens are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 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.
