About Converting Terasiemens to Petasiemens
Terasiemens 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: Terasiemens is 1000000000000 siemens units, and petasiemens is 1000000000000000 siemens units.
Formula
petasiemens = terasiemens × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 terasiemens equals 1e+12 base units, and 1 petasiemens equals 1e+15 base units, so dividing one by the other gives the direct terasiemens-to-petasiemens factor of 0.001.
Simple example
1 TS × 0.001 = 0.001 PS
1 terasiemens = 0.001 petasiemens.
Real-world example
120 TS × 0.001 = 0.12 PS
120 terasiemens = 0.12 petasiemens.

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