About Converting Petasiemens to Attosiemens
Petasiemens and Attosiemens 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: Petasiemens is 1000000000000000 siemens units, and attosiemens is 1e-18 siemens units.
Formula
attosiemens = petasiemens × 1e+33
This factor comes from each unit's defined relationship to the category's base unit: 1 petasiemens equals 1e+15 base units, and 1 attosiemens equals 1e-18 base units, so dividing one by the other gives the direct petasiemens-to-attosiemens factor of 1e+33.
Simple example
1 PS × 1e+33 = 1e+33 aS
1 petasiemens = 1e+33 attosiemens.
Real-world example
120 PS × 1e+33 = 1.2e+35 aS
120 petasiemens = 1.2e+35 attosiemens.

Frequently asked questions
How many attosiemens are in 1 petasiemens?
1 petasiemens equals 1e+33 attosiemens, using the exact defined conversion factor rather than an estimate.
How do I convert petasiemens to attosiemens?
Multiply the petasiemens value by 1e+33. The converter above does this instantly to whatever precision you set.
How do I convert attosiemens back to petasiemens?
Use the reverse factor: 1 attosiemens equals 1e-33 petasiemens. You can also use the swap control in the converter above to flip the direction instantly.
What is a petasiemens?
Petasiemens (PS) is a unit of electricity.
What is a attosiemens?
Attosiemens (aS) is a unit of electricity.
Is the petasiemens to attosiemens conversion exact?
Yes. Both petasiemens and attosiemens are defined by fixed standards rather than physical artifacts, so the factor of 1e+33 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.
