About Converting Picosiemens to Attosiemens
Picosiemens 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: Picosiemens is 1e-12 siemens units, and attosiemens is 1e-18 siemens units.
Formula
attosiemens = picosiemens × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 picosiemens equals 1e-12 base units, and 1 attosiemens equals 1e-18 base units, so dividing one by the other gives the direct picosiemens-to-attosiemens factor of 1000000.
Simple example
1 pS × 1000000 = 1,000,000 aS
1 picosiemens = 1,000,000 attosiemens.
Real-world example
120 pS × 1000000 = 120,000,000 aS
120 picosiemens = 120,000,000 attosiemens.

Frequently asked questions
How many attosiemens are in 1 picosiemens?
1 picosiemens equals 1,000,000 attosiemens, using the exact defined conversion factor rather than an estimate.
How do I convert picosiemens to attosiemens?
Multiply the picosiemens value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert attosiemens back to picosiemens?
Use the reverse factor: 1 attosiemens equals 0.000001 picosiemens. You can also use the swap control in the converter above to flip the direction instantly.
What is a picosiemens?
Picosiemens (pS) is a unit of electricity.
What is a attosiemens?
Attosiemens (aS) is a unit of electricity.
Is the picosiemens to attosiemens conversion exact?
Yes. Both picosiemens and attosiemens are defined by fixed standards rather than physical artifacts, so the factor of 1000000 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.
