About Converting Picofarads to Attofarads
Picofarad and Attofarad 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: Picofarad is 1e-12 farad units, and attofarad is 1e-18 farad units.
Formula
attofarads = picofarads × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 picofarad equals 1e-12 base units, and 1 attofarad equals 1e-18 base units, so dividing one by the other gives the direct picofarad-to-attofarad factor of 1000000.
Simple example
1 pF × 1000000 = 1,000,000 aF
1 picofarad = 1,000,000 attofarads.
Real-world example
120 pF × 1000000 = 120,000,000 aF
120 picofarads = 120,000,000 attofarads.

Reverse conversion: Attofarad to Picofarad
1 aF × 0.000001 = 0.000001 pF
1 attofarad = 0.000001 picofarads.
picofarads = attofarads × 0.000001

Frequently asked questions
How many attofarads are in 1 picofarad?
1 picofarad equals 1,000,000 attofarads, using the exact defined conversion factor rather than an estimate.
How do I convert picofarad to attofarad?
Multiply the picofarad value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert attofarad back to picofarad?
Use the reverse factor: 1 attofarad equals 0.000001 picofarads. You can also use the swap control in the converter above to flip the direction instantly.
What is a picofarad?
Picofarad (pF) is a unit of electricity.
What is a attofarad?
Attofarad (aF) is a unit of electricity.
Is the picofarad to attofarad conversion exact?
Yes. Both picofarad and attofarad 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.
