About Converting Attofarads to Picofarads
Attofarad and Picofarad 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: Attofarad is 1e-18 farad units, and picofarad is 1e-12 farad units.
Formula
picofarads = attofarads × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 attofarad equals 1e-18 base units, and 1 picofarad equals 1e-12 base units, so dividing one by the other gives the direct attofarad-to-picofarad factor of 0.000001.
Simple example
1 aF × 0.000001 = 0.000001 pF
1 attofarad = 0.000001 picofarads.
Real-world example
120 aF × 0.000001 = 0.00012 pF
120 attofarads = 0.00012 picofarads.

Reverse conversion: Picofarad to Attofarad
0.000001 pF × 1000000 = 1 aF
0.000001 picofarads = 1 attofarads.
attofarads = picofarads × 1000000

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