About Converting Attofarads to Centifarads
Attofarad and Centifarad 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 centifarad is 0.01 farad units.
Formula
centifarads = attofarads × 1e-16
This factor comes from each unit's defined relationship to the category's base unit: 1 attofarad equals 1e-18 base units, and 1 centifarad equals 0.01 base units, so dividing one by the other gives the direct attofarad-to-centifarad factor of 1e-16.
Simple example
1 aF × 1e-16 = 1e-16 cF
1 attofarad = 1e-16 centifarads.
Real-world example
120 aF × 1e-16 = 1.2e-14 cF
120 attofarads = 1.2e-14 centifarads.

Frequently asked questions
How many centifarads are in 1 attofarad?
1 attofarad equals 1e-16 centifarads, using the exact defined conversion factor rather than an estimate.
How do I convert attofarad to centifarad?
Multiply the attofarad value by 1e-16. The converter above does this instantly to whatever precision you set.
How do I convert centifarad back to attofarad?
Use the reverse factor: 1 centifarad equals 1e+16 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 centifarad?
Centifarad (cF) is a unit of electricity.
Is the attofarad to centifarad conversion exact?
Yes. Both attofarad and centifarad are defined by fixed standards rather than physical artifacts, so the factor of 1e-16 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.
