About Converting Petafarads to Decifarads
Petafarad and Decifarad 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: Petafarad is 1000000000000000 farad units, and decifarad is 0.1 farad units.
Formula
decifarads = petafarads × 1e+16
This factor comes from each unit's defined relationship to the category's base unit: 1 petafarad equals 1e+15 base units, and 1 decifarad equals 0.1 base units, so dividing one by the other gives the direct petafarad-to-decifarad factor of 1e+16.
Simple example
1 PF × 1e+16 = 1e+16 dF
1 petafarad = 1e+16 decifarads.
Real-world example
120 PF × 1e+16 = 1.2e+18 dF
120 petafarads = 1.2e+18 decifarads.

Reverse conversion: Decifarad to Petafarad
1e+16 dF × 1e-16 = 1 PF
1e+16 decifarads = 1 petafarad.
petafarads = decifarads × 1e-16

Frequently asked questions
How many decifarads are in 1 petafarad?
1 petafarad equals 1e+16 decifarads, using the exact defined conversion factor rather than an estimate.
How do I convert petafarad to decifarad?
Multiply the petafarad value by 1e+16. The converter above does this instantly to whatever precision you set.
How do I convert decifarad back to petafarad?
Use the reverse factor: 1 decifarad equals 1e-16 petafarads. You can also use the swap control in the converter above to flip the direction instantly.
What is a petafarad?
Petafarad (PF) is a unit of electricity.
What is a decifarad?
Decifarad (dF) is a unit of electricity.
Is the petafarad to decifarad conversion exact?
Yes. Both petafarad and decifarad 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.
