1 farad equals 1 volt
The conversion of 1 farad to volt results in 1 volt. This is because 1 farad is a unit of capacitance, which directly relates to voltage when considering charge stored.
Capacitance (farad) measures how much electric charge a capacitor can hold per unit voltage. Since 1 farad equals the amount of charge (in coulombs) per volt, when you have 1 farad of capacitance, it means 1 coulomb of charge creates 1 volt across the capacitor.

Conversion Formula
The formula to convert farads to volts is based on the relationship V = Q / C, where Q is charge in coulombs and C is capacitance in farads. When considering 1 coulomb charge, the voltage equals 1 divided by the capacitance. For example, if capacitance is 2 farads, voltage is 1/2 = 0.5 volts.
This works because capacitance indicates how much charge a capacitor can store per volt. Rearranging the formula shows that voltage depends inversely on capacitance when charge is fixed.
Conversion Example
- Convert 2 farads to volts:
- Using V = 1 / C, substitute 2 for C.
- V = 1 / 2 = 0.5 volts.
- Convert 0.5 farads to volts:
- V = 1 / 0.5 = 2 volts.
- Convert 10 farads to volts:
- V = 1 / 10 = 0.1 volts.
- Convert 0.1 farads to volts:
- V = 1 / 0.1 = 10 volts.
- Convert 5 farads to volts:
- V = 1 / 5 = 0.2 volts.

Conversion Definitions
Farad
The farad (F) measures a capacitor’s ability to store charge per unit voltage. One farad equals one coulomb of charge stored at one volt, representing the capacity of a device to hold electrical energy.
Volt
The volt (V) is the potential difference or electric pressure between two points. It indicates how much energy per unit charge is available, where one volt equals one joule of energy per coulomb of charge.
Conversion FAQs
Can I convert 1 farad directly to volts without knowing charge?
Yes, but only under the assumption that the charge stored is 1 coulomb. In that case, the voltage equals 1 divided by the capacitance, so for 1 farad, it equals 1 volt.
What happens to voltage if capacitance increases while charge remains same?
Voltage decreases when capacitance increases with constant charge because V = Q / C. So, more capacitance means less voltage for the same charge.
Is the conversion from farad to volt always inverse relation?
Yes, when charge is fixed, the voltage is inversely proportional to capacitance. Doubling the capacitance halves the voltage, and vice versa.
How do I determine voltage if I have a different charge than 1 coulomb?
You multiply the charge in coulombs by the reciprocal of the capacitance: V = Q / C. So, if charge is 2 coulombs and capacitance is 1 farad, voltage is 2 volts.
