Farads To Amp Hours Formula

The following formula is used to convert Farads to Amp Hours.

AH = F * V / 3600

Variables:

  • AH is the electric charge or the amount of electric energy the capacitor can store, measured in Ampere Hours (Ah)
  • F is the capacitance of the capacitor, measured in Farads (F)
  • V is the voltage across the capacitor, measured in Volts (V)

To calculate the Ampere Hours, multiply the capacitance of the capacitor in Farads by the voltage across the capacitor in Volts. Then, divide the result by 3600 to convert the result from seconds to hours.
