Enter the resistance and frequency into the calculator to determine the capacitance. This calculator can also evaluate any of the variables given the others are known.

Ohms To Farads Formula

The following formula is used to calculate the capacitance in Farads given the resistance in Ohms and the frequency in Hertz.

C = 1 / (2 * π * f * R)


  • C is the capacitance in Farads (F)
  • R is the resistance in Ohms (Ω)
  • f is the frequency in Hertz (Hz)
  • π is a constant, approximately equal to 3.14159

To calculate the capacitance, multiply the resistance by the frequency, then multiply the result by 2 and π. Finally, take the reciprocal of the result to get the capacitance in Farads.

What is Ohms To Farads?

Ohms and Farads are units of measurement used in electrical circuits, but they measure different things and cannot be directly converted. Ohms measure electrical resistance, which is the opposition to the flow of electric current. Farads, on the other hand, measure capacitance, which is the ability of a system to store an electric charge. Therefore, “Ohms to Farads” does not represent a conversion, but rather a relationship between resistance and capacitance in an electrical circuit.

How to Calculate Ohms To Farads?

The following steps outline how to calculate the Ohms To Farads using the formula: C = 1 / (2 * π * f * R).

  1. First, determine the resistance in Ohms (R).
  2. Next, determine the frequency in Hertz (f).
  3. Next, gather the formula from above: C = 1 / (2 * π * f * R).
  4. Finally, calculate the capacitance in Farads (C).
  5. After inserting the variables and calculating the result, check your answer with a calculator.
