Calculate Capacitive reactance: 1uF, 50Hz, kΩ
This calculation can calculate the capacitive reactance XC of a capacitor knowing its capacitance and the frequency. You can also calculate the capacitance knowing the desired reactance and frequency, or calculate the frequency knowing the capacitive reactance and capacitance. XC = 1 / (2πfC)
Enter any 2 values, the 3rd one will be calculated:

Capacitive reactance formula says:
•The capacitive reactance (Xc) of a 1uF (one microfarad) capacitor at 50Hz (fifty hertz) is 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms).•For a 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms) capacitive reactance at 50Hz (fifty hertz), you need a 1uF (one microfarad) capacitor.
•A 1uF (one microfarad) capacitor would have a 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms) reactance at 50Hz (fifty hertz) frequency.
