Online calculators and formulas for calculating the frequency and period of AC voltages
On this page you can calculate the duration of the period for a certain frequency, or the frequency for a period.

Tip: A calculator for calculating frequency and wavelengths can be found here
The frequency is the number of periods per second. The formula below applies to the calculation of the frequency:
\(\displaystyle f= \frac{1}{T}\)
The duration of a period is calculated using the following formula:
\(\displaystyle T= \frac{1}{f}\)
\(\displaystyle f\)
Frequency in Hz
\(\displaystyle T\)
Duration of a period in seconds
