Frequency Calculator
Calculate frequency from a period or from the number of cycles completed over a measured time interval.
Enter frequency details
Result
Enter the cycle count and time, or the period of one cycle, then calculate the frequency.
What frequency means
Frequency tells you how many complete cycles occur each second. Higher frequency means the repeating event happens more often.
Frequency and period
Frequency and period are reciprocals. A shorter period produces a higher frequency, while a longer period produces a lower frequency.
Common frequency uses
Frequency is used for sound, radio signals, alternating current, rotating machinery, vibrations, and many repeating processes.
Frequently asked questions
What formula does this calculator use?
For multiple cycles, frequency = number of cycles ÷ elapsed time. From a period, frequency = 1 ÷ period.
What is one hertz?
One hertz means one complete cycle every second.
How are frequency and period related?
They are reciprocals. Frequency equals 1 divided by period, and period equals 1 divided by frequency.
What is angular frequency?
Angular frequency measures the rate of oscillation in radians per second and is calculated as 2π times ordinary frequency.
