Frequency Period Converter

Convert frequency (Hz) to period (seconds) or period to frequency using simple physics formulas.

Frequency is cycles per second (Hz).

How frequency and period are related

Frequency is the number of cycles per second (Hz). Period is the time for one cycle (s).

They are inverses: T = 1 / f and f = 1 / T.

Use consistent units (Hz and seconds) to keep the results in standard SI units.
