Calculate Frequency

Frequency is the reciprocal of period when T is measured in seconds, giving frequency in hertz.

Formula: f = 1 ÷ T

Keep physical units consistent before applying the relationship. If the tool uses an assumed model, changing the model or a measured input can change the result even when the arithmetic is correct.

Check the units first, then substitute the same values into the displayed physical relationship to confirm the result.
