Frequency & Period Calculator – Convert Seconds to Hz
Convert a period in seconds to frequency in hertz with f = 1/T using a positive period value.
Frequency and period are reciprocals. The calculator accepts a positive period in seconds and returns the corresponding frequency in hertz.
How it works
f = 1 / T, where T is period in seconds and f is frequency in hertz.
Example
A period of 0.02 seconds gives f = 1 / 0.02 = 50 Hz.
How to use
- Enter the period in seconds.
- Make sure the period is greater than zero.
- Calculate to convert the period to frequency.
- Read the result in hertz (Hz).
Key features
- Reciprocal frequency calculation
- Seconds-to-hertz workflow
- Positive-value validation
- Browser calculation
Common uses
- Wave and oscillation problems
- Electronics timing checks
- Converting period measurements to frequency
Frequently asked questions
Can the period be zero?
No. Frequency would be undefined because the formula divides by the period.
How do I convert frequency back to period?
Use the reciprocal relationship T = 1/f.
