Hertz (Hz) measures frequency, or cycles per second. Want to know how long one cycle lasts if you know the frequency in Hz? It’s a simple math problem to convert sec to Hz and back again.
How to convert hertz to seconds
Converting hertz (Hz) to seconds is pretty straightforward, once you know the formula.
The formula for conversion
The formula is:
Seconds = 1 / Frequency (Hz)
This calculation tells you the time duration, in seconds, of one complete cycle of a repeating event.
Practical application
For example, if you have a frequency of 2 Hz, then the time period is 1 / 2 = 0.5 seconds.
This conversion is used in electronics, audio engineering, physics, and many other scientific fields.
Cycle/Second and Hertz Equivalence
The term “cycle/second” is just another way to talk about frequency.
One cycle/second is equal to 1 Hz. That means that Hertz and cycle/second are interchangeable. For example, 10 cycles/second is the same as 10 Hz.
Converting from cycles/second to Hertz is incredibly easy because the numerical value never changes. Only the label changes.
Key Takeaways
Hertz (Hz) and seconds are inversely proportional. So, if you want to convert from seconds to Hz, you’ll use the formula: Seconds = 1 / Frequency (Hz).
Knowing how to convert from one unit to the other is important in a wide range of technical and scientific fields.
