What is Hertz Equal To and How to Convert Hz to Seconds

In physics and electrical engineering, understanding what hertz is equal to is fundamental: 1 Hertz equals exactly 1 complete periodic oscillation per second ($1\text{ s}^{-1}$). When engineers need to convert hz to seconds or turn hertz into seconds, the relationship is an exact inverse:

Time Period: T = 1 / f  |  Frequency: f = 1 / T (sec to hz conversion)

Convert from Hz to Rad/s (Angular Velocity)

To convert from hz to rad s, multiply the linear frequency by $2\pi$ radians (one full rotation on a circle):

ω = 2 × π × f

Crucial for alternating current (AC) circuit analysis and mechanical motors.

Sec to Hz Conversion Formula

For sec to hz conversion, divide 1 by the period in seconds:

Frequency (Hz) = 1 / Time (s)

E.g., an oscillation completing in 0.005 seconds has a frequency of 1 / 0.005 = 200 Hz.
