Unit nHz
Name nanohertz
Category Frequency
Details A nanohertz (nHz) is a unit of frequency in the International System of Units (SI), representing one billionth of a hertz. Frequency is a measure of the number of occurrences of a repeating event per unit of time. In terms of waves or oscillations, it refers to how many cycles are completed in one second.

The hertz (Hz) is the SI unit for frequency, and one hertz represents one cycle per second. The nanohertz (nHz) is a derived unit, where one nanohertz equals 10^-9 hertz or 0.000000001 Hz.

In the field of frequency, nanohertz has applications in areas where extremely low frequencies or long-period events are studied. For example, in astronomy, the observation of long-period gravitational waves or oscillations in celestial bodies may be measured in nanohertz.
