The following list illustrates various frequencies, measured in hertz, according to decade in the order of their magnitudes, with the negative decades illustrated by events and positive decades by acoustic or electromagnetic uses. Acoustic – frequency of G −7, the lowest note sung by the singer with the deepest voice in the world, Tim Storms.

The femtohertz is a multiple of the unit hertz (Hz) for frequency. The International System of Units (SI) defines the prefix femto (f) as a factor of 10⁻¹⁵ or 0.000000000000001. Per this definition, one femtohertz is 10⁻¹⁵ hertz. The femtohertz is represented by the symbol fHz. A table of various frequencies derived from SI multiples:

The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), often described as being equivalent to one event (or cycle) per second. [1][a] The hertz is an SI derived unit whose formal expression in terms of SI base units is s −1, meaning that one hertz is one per second or the reciprocal of one second. [2] .

Definition of FHZ in Military and Government. What does FHZ stand for?

Frequency is used to measure physical actions that are cyclic in nature, that follow a pattern which repeats many times such as oscillations and rotational movement. Frequency is typically defined as the number of cycle completed in a unit period of time, where the SI unit for frequency which is the Hertz equals 1 cycle per second.

A femtohertz (fHz) is a SI-multiple (see prefix femto) of the frequency unit hertz and equal to 1.0 × 10 -15 hertz.

FHZ can refer to: Femtohertz, an SI unit for frequency equivalent to one quintillionth of a hertz; Fakahina Airfield, an airfield in Fakahina atoll, French Polynesia, by IATA code, the fraction of stars with rocky planets in the habitable zone, in Seager's variant of the Drake equation; see Drake equation#Modifications

Femtohertz (fHz) is a unit of frequency equal to 1/1 000 000 000 000 000 or 1.0E-15 hertz. This unit is a mixture of metric prefix femto (f) and the SI derived unit of frequency hertz (Hz). Plural name is femtohertzs.
