Microhertz (µHz)

Definition: One millionth (10⁻⁶) of a hertz — an SI-prefixed fraction of the base unit.

History: Formed by attaching the SI prefix "micro-" to hertz.

Current use: Used in helioseismology (studying oscillations of the Sun's surface, which repeat on the order of minutes) and other astrophysical contexts involving very long, very regular periodic signals.

Wavelength in Metres (m)

Definition: A wavelength of one metre expressed via its equivalent frequency, using f = c / λ — since λ = 1, the equivalent frequency is exactly the speed of light in metres per second.

History: The metre-wavelength unit sits at the center of this converter's wavelength scale, defined against the fixed, exact value of the speed of light (299,792,458 m/s) fixed by the SI's 1983 redefinition of the metre.

Current use: Falls in the FM radio and VHF television broadcast band (roughly 1-10 metre wavelengths).

About These Parameters

Value: The frequency or wavelength value you want to convert, expressed in the "From" unit. Accepts decimals, and can be a very large or very small number since this page spans everything from millihertz to exahertz.
From Unit: The unit your input value is currently measured in — pick a frequency unit (hertz, megahertz, gigahertz...) if you have a rate, or a wavelength unit (metres, nanometres...) if you have a physical wavelength.
To Unit: The unit you want the result converted into — can be a frequency unit, a wavelength unit, or the same category as From. Use the swap button to flip From and To instantly.

How Frequency Wavelength Conversion Works

The Formula

Two frequency units convert the normal way — multiply by the ratio of their factors. Converting between a frequency and a wavelength (or between two wavelength units) instead uses the physics relationship between them:

frequency (Hz) = speed of light (c) ÷ wavelength (m)
wavelength (m) = speed of light (c) ÷ frequency (Hz)

For Microhertz → Wavelength in Metres: 1 µHz = 2.99792E+14 m, computed via each unit's fixed relationship to hertz and, where wavelength is involved, the exact speed of light (299,792,458 m/s).

Why This Converter Is Different: Inverse, Not Multiplicative

Every other converter on this site works by multiplying a value by a fixed ratio — 1 foot is always 0.3048 metres, no matter what the input value is. Frequency and wavelength don't work that way: doubling a wavelength HALVES its frequency, and doubling a frequency HALVES its wavelength, because f and λ are reciprocally related through f = c / λ rather than being simple multiples of each other. This converter still fits the site's shared table/chart machinery — it just uses the reciprocal formula internally whenever a wavelength unit is involved, the same technique the Fuel Consumption Converter uses for its "volume per distance" units (L/100km, gal/mile), which are also reciprocals of the more common "distance per volume" units.

The Electromagnetic Spectrum, by Wavelength

Different wavelength ranges correspond to familiar names: radio waves span from kilometres down to about a millimetre, microwaves run from roughly a millimetre to 30 centimetres, infrared (heat) radiation runs from about a micrometre to a millimetre, visible light sits in a narrow band from about 380 to 750 nanometres, and ultraviolet and X-rays lie below that, down into the picometre range covered by the terahertz-and-above frequency units on this page.

Example

1 µHz equals 2.99792E+14 m. For scale, a typical FM radio station broadcasts around 100 MHz (a wavelength of about 3 metres), household WiFi runs at 2.4 or 5 GHz (wavelengths of about 12.5 cm or 6 cm), and visible green light has a wavelength around 530 nanometres, equivalent to roughly 566 THz.

Frequently Asked Questions

How many Wavelengths in Metres are in 1 Microhertz?

1 Microhertz (µHz) equals exactly 2.99792E+14 Wavelengths in Metres (m).

Why isn't this a simple multiply-by-a-factor conversion like other unit converters?

Because frequency and wavelength are reciprocally related (f = c / λ), not proportionally related. A longer wavelength always means a lower frequency, so converting between them requires dividing the speed of light by the value rather than multiplying by a fixed ratio.

What speed of light does this converter use?

The exact SI-defined value, 299,792,458 metres per second — the speed of light in a vacuum, which has been an exactly fixed constant (not a measured approximation) since the metre itself was redefined against it in 1983.

What are the Compton wavelengths doing on a frequency-wavelength converter?

The Compton wavelength of a particle (electron, proton, or neutron) is a fixed physical constant with units of length, so it converts to an equivalent frequency through the exact same f = c / λ relationship as any other wavelength — it's included as a fixed reference point useful in particle and nuclear physics calculations.

Does this work for sound waves too?

No — the f = c / λ relationship here uses the speed of light, which only applies to electromagnetic waves (radio, light, X-rays, etc). Sound waves travel at the much slower speed of sound (about 343 m/s in air), so sound frequency-to-wavelength conversion needs a different constant and isn't covered by this tool.
