To convert from gigahertz (GHz) to millihertz (mHz), use the following formula:
Let's convert 5 gigahertz (GHz) to millihertz (mHz).
Using the formula:
Therefore, 5 gigahertz (GHz) is equal to millihertz (mHz).

A gigahertz (GHz) is a unit of frequency in the International System of Units (SI), equal to one billion hertz (109 Hz). The plural form is gigahertz.
The gigahertz measurement is famously used to indicate a computer's CPU clock speed, which tells you how many processing cycles it can complete per second.
For example, a 3.2 GHz processor can handle 3.2 billion cycles every second.
While a higher GHz number often suggests a faster processor, overall performance also depends on other critical factors, such as the number of cores and the chip's architecture.
Your daily wireless connections, like Wi-Fi and Bluetooth, operate on specific gigahertz frequency bands.
The most common Wi-Fi bands are 2.4 GHz and 5 GHz.
Each has its own strengths:
Similarly, 5G mobile networks use various GHz frequencies to deliver the ultra-fast data transmission that powers modern mobile devices.
Focusing solely on gigahertz to judge a processor's performance is a common mistake known as the "gigahertz myth."
A processor with a lower clock speed but a more efficient design (e.g., more cores, a larger cache, or better instructions per cycle) can easily outperform a processor with a higher GHz rating.
This is why comparing processors requires looking at a combination of specifications, not just the clock speed.
Ever wondered how scientists measure incredibly slow, barely-there movements, like the subtle shifting of continents or the rhythm of a distant star?
They often use a special unit of frequency called the millihertz (mHz).
A millihertz is a unit of frequency equal to one-thousandth of a hertz (0.001 Hz). It's designed to measure things that happen very, very slowly.
While a standard hertz (Hz) measures cycles per second (think sound waves or computer speeds), a millihertz measures events that occur very slowly, taking a very long time to complete a single cycle.
To put it in perspective, something oscillating at one mHz takes 1,000 seconds—or nearly 17 minutes—to complete just one cycle!
This makes the unit perfect for tracking extremely slow phenomena.
Key applications include:
Frequency and time are two sides of the same coin.
In physics, the time it takes for one complete cycle is called the period (T), while frequency (f) refers to the number of cycles that occur per second. They are inversely related: as one increases, the other decreases.
The relationship is expressed as T = 1/f.
To find the period in seconds from a frequency in mHz, you first convert mHz to Hz (1 mHz = 0.001 Hz) and then find its reciprocal.
Formula:
Example:
The mHz range is crucial for one of the most exciting fields in modern astronomy: the search for gravitational waves.
Space-based observatories, such as the Laser Interferometer Space Antenna (LISA), are specifically designed to detect low-frequency gravitational waves in the millihertz band.
These ripples in spacetime are believed to be caused by some of the most massive and dramatic events in the universe, such as:
Detecting signals in the millihertz band offers scientists a unique opportunity to explore cosmic events, allowing them to observe the universe in a completely new way.
