Hertz to GHz formula and what each symbol means
GHz = Hz × 1×10⁻⁹
| Symbol | Meaning |
|---|---|
| Hz | Hertz |
| GHz | Gigahertz |
Hertz to GHz examples
1 Hz
1 Hz × 1×10⁻⁹ = 1×10⁻⁹ GHz.
10 Hz
10 Hz × 1×10⁻⁹ = 1×10⁻⁸ GHz.
100 Hz
100 Hz × 1×10⁻⁹ = 1×10⁻⁷ GHz.
Hertz compared with GHz
One GHz is 1,000,000,000 times as large as one Hz, so your number gets smaller when you convert hertz to GHz and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About hertz and GHz
Hertz (Hz): The SI unit of frequency, one cycle per second. Gigahertz (GHz): One billion hertz.
Where hertz to GHz conversions are used
Radio, Wi-Fi and processors are described in MHz and GHz. Engines, motors and turbines are rated in revolutions per minute (rpm).
How to calculate Hertz to GHz step by step
- Enter the value in Hz (the starting unit).
- Multiply by 1×10⁻⁹, because 1 Hz = 1×10⁻⁹ GHz.
- The product is the value in GHz. To go back, divide by 1×10⁻⁹ or multiply by 1,000,000,000.

Common mistakes when calculating Hertz to GHz
- Confusing hertz (cycles per second) with radians per second: ω = 2πf.
- Dividing when you should multiply: from Hz to GHz multiply by 1×10⁻⁹; from GHz to Hz divide by 1×10⁻⁹.
Hertz to GHz FAQ
How many GHz are in 1 Hz?
1 Hz equals 1×10⁻⁹ GHz.
How many Hz are in 1 GHz?
1 GHz equals 1,000,000,000 Hz.
Is 1 Hz = 1×10⁻⁹ GHz an exact conversion?
The factor is shown rounded to 7 significant figures (1×10⁻⁹). The calculator above uses more digits.
What is a gigahertz (GHz)?
One billion hertz.
How can I estimate hertz to GHz in my head?
One GHz is 1,000,000,000 times as large as one Hz, so your number gets smaller when you convert hertz to GHz and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
What is 7 Hz in GHz?
7 Hz = 7×10⁻⁹ GHz (since 7 × 1×10⁻⁹).
What is 40 Hz in GHz?
40 Hz = 4×10⁻⁸ GHz (since 40 × 1×10⁻⁹).
What is 200 Hz in GHz?
200 Hz = 2×10⁻⁷ GHz (since 200 × 1×10⁻⁹).
How many decimals should I keep when converting Hz to GHz?
Match the precision of your original measurement. For example, 1×10⁻⁸ GHz rounds to 1×10⁻⁸ GHz at 3 significant figures; keep more digits only for engineering or scientific work.
