hertz to ghz | Exact Decimal + Formula
1 Hertz = 1.0000e-9 Gigahertz
One gigahertz equals exactly a billion hertz. Real-world use: audio frequencies, processor clock rates, and AC power mains (50/60 hz). This page expresses those values in gigahertz, which is used for modern processor speeds, wi-fi bands (2.4/5/6 ghz), and radar. Because the difference in scale is so large, real-world figures usually pass through an intermediate unit first; the table below makes direct conversion easy to check. Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.
About Hertz and Gigahertz
Hertz (Hz)
The hertz measures cycles per second.
Where it's used: Audio frequencies, processor clock rates, and AC power mains (50/60 Hz).
Gigahertz (GHz)
A gigahertz is 1,000,000,000 hertz.
Where it's used: Modern processor speeds, Wi-Fi bands (2.4/5/6 GHz), and radar.

Hz to GHz Formula and Examples
Direct Formula
GHz = Hz × 1.000000e-9 Inverse Formula
Hz = GHz × 1000000000 Mental Math Shortcut
Divide the value by roughly 1000000000 to quickly estimate the converted result.
Common Hertz to Gigahertz Calculations
- 5 Hz = 5.0000e-9 GHz
- 10 Hz = 1.0000e-8 GHz
- 50 Hz = 5.0000e-8 GHz
- 100 Hz = 1.0000e-7 GHz
- 500 Hz = 5.0000e-7 GHz
Precision & Practical Use
For example, 10 Hz = 1.0000e-8 GHz — roughly fractional unit measurement.
Results are computed to up to 9 decimal places. Round to the precision of your measuring instrument — for most frequency applications, 2–3 significant figures are plenty.

How to Convert Hertz to Gigahertz
How many gigahertzes are in one hertz?
One Hertz (Hz) equals 1.0000e-9 Gigahertz (GHz). To convert hertzes to gigahertzes, multiply the hertz value by 1.0000e-9.
How do I convert Hertz to Gigahertz?
Multiply your hertz value by 1.0000e-9 to get the result in Gigahertz: GHz = Hz × 1.0000e-9. For example, 5 Hz = 5.0000e-9 GHz.
What is the formula for converting Hz to GHz?
The conversion formula is GHz = Hz × 1.0000e-9. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for Hz to GHz?
Divide the value by roughly 1000000000 to quickly estimate the converted result.
