About Hertz (Hz)
The SI unit of frequency equal to one cycle per second (1 Hz = 1 s⁻¹). Named after Heinrich Hertz, who first demonstrated electromagnetic waves in the 1880s. Hertz is the universal unit for any periodic phenomenon: display refresh rates (60 Hz, 120 Hz, 144 Hz), mains power (50 or 60 Hz), heart rate (~1 Hz at rest), sound wave pitch (human hearing: 20 Hz to 20 kHz), and vibration analysis of rotating machinery.
About Gigahertz (GHz)
A frequency unit equal to 1,000,000,000 Hz. Gigahertz is the standard unit for modern CPU clock speeds (3–5 GHz), Wi-Fi (2.4, 5, 6 GHz), cellular radio (5G mmWave up to 40 GHz), radar, GPS carrier frequencies (~1.5 GHz), and microwave ovens (2.45 GHz). Semiconductor datasheets, RF network-analyzer traces, and consumer wireless-device spec sheets all use GHz as the default frequency unit.

Frequently Asked Questions
How do I convert Hertz to Gigahertz?
The SI unit of frequency equal to one cycle per second (1 Hz = 1 s⁻¹). To convert Hertz to Gigahertz, multiply by 1.0000e-9. For example, 25 Hz equals 2.500000e-8 GHz.
How many Gigahertz are in 1 Hertz?
There are 1.000000e-9 Gigahertz in 1 Hertz.
How many Hertz are in 1 Gigahertz?
There are 1.000000e+9 Hertz in 1 Gigahertz.
What is the formula for Hertz to Gigahertz conversion?
The formula is: multiply by 1.0000e-9. This means 1 Hz = 1.000000e-9 GHz.
Is a Hertz bigger than a Gigahertz?
Yes. One Hertz is larger than one Gigahertz because 1 Hz equals 1.000000e-9 GHz, which is less than 1.
