How many kHz are in 1 GHz?

There are exactly 1,000,000 kilohertz (kHz) in one gigahertz (GHz). The prefix "kilo" means 1,000 and "giga" means 1,000,000,000, so 1 GHz = 1,000,000 kHz.

What is 2.4 GHz in kHz?

2.4 GHz equals 2,400,000 kHz. This is the center of the 2.4 GHz WiFi band used in 802.11b/g/n wireless networking and Bluetooth.

What is 5 GHz in kHz?

5 GHz equals 5,000,000 kHz. This is the 5 GHz WiFi band used in 802.11a/n/ac/ax networking for higher throughput and lower interference.

Is kHz bigger or smaller than GHz?

Kilohertz (kHz) is much smaller than gigahertz (GHz). One GHz is 1,000,000 times larger than one kHz. A signal at 1 GHz oscillates at a far higher frequency than one at 1 kHz.

What common frequencies are measured in GHz vs kHz?

WiFi (2.4 GHz / 5 GHz), Bluetooth (2.4 GHz), and cellular bands (0.7–3.5 GHz) are measured in GHz. AM radio (540–1700 kHz) and longwave radio (30–300 kHz) are measured in kHz.

Summary

Gigahertz (GHz) and kilohertz (kHz) are both units of frequency separated by six orders of magnitude. One gigahertz equals exactly 1,000,000 kilohertz, so to convert GHz to kHz you multiply by 1,000,000. This converter is useful when working with high-frequency bands like WiFi or cellular networks and need to express them in kilohertz for datasheets or lower-level signal analysis.

How it works

Type a frequency value in gigahertz (GHz) into the input field.
The equivalent in kilohertz (kHz) appears instantly below.
The formula used is: kHz = GHz × 1,000,000.
