Frequency Converter

Convert between frequency units used in electronics, radio, audio, and computing. 1 Hz = 1 cycle per second.

1 GHz = 1000 MHz = 1,000,000 kHz = 1,000,000,000 Hz

AM radio: 530-1700 kHz. FM radio: 88-108 MHz. WiFi: 2.4 & 5 GHz. CPU: 3-5 GHz.

What frequencies does WiFi use?

2.4 GHz (longer range, more interference) and 5 GHz (faster, shorter range). WiFi 6E adds 6 GHz.

How does frequency relate to wavelength?

Wavelength = Speed of Light / Frequency. Higher frequency = shorter wavelength. FM radio (100 MHz) ≈ 3 meter wavelength.
