Understanding frequency units
Frequency measures how many cycles per second a wave completes, with the base unit being the Hertz (Hz). Everyday signals span many orders of magnitude: FM radio broadcasts between 87.5 and 108 MHz, Wi-Fi operates at 2.4 GHz and 5 GHz, modern CPU clocks run at 3–5 GHz, and visible light oscillates at 400–700 THz. Each unit is a power of 1,000 above Hz: 1 kHz = 10³ Hz, 1 MHz = 10⁶ Hz, 1 GHz = 10⁹ Hz, 1 THz = 10¹² Hz. All conversions run entirely in your browser.
