Convert between Hz, kHz, MHz, and GHz. 1 kHz = 1,000 Hz, 1 MHz = 1,000,000 Hz, 1 GHz = 1,000,000,000 Hz. WiFi uses 2.4 GHz or 5 GHz. FM radio: 88-108 MHz. AM radio: 530-1700 kHz. CPU speed measured in GHz. Human hearing: 20 Hz to 20,000 Hz.

🤔 How Does This Work?
Frequency conversion uses powers of 10:
1 kHz = 1,000 Hz (10³)
1 MHz = 1,000,000 Hz (10⁶)
1 GHz = 1,000,000,000 Hz (10⁹)
1 THz = 1,000,000,000,000 Hz (10¹²)
❓ Frequently Asked Questions
What is frequency?▼
Frequency is the number of cycles or oscillations per second, measured in Hertz (Hz). 1 Hz = 1 cycle per second. Higher frequency = more cycles per second = shorter wavelength (if dealing with waves). Used to describe sound pitch, radio waves, electrical current (50/60 Hz), processor speed (GHz), and light (THz).
What is the difference between 2.4 GHz and 5 GHz WiFi?▼
2.4 GHz: longer range, better at penetrating walls and floors, more congested (shared with microwaves, Bluetooth), slower top speeds. 5 GHz: shorter range, better speed in close proximity, less interference. Choose 2.4 GHz for distant rooms or through walls. Choose 5 GHz for close proximity and best speeds.
