Frequency Converter - Convert Between Hz, kHz, MHz, GHz Online Free
Convert between hertz, kilohertz, megahertz, gigahertz, and terahertz.
What Is a Frequency Converter?
A frequency converter converts between different frequency measurement units.
Supported Units
- Hertz (Hz) — SI unit. 1 cycle per second.
- Kilohertz (kHz) — 1000 Hz. Audio range.
- Megahertz (MHz) — 1,000,000 Hz. Radio frequencies.
- Gigahertz (GHz) — 1,000,000,000 Hz. CPU/wifi.
- Terahertz (THz) — 10^12 Hz. Advanced research.
How Does Frequency Converter Work?
1 kHz = 1000 Hz, 1 MHz = 1,000,000 Hz, 1 GHz = 1,000,000,000 Hz, 1 THz = 10^12 Hz.
How to Use This Tool
