About Frequency Conversions
Frequency measurements quantify how often a periodic event occurs per unit of time. The hertz (Hz), defined as one cycle per second, is the SI unit of frequency and the foundation for all derived frequency units. In electronics, kilohertz (kHz) describes AM radio frequencies, megahertz (MHz) covers FM radio and older processors, gigahertz (GHz) measures modern CPU clock speeds and Wi-Fi bands, and terahertz (THz) enters the realm of spectroscopy and imaging. Revolutions per minute (RPM) bridges frequency and mechanical engineering — a car engine idling at 800 RPM operates at about 13.33 Hz. Our converter uses exact SI prefix relationships for precision across all scales.
| Unit Name | Symbol | Value | Formula |
|---|---|---|---|
| Gigahertz | GHz | 1 × 10⁻⁹ | multiply by 1,000,000,000 |
| Hertz | Hz | 1 | base unit |
| Kilohertz | kHz | 0.001 | multiply by 1,000 |
| Megahertz | MHz | 0.000001 | multiply by 1,000,000 |
| Revolutions per Minute | RPM | 60 | divide by 60 |
| Terahertz | THz | 1 × 10⁻¹² | multiply by 1,000,000,000,000 |
