Frequency Converter

Frequency Converter — Convert Hz, kHz, MHz, GHz Online

The Frequency Converter is a free online tool that converts between every common frequency unit: Hertz, kilohertz, megahertz, gigahertz, terahertz, BPM (beats per minute), RPM (revolutions per minute), radians per second, and degrees per second. Whether you are working with radio frequencies, audio sampling rates, processor clock speeds, mechanical rotation, or musical tempo, this converter gives you exact answers in seconds.

Where Frequency Conversion Matters

Frequency appears across countless fields. Audio engineers convert sample rates (44.1 kHz CD audio, 48 kHz video, 96 kHz studio). Radio operators tune across MHz and GHz. Computer architects benchmark processors in GHz. Mechanical engineers convert RPM to rad/s for torque calculations. Musicians convert BPM to milliseconds per beat for delay timing. Every domain uses its own preferred unit, and converting accurately between them prevents errors that could waste hours of debugging or cause expensive equipment damage.

How to Use the Converter

Enter your frequency value, pick the source unit, and choose the target unit. The conversion appears instantly with high precision (down to femtoseconds-equivalent if needed). The tool handles scientific notation for very low or very high frequencies, and supports both linear (Hz) and angular (rad/s) frequency systems with correct conversion factors.

Common Use Cases

Audio producers calibrate sample rates. Radio engineers tune transmitters. Mechanical engineers analyze rotating machinery. Game developers sync music to frame rates. Physics students complete oscillation homework. The tool is free, runs entirely in your browser, mobile-friendly, and requires no signup.
