What is Frequency Converter?

Frequency Converter is a free online tool that converts between different units of frequency and rotational speed. It supports standard frequency units (Hz, kHz, MHz, GHz, THz), rotational units (RPM, RPS), and angular frequency units. Perfect for electronics, engineering, physics calculations, and audio applications.

Frequently Asked Questions

How accurate are the conversions?

All conversions use standard conversion factors and are accurate to 6 decimal places. For most practical purposes, this provides excellent precision.

What's the difference between Hz and RPM?

Hz measures cycles per second, while RPM measures revolutions per minute. 1 Hz = 60 RPM for rotational motion.

Is my data secure?

Yes, all calculations happen locally in your browser. Your data never leaves your device.

Can I use this offline?

Yes, once loaded, the converter works completely offline in your browser.
