Privacy First: Your files are processed securely. Whenever possible, processing happens in your browser and files are never stored on our servers.

Convert frequency across 13 units: SI (μHz, mHz, Hz, kHz, MHz, GHz, THz) and Mechanical/Angular (rps, rpm, rph, rad/s, °/s, cycles/min). Key: 1 Hz = 60 rpm = 2π rad/s. Quick-reference covers Wi-Fi (2.4/5 GHz), FM radio (87.5–108 MHz), mains power (50/60 Hz), and human hearing (20 Hz–20 kHz). 100% browser-based.
