Frequency Converter — Hz, kHz, MHz, GHz & RPM

Easiest Converter’s frequency converter gives fast, precise conversions for electronics, RF work, audio engineering, machinery, and rotational systems. Convert between hertz (Hz), kilohertz (kHz), megahertz (MHz), gigahertz (GHz), and revolutions per minute (RPM) with clean, copy-ready results.

Internally, calculations reference hertz for consistent math across linear and rotational measures. Popular pairs include Hz ⇄ kHz/MHz/GHz for signal work and Hz ⇄ RPM for motors, spindles, and mechanical systems.

Why this frequency converter? The UI is tuned for clarity—keyboard-friendly inputs, a one-tap swap, and a copy-to-clipboard result string. Values use sensible precision so numbers stay readable while remaining accurate for lab notes, specs, and reports.

Supported units: Hz, kHz, MHz, GHz, and RPM. Whether you’re working on oscillators, filters, or drive systems, this converter keeps your frequency math quick, consistent, and easy to share.

• Use ⇄ to swap “From” and “To.”
• Click 📋 to copy a tidy result string.
• 1 Hz = 60 RPM ÷ (2π) for angular frequency; RPM gives practical rotational speed.
