Introducing the Frequency Converter — Hz, kHz, MHz, GHz, RPM & rad/s

Frequency is measured in wildly different units depending on the field — gigahertz for a CPU, RPM for a motor, rad/s for an oscillation. The new Frequency Converter brings them together so you can convert between any of them in one step.

What it does

• 7 units: Hz, kHz, MHz, GHz, THz, RPM, and rad/s.
• Live conversion: type a value, pick your units, and the answer updates instantly — no Calculate button.
• Quick-convert chips: one-tap presets for Hz→kHz, MHz→GHz, RPM→Hz, and more.
• Full reference table: see your value expressed in every unit at once.
• Client-side: fixed constants, no network — nothing is uploaded.

Why it matters

The SI prefixes are clean thousands, but RPM brings a 60 and rad/s brings a 2π. Chaining those awkward factors by hand is where mistakes creep in. Letting the tool normalise everything through the hertz keeps the decimals exact across the whole spectrum.
