Frequency converters
Frequency counts repetitions per unit time — cycles of a wave, revolutions of a shaft, oscillations of a clock. The SI unit is the hertz, defined by the SI Brochure as one cycle per second, and named for Heinrich Hertz. Rotational-speed units like RPM (revolutions per minute) and radians per second describe the same underlying quantity from a mechanical-engineering angle.

Frequency units in terms of the hertz
Every frequency unit on Convertitive is defined as an exact ratio of the hertz (Hz), the reference unit for this category. The table below shows what one of each unit equals in hertz — the constant every converter on this page is built from.
| Unit | Symbol | 1 unit in hertz |
|---|---|---|
| Hertz | Hz | base unit |
| Kilohertz | kHz | 1000 Hz |
| Megahertz | MHz | 1000000 Hz |
| Gigahertz | GHz | 1000000000 Hz |
| Revolutions per minute | rpm | 0.0166667 Hz |
| Radians per second | rad/s | 0.159155 Hz |
To convert between any two units, Convertitive scales the input to hertz using these factors and then back out to the target unit — so every result on this page traces to a single, exact definition rather than a chained approximation. Pick any pair above to see the formula, a 50-row reference table, and worked examples.
