Frequency Unit Converter

Cyclic frequency measures how many complete cycles occur per second (hertz). Angular rates such as radians per second or revolutions per minute relate to hertz through standard factors. This tool converts between common engineering and physics units in one step.

Supported units

You can convert between hertz, millihertz, kilohertz, megahertz, gigahertz, terahertz, revolutions per second, RPM, degrees per second, radians per second, and related minute or hour variants. Results include the equivalent value in hertz for cross-checking.

Accuracy notes

Calculations use double-precision floating point values. Display uses significant digits appropriate for quick checks rather than metrology-grade rounding rules.

Frequently Asked Questions

How is RPM converted?

Revolutions per minute are treated as cycles per minute, so hertz equals RPM divided by sixty.

How are radians per second handled?

Angular frequency ω in rad/s maps to cyclic frequency f in Hz with f = ω / (2π).

Can I convert audio sample rate kHz to MHz?

Yes. Pick kilohertz as the source unit and megahertz as the target, then enter your numeric value.

Is data sent to a backend?

No. All math runs locally in the browser.
