About Frequency Converter
Frequency is a fundamental physical quantity representing the number of occurrences per unit time. In the International System of Units (SI), Hertz (Hz) is the standard, equal to one cycle per second. The Frequency Converter page converts your input to Hz (the base unit) and then recalculates every supported unit from that base.
Rotational speed (rpm) and angular frequency (rad/s) are conceptually different from frequency but mathematically relate to the same base—occurrences per second. Beats per Minute (BPM) is widely used in music and healthcare, with the same 1/60 Hz relationship as rpm.
The tool is practical for learning and quick reference, with explanatory notes when conversions are approximate rather than exact linear transformations.
