Millihertz to Revolutions per Second Converter

A millihertz (mHz) is a unit of frequency equal to one thousandth of a hertz (0.001 Hz). It represents very low frequencies found in extremely slow oscillations, geological processes, and some biological rhythms.

The millihertz became necessary for describing extremely slow periodic phenomena in scientific research. It was particularly important in geophysics, astronomy, and biological studies where natural cycles occur over very long time periods.

Millihertz is used in geophysics for seismic wave analysis, astronomy for stellar oscillations, biological research for circadian rhythms, and precision timing applications. It's essential for measuring very slow natural cycles and long-period oscillations.

Revolutions per second (rps) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one second. It provides a more direct relationship to the hertz unit for rotational measurements.

RPS developed as a scientific alternative to RPM, providing a direct conversion to hertz (1 rps = 1 Hz for rotational motion). It became important in scientific and engineering applications where SI units were preferred over traditional mechanical units.

RPS is used in scientific applications, high-speed machinery, precision instruments, and engineering calculations where direct conversion to hertz is beneficial. It's found in centrifuge specifications, high-speed motor ratings, and scientific equipment.
