Millihertz to Cycles 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.

Cycles per second (cps) is a unit of frequency representing the number of complete cycles of a periodic phenomenon occurring in one second. It's essentially equivalent to hertz but predates the modern SI terminology.

Cycles per second was the original term used to describe frequency before the adoption of the hertz in 1960. It was widely used in early electronics, radio, and physics literature, providing a descriptive term for periodic phenomena.

Cycles per second is rarely used in modern applications, having been replaced by hertz in scientific and technical contexts. It may still appear in historical literature, educational materials, or informal descriptions of frequency.
