Megahertz to Revolutions per Hour Converter

A megahertz (MHz) is a unit of frequency equal to one million hertz (10⁶ Hz). It represents high frequencies commonly used in radio communications, early computer systems, and various electronic applications.

The megahertz became important with the development of radio technology in the early 20th century. It was essential for describing radio frequency bands and became widely known through radio broadcasting, later extending to early computer systems and electronic devices.

Megahertz is widely used in radio broadcasting (AM/FM radio), early computer specifications, electronic circuits, and various communication systems. It's standard for radio frequency allocations, older processor speeds, and many electronic device specifications.

Revolutions per hour (rph) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one hour. It's used for very slow rotational systems and astronomical observations.

RPH became useful for describing very slow rotational systems such as astronomical observations, large industrial equipment, and systems where rotational speeds are extremely low. It provided appropriate scaling for applications where RPM would result in very small decimal numbers.

RPH is used for astronomical observations (planetary rotation), very slow industrial processes, large rotating equipment, and systems with extremely low rotational speeds. It's found in astronomical calculations and specifications for very slow rotating machinery.
