Megahertz to Revolutions per Minute 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 minute (rpm) is a unit of rotational frequency representing the number of complete rotations around a fixed axis in one minute. It's one of the most common units for measuring rotational speed in mechanical systems.

RPM became standard with the development of mechanical machinery during the Industrial Revolution. It provided an intuitive way to measure and specify rotational speeds for engines, motors, and machinery, becoming universally adopted in mechanical engineering.

RPM is extensively used in automotive engines, electric motors, machinery, and mechanical systems. It's standard for engine specifications, motor ratings, turntable speeds, and virtually all rotating mechanical equipment specifications.
