Kilohertz to Revolutions per Minute Converter

A kilohertz (kHz) is a unit of frequency equal to one thousand hertz (10³ Hz). It represents moderate frequencies commonly found in audio applications, low-frequency radio, and various electronic systems.

The kilohertz became important with the development of audio technology and early radio communications. It provided a convenient scale for describing audio frequencies and low-frequency radio waves, becoming essential in the development of broadcasting and audio equipment.

Kilohertz is extensively used in audio engineering, AM radio broadcasting, audio equipment specifications, and low-frequency electronic applications. It's standard for describing audio frequency ranges, AM radio frequencies, and various audio processing equipment.

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.
