Kilohertz to Revolutions per Hour 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 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.
