Revolutions per Hour to Gigahertz Converter

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.

A gigahertz (GHz) is a unit of frequency equal to one billion hertz (10⁹ Hz). It represents very high frequencies commonly found in microwave radiation, computer processors, and modern wireless communications.

The gigahertz became prominent with the development of microwave technology and high-speed electronics in the mid-20th century. It gained widespread recognition with computer processor speeds and became a household term with the advancement of personal computers and wireless technology.

Gigahertz is extensively used in computer processor specifications, wireless communications (WiFi, Bluetooth, cellular), microwave technology, and radar systems. It's standard for CPU clock speeds, wireless frequency bands, and microwave oven operating frequencies.
