Gigahertz to Revolutions per Second Converter

The gigahertz (GHz) equals one billion hertz, the standard unit for modern CPU clock speeds, Wi-Fi frequencies, and 5G cellular bands. A typical laptop processor runs at 2–5 GHz, while Wi-Fi operates at 2.4 GHz or 5 GHz. One gigahertz equals 1,000 megahertz or one billion cycles per second.

Revolutions per second (rps) measures rotational speed as complete turns per second, equivalent to exactly one hertz. While less common than rpm in everyday specifications, rps is used in physics, engineering analysis, and some industrial equipment ratings. One rps equals exactly 60 rpm.
