What Does Gigahertz (GHz) Mean?
Gigahertz (GHz) is a frequency unit that measures the number of cycles per second. Hertz (Hz) refers to the number of cycles per second with periodic 1-second intervals. One megahertz (MHz) equals 1,000,000 Hz. One gigahertz is equal to 1,000 megahertz (MHz) or 1,000,000,000 Hz.
Techopedia Explains Gigahertz (GHz)
One gigahertz equals 1,000,000,000 Hz or 1,000 MHz and has a frequency measurement with periodic 1-second cycles. A nanosecond is one-billionth of a second or one-thousandth of a microsecond. A nanosecond’s numeric order is 10 or 0.000000001. Hertz is based on total rotations per second, that is, one full second rotation equals 1 Hz. One kilohertz represents 1,000 rotations per second. One megahertz represents 1 million rotations per second. One gigahertz represents 1 billion cycles per second.
