The Conversion Factor
1 gigahertz (GHz) equals exactly 1,000 megahertz (MHz). The prefix 'giga' means billion, while 'mega' means million. Frequency measures how many cycles occur per second - MHz measures millions of cycles per second, while GHz measures billions of cycles per second.
Quick Mental Math
To convert MHz to GHz, divide by 1000 (move decimal point 3 places left). To convert GHz to MHz, multiply by 1000 (move decimal point 3 places right). Example: 3200 MHz = 3.2 GHz, or 2.4 GHz = 2400 MHz.

History of Frequency Measurement
The hertz (Hz) unit was named after Heinrich Hertz, who first proved the existence of electromagnetic waves in the 1880s. As technology advanced and frequencies increased, the prefixes 'mega' (million) and 'giga' (billion) were adopted.
The first microprocessors in the 1970s ran at just a few MHz. Today's processors operate at several GHz, representing a million-fold increase in speed. WiFi technology started at 2.4 GHz (2400 MHz) and has expanded to 5 GHz (5000 MHz) and now 6 GHz (6000 MHz) bands.
