Megahertz to Gigahertz Formula & Unit Definitions
The conversion ratio between megahertz and gigahertz is exactly 1,000 to 1 (1 GHz = 1,000 MHz). To convert megahertz to gigahertz, divide the frequency in megahertz by 1,000 (or multiply by 0.001), shifting the decimal point three places to the left. To perform the reverse conversion from gigahertz back into megahertz, multiply by 1,000 (or divide by 0.001).
Quick Estimation: Divide by 1,000 by moving the decimal point 3 places to the left. For example, 1,000 MHz = 1 GHz; 2,400 MHz (Wi-Fi band) = 2.4 GHz; 5,000 MHz = 5 GHz.
Megahertz Multiple (MHz)
SI Million-Cycle Multiple- Creator & Origin: Adopted under SI and ITU standards to express broadcast radio and legacy personal computer clock frequencies.
