About This Conversion
Megahertz to gigahertz divides by 1,000. The conversion turns up wherever radio and processor specifications mix the two prefixes, which they do constantly: a band listed as 2400 MHz and a router advertised at 2.4 GHz are the same thing.
The bands worth recognising sit in this table. Mobile networks use 700, 900, 1800 and 2600 MHz; Wi-Fi uses 2.4 and 5 GHz; the licence-free LoRa bands are 433 and 868 MHz. Lower frequencies travel further and penetrate walls better, which is why 900 MHz covers a farm and 5 GHz struggles across a house.
Memory speeds are the confusing exception. DDR5-6000 is sold by its data rate, 6,000 megatransfers per second, not by its clock, which is 3,000 MHz or 3 GHz because data moves twice per cycle. When a system tool reports half the number on the box, that is why.
Frequently Asked Questions
How many MHz are in a GHz?
One gigahertz is 1,000 megahertz.
What is 2400 MHz in GHz?
2,400 MHz is 2.4 GHz, the common Wi-Fi band.
What is 5800 MHz in GHz?
5,800 MHz is 5.8 GHz.
Is a higher frequency better for Wi-Fi?
Higher frequencies carry more data but travel less far. 5 GHz is faster nearby; 2.4 GHz reaches further.
