1 Gigabit = 1024 Megabit

Key Formulas

Megabyte → Gigabyte

GB = MB × 0.000976563

Gigabyte → Megabyte

MB = GB × 1024

Gigabyte → Terabyte

TB = GB × 0.000976563

Terabyte → Gigabyte

GB = TB × 1024

Formula

Mb = Gb × 1024

A gigabit is 1024 megabits. Network engineers convert Gb to Mb when analyzing link speeds, planning capacity, or debugging issues. A 10G link carries 10,240 Mbps; a 100G link carries 102,400 Mbps. The 1024:1 ratio makes binary conversion straightforward.
