1 Megabit = 0.001 Gigabit

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

Gb = Mb ÷ 1024

A megabit is 1/1024 of a gigabit. At 10 Gbps speeds, even thousands of Mbps aggregate to Gb-level links. Network architects convert Mb to Gb when sizing data center interconnects, planning backbone capacity, or calculating aggregate throughput across many 1G access links.
