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 = KB ÷ 128

A kilobyte equals 1/128 of a megabit (8192 bits ÷ 1,048,576 bits per Mb = 0.0078125). Network engineers use this when sizing links for file transfers, calculating buffer requirements, or determining protocol overhead. A 1 MB file is 8 Mb, so a 100 Mbps link takes ~80 ms to transmit.
