How to Convert Gigabits to Megabytes
To convert gigabits to megabytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. Try the Megabytes to Gigabits calculator.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications. See also: Gigabits to Exbibytes converter.
MB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Learn more: Kilobytes to Megabytes.
1 Gb = 125 MB (using SI decimal standard) — which means there are 125megabytes in every gigabit.
Gb to MB Conversion Formula
// Convert Gb to MB
MB = Gb × 125
// Reverse: Convert MB to Gb
Gb = MB × 0.008Gigabit to Megabyte Conversion Examples
100 Gb = 12,500 MB
256 Gb = 32,000 MB
500 Gb = 62,500 MB
1,000 Gb = 125,000 MB
2,048 Gb = 256,000 MB
What Is a Gigabit (Gb)? Definition and Uses
A gigabit is 1,000 megabits or 1,000,000,000 bits. Used for high-speed network connections. Check out our Pib → Yib.
The gigabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: convert KB/s to GiB/s.
