View the megabyte data unit pageHow 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.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications.
MB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers.
1 Gb = 125 MB (using SI decimal standard) — which means there are 125megabytes in every gigabit.
Gb to MB conversion rate: 1 gigabit equals 125megabytes — the standard gigabit to megabyte data storage conversion used by this calculator.

Gb to MB Conversion Formula
Here's the exact Gb to MB formula in copy-paste-ready form — multiply by 125 to go from gigabits to megabytes, or by 0.008 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert Gb to MB
MB = Gb × 125
// Reverse: Convert MB to Gb
Gb = MB × 0.008
