How to Convert Megabits to Gigabytes
To convert megabits to gigabytes, 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. Learn more: Gigabytes to Megabits.
Mb measures data in bits—commonly used for memory addressing and low-level data specifications. See also: Megabits to Bytes converter.
GB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Use our Tebibits to Gigabytes calculator.
1 Mb = 0.000125 GB (using SI decimal standard) — or equivalently, 1 GB = 8,000Mb.
Mb to GB Conversion Formula
// Convert Mb to GB
GB = Mb × 0.000125
// Reverse: Convert GB to Mb
Mb = GB × 8,000Megabit to Gigabyte Conversion Examples
100 Mb = 0.0125 GB
256 Mb = 0.032 GB
500 Mb = 0.0625 GB
1,000 Mb = 0.125 GB
2,048 Mb = 0.256 GB
What Is a Megabit (Mb)? Definition and Uses
