View the megabit data unit pageHow to Convert Gigabytes to Megabits
To convert gigabytes to megabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units.
GB is a byte-based unit used for measuring file sizes and storage capacity.
Mb is a bit-based unit—multiply bytes by 8 to get bits. Related: Bytes to Petabytes.
1 GB = 8,000 Mb (using SI decimal standard) — which means there are 8,000megabits in every gigabyte.
GB to Mb conversion rate: 1 gigabyte equals 8,000megabits — the standard gigabyte to megabit data storage conversion used by this calculator.
