How to Convert Gigabytes to Gigabits
To convert gigabytes to gigabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. Check out our Gb to GB conversion rate.
GB is a byte-based unit used for measuring file sizes and storage capacity. Related: converting Gigabytes to Zebibits.
Gb is a bit-based unit—multiply bytes by 8 to get bits. Learn more: Zettabytes in Gigabits.
1 GB = 8 Gb (using SI decimal standard) — which means there are 8gigabits in every gigabyte.
GB to Gb Conversion Formula
// Convert GB to Gb
Gb = GB × 8
// Reverse: Convert Gb to GB
GB = Gb × 0.125
