To convert gigabits 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.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications.
GB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Gigabits to Bytes.
