How to Convert Gigabits to Gigabytes
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. Check out our Gigabytes to Gigabits calculator.
Gb measures data in bits—commonly used for memory addressing and low-level data specifications. You might also need: convert Gigabits to Gibibits.
GB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. You might also need: Pebibits to Gigabytes conversion.
1 Gb = 0.125 GB (using SI decimal standard) — or equivalently, 1 GB = 8Gb.
Gb to GB Conversion Formula
// Convert Gb to GB
GB = Gb × 0.125
// Reverse: Convert GB to Gb
Gb = GB × 8Gigabit to Gigabyte Conversion Examples
100 Gb = 12.5 GB
256 Gb = 32 GB
500 Gb = 62.5 GB
1,000 Gb = 125 GB
2,048 Gb = 256 GB
