About Gigabyte and Gigabit
The gigabyte is an SI decimal data unit equal to exactly 1,000 megabytes, or one billion bytes. Device storage and mobile data plans are commonly sold in gigabytes. The gigabit is an SI decimal data unit equal to 1,000 megabits, or 125,000,000 bytes. Fiber connections and modern network hardware operate at gigabit scales. One Gigabyte equals 8 Gigabits (1 GB = 8 Gbit). Gigabyte is used in phone and laptop storage and in cloud storage quotas. Gigabit is used in fiber internet plans.
Precision and Rounding:This converter keeps SI decimal prefixes (1 KB = 1,000 bytes) separate from IEC binary prefixes (1 KiB = 1,024 bytes). Match the symbol used by your source before converting because some operating-system interfaces display binary quantities with decimal labels.
See our guide to megabits vs. megabytes if you're unsure which one your download speed is quoted in.
Data units follow NIST guidance: decimal SI prefixes use powers of 1,000, while IEC binary prefixes use powers of 1,024 (reference).
