About Gigabyte and Petabyte

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 petabyte is an SI decimal data unit equal to exactly 1,000 terabytes, or one quadrillion bytes. Data centers, scientific datasets, and cloud platforms operate at petabyte scale. One Gigabyte equals 0.000001 Petabytes (1 GB = 0.000001 PB). Gigabyte is used in phone and laptop storage and in cloud storage quotas. Petabyte is used in data center capacity.

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).
