About Petabyte and Gigabyte
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. 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. One Petabyte equals 1000000 Gigabytes (1 PB = 1000000 GB). Petabyte is used in data center capacity and in scientific research datasets. Gigabyte is used in phone and laptop storage.
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).
