Gibibytes to Petabytes (GiB to PB)
1 gibibyte equals 0.000001073741824 petabytes exactly.
How to convert gibibytes to petabytes
To convert gibibytes to petabytes, multiply the number of gibibytes by 0.000001073741824. This factor is exact. To go the other way, multiply petabytes by 931,322.5746 (rounded).
petabytes = gibibytes × 0.000001073741824
Example: 10 gibibytes = 0.00001073741824 petabytes.
Decimal prefixes (kB, MB, GB) are powers of 1,000; binary prefixes (KiB, MiB, GiB) are powers of 1,024. Storage makers use decimal; Windows reports binary but labels it GB.
About these units
Gibibyte (GiB)
Exactly 1,073,741,824 bytes (2³⁰), about 7.4% larger than a gigabyte. Windows displays this as 'GB', which is why a 500 GB drive appears as about 465 GB.
Gibibyte is the unit that explains why a new drive looks smaller than its box says. It is the IEC name, from December 1998, for 2 to the thirtieth bytes, or 1,073,741,824 bytes, chosen to denote powers of 1,024 unambiguously. A GiB is about 7.4 percent larger than a decimal gigabyte, so a drive advertised as 500 GB holds 500 billion bytes, which is about 465.7 GiB.
Windows reports that number with the label GB, so users see a shortfall. RAM is still counted in the binary sense, while hard drives, SSDs, flash media and optical discs are usually labeled in decimal units. Courts have held that the legal definition of GB is the decimal one. The symbol GiB is formed by adding an i to GB, and apart from KDE and Qt-based applications it is rarely used in practice.
1 gibibyte = 1,073,741,824 bytes (exactly).

Petabyte (PB)
1,000 terabytes (10¹⁵ bytes). The scale of large data centers.
Peta entered the SI in 1975, when the General Conference on Weights and Measures approved peta and exa in its Resolution 10. A petabyte is 10 to the fifteenth bytes, or 1,000 terabytes, and the word is formed by attaching that prefix to byte, a term Werner Buchholz coined in June 1956 as a deliberate respelling of bite. The binary counterpart is the pebibyte: the IEC amendment published in January 1999 added pebi and exbi to the earlier binary names.
Decimal units dominate at this size: hard drives, SSDs, optical discs and network contracts all use powers of 1,000, and macOS, iOS, Android and Ubuntu follow suit. As an example of the size, one petabyte is about 2,000 years of MP3-encoded music at roughly one megabyte per minute. Binary use of the P symbol is less common than for smaller prefixes.
1 petabyte = 1×10¹⁵ bytes (exactly).
