Petabyte quick reference
| Petabyte | Gigabyte | Gibibyte | Bit |
|---|---|---|---|
| 1 PB | = 1000000 GB | ≈ 931322.5746 GiB | = 8e+15 bit |
| 10 PB | = 10000000 GB | ≈ 9313225.746 GiB | = 8e+16 bit |
| 100 PB | = 100000000 GB | ≈ 93132257.46 GiB | = 8e+17 bit |
| 1000 PB | = 1000000000 GB | ≈ 931322574.6 GiB | = 8e+18 bit |
Where the petabyte fits
The next smaller data storage unit is the tebibyte (TiB). 1 PB ≈ 909.4947018 TiB, and 1 TiB = 0.001099511627776 PB.
The next larger data storage unit is the pebibyte (PiB). 1 PB ≈ 0.8881784197 PiB, and 1 PiB = 1.125899906842624 PB.
