Petabytes to Terabytes
A petabyte is 1,000 terabytes, a scale used by data centers and large-scale cloud storage systems. A terabyte is 1,000 gigabytes, the typical size for hard drives and cloud storage plans today. 1 PB equals 1,000 TB, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to data, measured here against data's base unit (bit) — every other data unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
TB = PB × 1,000
PB = TB × 0.001
Worked example: 5 PB × 1,000 = 5,000 TB.
