How to convert terabytes to petabytes
To convert a measurement in terabytes to petabytes, multiply the value by 0.001. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 TB to petabytes: 5 × 0.001 = 0.005 PB.
What is a terabyte?
A terabyte is 1,000,000,000,000 bytes (1,000 gigabytes) under the SI decimal convention. The binary equivalent of 1,099,511,627,776 bytes is the tebibyte (TiB). The terabyte moved from data-center jargon to the home as hard drives crossed the 1 TB mark in 2007. It is now the common unit for desktop drives and network-attached storage.
Common uses of terabytes include: Desktop hard drives and external backup drives; Network-attached storage (NAS) systems; Large media and photo libraries; Video production and archival storage.
What is a petabyte?
A petabyte is 1,000,000,000,000,000 bytes (1,000 terabytes) under the SI decimal convention. The binary equivalent is the pebibyte (PiB). The petabyte is the scale of large enterprises and cloud providers. Notable milestones include estimates that major platforms ingest multiple petabytes of new data every day.
Common uses of petabytes include: Data-center and cloud-storage capacity; Big-data analytics and data lakes; Scientific datasets (genomics, astronomy); Large-scale media streaming archives.

Frequently asked questions
How many petabytes are in one terabyte?
One terabyte (TB) equals 0.001 petabytes (PB). Multiply any value in terabytes by 0.001 to convert to petabytes.
How do I convert terabytes to petabytes?
Multiply the value in terabytes by 0.001. For example, 5 TB × 0.001 = 0.005 PB.
How do I convert petabytes to terabytes?
Multiply the value in petabytes by 1,000, or divide by 0.001. Use the swap button on the converter above to reverse the direction.
Is the terabyte to petabyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for terabytes to petabytes?
The formula is: PB = TB × 0.001. This comes from the definition of both units relative to the byte.
