A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage.
View the petabyte data unit pageHow to Convert Terabytes to Petabytes
To convert terabytes to petabytes, divide by 1,000 (using SI decimal). Both units measure storage capacity—the difference is scale.
TB: A terabyte is 1,000 gigabytes or 1,000,000,000,000 bytes. Common size for modern hard drives and SSDs.

TB to PB Conversion Formula
Here's the exact TB to PB formula in copy-paste-ready form — multiply by 0.001 to go from terabytes to petabytes, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert TB to PB
PB = TB × 0.001
// Reverse: Convert PB to TB
TB = PB × 1,000

SI Decimal vs Binary: Why Two Different Standards?
When converting terabytes to petabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.
Want to skip the ambiguity entirely? Tebibyte (TiB) and Pebibyte (PiB) are the IEC binary-only siblings of terabyte and petabyte — always base 1,024, no dual-standard guessing. See the TiB to PiB converter.
FAQs: Terabyte to Petabyte Conversion
How many petabytes are in 1 terabyte?
1 Terabyte (TB) equals 0.001 Petabytes using the SI decimal standard, or 0.0009765625 PB using the binary (IEC) standard.
How do I convert terabytes to petabytes?
Multiply the terabyte value by 0.001 to get petabytes. For example, 10 TB = 0.01 PB.
Is a terabyte bigger than a petabyte?
No. 1 TB = 0.001 PB, so the petabyte is larger — 1 PB = 1,000 TB.
What is Terabyte (TB) commonly used for?
External hard drives, NAS storage, video libraries, enterprise backups.
