Formula
Formula
PB = Tbit × 0.000125
Multiply any value in terabits by 0.000125 to obtain the value in petabytes.
Worked example
Convert 8000 Tbit to PB.
- 01Start with 8000 Tbit.
- 02Multiply by the conversion factor: 8000 × 0.000125 = 1 PB.
Result8000 Tbit = 1 PB

FAQ
What is the conversion factor from Tbit to PB?
1 Tbit equals 0.000125 PB. To convert, multiply the value in terabits by 0.000125.
How do I convert 1 Tbit to PB?
1 Tbit = 0.000125 PB. For any value, multiply by 0.000125.
How do I convert PB back to Tbit?
Divide by the same factor — or equivalently, multiply by 8000. So 1 PB = 8000 Tbit.
When would I need to convert terabit to petabyte?
Digital data-storage conversions between Tbit and PB are routine in IT, networking, storage-array engineering, datacenter capacity planning, cloud-cost reconciliation, embedded systems and scientific data acquisition. Decimal (SI) units (kB, MB, GB, TB, PB) use base-10 multiples: 1 kB = 1,000 bytes. Binary (IEC 80000-13) units (KiB, MiB, GiB, TiB, PiB) use base-2 multiples: 1 KiB = 1,024 bytes. 1 byte = 8 bits exactly across both ladders. This category is storage size only — it does NOT cover data-transfer rate (bit/s, MB/s), download-time, bandwidth, compression-ratio assumptions or storage-pricing calculators, all of which require additional information beyond a single linear factor.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
