FAQ

What is the conversion factor from TB to PiB?
1 TB equals 0.0008881784 PiB. To convert, multiply the value in terabytes by 0.0008881784.
How do I convert 1 TB to PiB?
1 TB = 0.000888178 PiB. For any value, multiply by 0.0008881784.
How do I convert PiB back to TB?
Divide by the same factor — or equivalently, multiply by 1125.9. So 1 PiB = 1125.9 TB.
When would I need to convert terabyte to pebibyte?
Digital data-storage conversions between TB and PiB 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).
