Factor1 GB = 1e-6 PB

Converter

GB

Accepts numbers or expressions, e.g. 150 + 14.7

Result
1PB

Rendered to 6 significant figures.

Formula

Formula
PB = GB × 1e-6

Multiply any value in gigabytes by 1e-6 to obtain the value in petabytes.

Worked example

Convert 1.00000e+6 GB to PB.

  1. 01Start with 1.00000e+6 GB.
  2. 02Multiply by the conversion factor: 1.00000e+6 × 1e-6 = 1 PB.
Result1.00000e+6 GB = 1 PB

FAQ

What is the conversion factor from GB to PB?
1 GB equals 1e-6 PB. To convert, multiply the value in gigabytes by 1e-6.
How do I convert 1 GB to PB?
1 GB = 1e-6 PB. For any value, multiply by 1e-6.
How do I convert PB back to GB?
Divide by the same factor — or equivalently, multiply by 1000000. So 1 PB = 1.00000e+6 GB.
When would I need to convert gigabyte to petabyte?
Digital data-storage conversions between GB 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).
