Rendered to 6 significant figures.
Formula
Formula
Tbit = GB × 0.008
Multiply any value in gigabytes by 0.008 to obtain the value in terabits.
Worked example
Convert 125 GB to Tbit.
- 01Start with 125 GB.
- 02Multiply by the conversion factor: 125 × 0.008 = 1 Tbit.
Result125 GB = 1 Tbit

FAQ
What is the conversion factor from GB to Tbit?
1 GB equals 0.008 Tbit. To convert, multiply the value in gigabytes by 0.008.
How do I convert 1 GB to Tbit?
1 GB = 0.008 Tbit. For any value, multiply by 0.008.
How do I convert Tbit back to GB?
Divide by the same factor — or equivalently, multiply by 125. So 1 Tbit = 125 GB.
When would I need to convert gigabyte to terabit?
Digital data-storage conversions between GB and Tbit 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).
