About the units
- Gibibyte
- A binary unit equal to exactly 2^30 = 1,073,741,824 bytes. Windows labels it as GB.
- Terabyte
- A decimal unit equal to exactly 10^12 bytes, which is 1000 decimal gigabytes.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many terabytes are in one gibibyte?
1 GiB = 0.00107374 TB exactly.
How do I convert gibibytes to terabytes?
Use TB = GiB × 0.001073741824. For example, 25 GiB = 0.0268435 TB.
How many gibibytes are in one terabyte?
1 TB = 931.323 GiB.
Why does a 1 TB drive show about 931 GB on my computer?
Drive makers count 1 TB as 10^12 bytes, while Windows divides by 2^30 and labels the result GB even though it is really GiB. So 10^12 ÷ 1,073,741,824 gives about 931.32, and no space is missing.
What is the difference between a kilobyte and a kibibyte?
A kilobyte (kB) is a decimal unit of 1000 bytes and a kibibyte (KiB) is a binary unit of 1024 bytes. The same split applies to mega and mebi, giga and gibi, and the gap grows at each step.
