How this is calculated
This uses the decimal (SI) standard that drive makers use, where 1 terabyte equals 1000 gigabytes. Gigabytes are divided by 1000 to get terabytes. A drive sold as 1 TB shows less usable space in an operating system that counts in binary units (1 TiB = 1024 GiB).
How to use
- Enter the number of gigabytes.
- Keep the direction on GB to TB, or press Swap units for TB to GB.
- Read the result in terabytes.
Examples
- One terabyte:
1000 GB = 1 TB - Half a terabyte:
500 GB = 0.5 TB - TB back to GB:
2 TB = 2000 GB
