How to convert gigabytes to terabytes

1 GB = 0.001 TB

1 TB = 1,000 GB exactly (SI prefixes are powers of 10, SI Brochure): divide GB by 1,000. The binary equivalent is 1 TiB = 1,024 GiB exactly.

Examples

  • 500 GB = 0.5 TB: a laptop drive
  • 750 GB = 0.75 TB: a photo library to back up
  • 2,500 GB = 2.5 TB: a video archive measured in gigabytes

  • A drive sold as 1 TB holds 1,000,000,000,000 bytes. Software counting in binary shows about 931 GiB, often labelled "GB", so nothing is missing.

Frequently asked questions

How many GB make 1 TB?

1,000 GB make 1 TB in the decimal system drive makers use. In binary units, 1 TiB is 1,024 GiB.

Is 500 GB half a terabyte?

Yes. In decimal units 500 GB is exactly 0.5 TB. In binary terms it is about 0.455 TiB, which is why some systems show a smaller figure.

How do I convert GB to TB?

Divide by 1,000: 2,500 GB ÷ 1,000 = 2.5 TB. Use 1,024 only when both figures are binary units (GiB to TiB).
