To convert gigabytes to terabytes, divide by 1024. In binary, 1 TB = 1024 GB, so 1 GB = 1/1024 ≈ 0.000977 TB:
Some manufacturers use decimal: 1 TB = 1,000 GB. This converter uses binary (1024), which is how operating systems report storage.
Common storage sizes in GB and TB:
To convert gigabytes to terabytes, divide by 1024. In binary computing terms, 1 TB = 1024 GB, so 1 GB = 1 ÷ 1024 ≈ 0.000977 TB. For example, 500 GB = 500 ÷ 1024 ≈ 0.4883 TB, and 2048 GB = 2 TB exactly.
Some storage manufacturers use decimal prefixes where 1 TB = 1,000 GB. This is why a "2 TB" hard drive may show as about 1.82 TB in Windows (which uses binary). For most computing and software purposes, 1 TB = 1024 GB is the standard used here.
You'll need this conversion when buying or comparing hard drives and SSDs, planning cloud storage or backup capacity, understanding server storage quotas, or calculating how much storage a large media library or database will require. It is particularly useful when dealing with large data sets where GB numbers become unwieldy and terabytes are more practical.
There are 1,024 gigabytes (GB) in one terabyte (TB) in binary computing terms. Storage manufacturers often define 1 TB as 1,000 GB (decimal/SI), which is why drives appear smaller than advertised when shown by your operating system.
500 GB = 500 ÷ 1024 ≈ 0.4883 TB. It is slightly less than half a terabyte. In decimal terms, 500 GB = 0.5 TB (500 ÷ 1000).
Yes, in binary (computing) terms, 1 TB = 1,024 GB exactly. This is how operating systems like Windows and macOS report storage. Storage manufacturers sometimes use 1 TB = 1,000 GB (decimal), which creates the apparent discrepancy in advertised vs reported storage.
2 TB = 2 × 1024 = 2,048 GB. A 2 TB hard drive should hold 2,048 GB of data in binary terms. However, a '2 TB' drive sold using decimal measurement is actually 2,000 GB, which shows as about 1,862 GB in Windows.
