About the terabytes to gigabytes converter
To convert terabytes to gigabytes, multiply by 1,000; to convert back, multiply by 0.001. For example, 2 TB is about 2,000 GB. Displayed factors and results may be rounded.
Terabyte drive labels are useful for estimating the advertised capacity of a disk or storage plan in gigabytes. This decimal conversion does not subtract formatting overhead or space reserved by a filesystem. An operating system may display a binary unit with a similar-looking label.
Both units are defined exactly. Calculations use 50 significant digits and round only for display.
How to convert TB to GB
Multiply the terabytes by 1,000: GB = TB × 1,000. A 2 TB drive or storage plan is 2,000 GB, 4 TB is 4,000 GB and 0.5 TB is 500 GB. These are the decimal units drive makers use, with 1 TB = 10¹² bytes and 1 GB = 10⁹ bytes. Use it to see what a TB label gives you in GB.
Is 1 TB 1,000 GB or 1,024 GB?
In decimal units, the ones on drive labels, 1 TB is exactly 1,000 GB. The 1,024 ratio belongs to binary units: 1 TiB = 1,024 GiB, which is 1099.511627776 decimal GB (NIST).

Why a new drive shows fewer GB
Windows and some other systems count in binary gigabytes of 1,073,741,824 bytes but still label them GB. Dividing a drive's bytes by that number gives the size they display:
- 1 TB → about 931 GiB
- 2 TB → about 1,863 GiB
- 4 TB → about 3,725 GiB
- 8 TB → about 7,451 GiB
None of the capacity is missing; the same bytes are counted in a larger unit. The filesystem also takes some space, so a new drive's free space is a little less than its total size.
How much fits on a TB drive?
Convert the capacity to GB, then divide by the size of each item. A 2 TB drive holds 2,000 GB, which is at most forty 50 GB games or 400,000 photos of 5 MB.
Item sizes copied from Windows are GiB, though. A 2 TB drive is 1,862.6 GiB, so at most 37 games of 50 GiB fit.
Common mistakes
- Multiplying by 1,024. 2 TB × 1,024 = 2,048 GB, which overstates a decimal 2 TB drive by 48 GB.
- Confusing terabytes with terabits. A lowercase b means bits: 1 Tb is 125 GB.
Related conversions
For the reverse step, use GB to TB; to continue to megabytes, use GB to MB. The data storage converter converts TiB and GiB directly, and the download time calculator estimates how long a cloud backup of a given size takes.

Questions
Does a 2 TB plan provide 2,000 GB or 2,048 GB?
A decimal 2 TB plan represents 2,000 GB. The number 2,048 belongs to converting 2 TiB into GiB. Check the provider's unit labels before using a binary factor to compare an advertised storage allowance.
How many gigabytes are in one terabyte?
1 TB is about 1,000 GB.
How do I convert terabytes to gigabytes?
Multiply by 1,000: 2 TB × 1,000 ≈ 2,000 GB. To convert back, divide by the same factor. The factor shown may be rounded.
Why does my computer show less space than the drive's label?
Drive makers count 1 GB as 1,000,000,000 bytes, while Windows and some other systems count in binary units of 1,073,741,824 bytes but still label them GB. A 1 TB drive therefore appears as about 931 GB (really 931 GiB).
