About the gigabytes to terabytes converter
To convert gigabytes to terabytes, multiply by 0.001; to convert back, multiply by 1,000. For example, 500 GB is about 0.5 TB. Displayed factors and results may be rounded.
Gigabytes may describe a data plan, a collection of files or a drive partition. Converting that allowance helps compare it with a differently labelled quota. Keep decimal GB separate from GiB and distinguish storage capacity from a transfer rate.
Both units are defined exactly. Calculations use 50 significant digits and round only for display.
How to convert GB to TB
Divide the gigabytes by 1,000: TB = GB ÷ 1,000. So 500 GB = 0.5 TB, 2,000 GB = 2 TB and 512 GB = 0.512 TB. Drive makers count in these decimal units, with 1 GB = 10⁹ bytes and 1 TB = 10¹² bytes. Use it to check whether a collection of files fits on a drive or storage plan.
Will your files fit on a TB drive?
Add everything up in GB, divide by 1,000 and compare the result with the drive size. A 600 GB photo library plus 450 GB of video is 1,050 GB, or 1.05 TB, too much for a 1 TB drive.
Leave some margin as well, because the filesystem itself uses part of the drive.

Why Windows folder sizes don't match TB labels
Windows and some other systems count in binary units of 1,073,741,824 bytes but label them GB. If Windows reports your files as 950 GB, they are really 950 GiB, which is 1,020 decimal GB and more than a 1 TB drive holds.
The same counting makes a new 1 TB drive appear as about 931 GB. The binary terabyte is larger again: 1 TiB = 1,024 GiB = 1.099511627776 TB (NIST).
How long does a TB take to upload?
The same total sets how long a cloud backup will take. 1 TB is 8,000,000 megabits, so a 100 Mbps upload needs 80,000 seconds, about 22 hours, before any overhead. At 20 Mbps the same backup takes about 4.6 days.
The download time calculator works this out for other sizes and speeds, including upload links.
Common mistakes
- Dividing by 1,024. In decimal units 1,024 GB is 1.024 TB, not 1 TB. The 1,024 ratio applies to GiB and TiB.
- Comparing a GiB total with a TB label. Convert the folder size to decimal GB first, as above, or the new drive can come up short.
Related conversions
For the reverse step, use TB to GB, and start from megabytes with MB to GB. The data storage converter converts GiB and TiB directly, and the RAID calculator works out usable space across several drives.

Questions
What fraction of a terabyte is 500 GB?
500 GB in decimal units is 0.5 TB. Divide the gigabyte amount by 1,000 when comparing file totals with a terabyte quota. Keep the same decimal convention on both sides of the comparison.
How many terabytes are in one gigabyte?
1 GB is about 0.001 TB.
How do I convert gigabytes to terabytes?
Multiply by 0.001: 500 GB × 0.001 ≈ 0.5 TB. 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).
