GB to TB: How to Convert Gigabytes to Terabytes
Learn how to convert gigabytes (GB) to terabytes (TB), understand the difference between decimal and binary storage units, and convert common values quickly.
What Are GB and TB?
GB stands for gigabyte, while TB stands for terabyte. Both are commonly used to describe digital storage capacity and data size.
A terabyte is larger than a gigabyte, so converting GB to TB means expressing the same amount of data using a larger unit.
How Many GB Are in a TB?
Using the decimal storage system, 1 terabyte (TB) equals 1,000 gigabytes (GB).
This means you can convert gigabytes to terabytes by dividing the number of gigabytes by 1,000.
How to Convert GB to TB
To convert gigabytes to terabytes using decimal units, divide the number of gigabytes by 1,000.
For example, 500 GB ÷ 1,000 = 0.5 TB. Similarly, 2,000 GB ÷ 1,000 = 2 TB.
Common GB to TB Conversions
Here are some common decimal conversions:
100 GB = 0.1 TB.
250 GB = 0.25 TB.
500 GB = 0.5 TB.
750 GB = 0.75 TB.
1,000 GB = 1 TB.
2,000 GB = 2 TB.
5,000 GB = 5 TB.
GB to TB Formula
The decimal formula is simple: TB = GB ÷ 1,000.
For example, if you have 3,500 GB, divide 3,500 by 1,000 to get 3.5 TB.
Why Storage Sizes Can Be Confusing
Storage and computing systems can use different unit conventions. Decimal units use powers of 1,000, while binary units use powers of 1,024.
Because of this, a value described informally as a gigabyte may not always correspond to the same number of bytes as a binary gibibyte (GiB). When precision matters, check whether the source is using decimal or binary units.
GB vs TB: Which Is Larger?
A terabyte is larger than a gigabyte. Using decimal units, 1 TB equals 1,000 GB.
This is why storage capacities are often expressed in TB when the amount of data becomes large.
Convert GB to TB Online
If you need to convert different data sizes, you can use the Martools Unit Converter instead of calculating each value manually.
Enter the value in gigabytes, select terabytes as the target unit, and the converter can calculate the result for you.
Final Thoughts
Converting GB to TB is straightforward when using decimal storage units: divide the number of gigabytes by 1,000.
For example, 500 GB is 0.5 TB and 1,000 GB is 1 TB. Always check the unit convention when working with storage values where precision matters.
