Converting Terabytes to Gigabytes
What are Terabytes and Gigabytes?
A terabyte (TB) is a unit of digital information equal to 1,024 gigabytes or about 1 trillion bytes. It is commonly used to describe the capacity of modern hard drives, SSDs, and cloud storage plans.
A gigabyte (GB) is a unit of digital information equal to 1,024 megabytes. Converting TB to GB helps understand how much data you can store in terms of individual files and applications.
Terabytes to Gigabytes Formula
To convert terabytes to gigabytes, use this formula:
Gigabytes = Terabytes × 1024
Practical Conversion Examples
- 1 TB = 1,024 GB
- 2 TB = 2,048 GB
- 4 TB = 4,096 GB
- 10 TB = 10,240 GB
Common Applications
- Hard drives: understanding actual usable storage
- Cloud storage: planning data backup capacity
- NAS systems: configuring network storage arrays

About "Terabytes to Gigabytes" Calculator
This converter will help you convert Terabytes to Gigabytes (TB to GB). The conversion uses the binary standard where 1 TB = 1,024 GB (2^10). For example, it can help you find out how many gigabytes is 1 TB? (The answer is: 1,024). Enter the number of terabytes (e.g. '1') and hit the 'Convert' button. The formula is simple: multiply the number of terabytes by 1,024 to get the equivalent in gigabytes. Note that some storage manufacturers use the decimal definition (1 TB = 1,000 GB), while operating systems typically use the binary definition shown here.
FAQ
How many gigabytes are in a terabyte?
In the binary convention used by Windows and most operating systems, 1 TB = 1024 GB, and that is what this converter applies. Drive manufacturers use the decimal convention instead, where 1 TB = 1000 GB.
Why does a 1 TB drive show only 931 GB?
The label counts 1 TB as 1,000,000,000,000 bytes, while the operating system divides that figure by 1024 three times: 1,000,000,000,000 ÷ 1024³ = 931.32. No space goes missing — the two sides simply count in different units.
What is the difference between GB and GiB?
A gibibyte (GiB) is exactly 1024³ bytes, the IEC unit, while a gigabyte in the strict SI sense is 1000³ bytes. Everyday usage calls 1024³ bytes a gigabyte, and this converter follows that everyday convention.
