Converting gigabytes and terabytes
Some commonly asked questions are included below, as well as a reference chart. When making manual conversions, you can use the converter at the top of this page to check your answer.
How many terabytes are there in 1 gigabyte?
There are 0.001 terabytes in 1 gigabyte. To convert from gigabytes to terabytes, multiply your figure by 0.001 (or divide by 1000) .
How many gigabytes are there in 1 terabyte?
There are 1000 gigabytes in 1 terabyte. To convert from terabytes to gigabytes, multiply your figure by 1000 (or divide by 0.001) .
In the chart below, figures are rounded to a maximum of 4 decimal places (6 with smaller numbers) to give approximations.
What is a gigabyte?
A gigabyte is the equivalent of 1,000,000,000 bytes. Still, many fields of computer science will refer to this number as 1,073,741,824 (1,024^3) bytes. This second figure will often be used when speaking about different sizes of RAM within an operating system. To make sense out of this large figure, let's use it in reference:
- 1 gigabyte is 1,000 megabytes.
- 1 gigabyte is 1,000,000 kilobytes.
What is a terabyte?
The terabyte is the current heavyweight of all data storage. The terabyte represents 1,000^4 bytes. In other words, it is the equivalent of one TRILLION bytes of information. This can also be expressed in more technical terms as 1,024^4 (1,099,511,627,776) bytes. Thanks to advances in storage and processing power, the terabyte is now commonly seen in external hard drives and other systems which provide massive amounts of memory space. As the world of computing continues to advance, it will be interesting to see how far these massive figures will rise!
