# How many GB are in a TB?

The gigabyte (abbreviated "GB") is a multiple of the unit byte for digital information, equal to one thousand million bytes. It is also equivalent to 1,073,741,824 bytes in binary.

Terabyte (abbreviated “TB”) is the unit of digital information equal to 1,000,000,000,000 bytes in decimal and 1,099,511,627,776 bytes in binary system. It also means that one terabyte is one trillion bytes. Terabyte is generally used for measuring the amount of digital information in digital archives, online libraries, etc. Hitachi, a Japanese multinational technology company announced the world's first one terabyte hard disk drive in 2007. This unit of measurement is going to be more widely used in the near future.

One terabyte is one thousand bigger than a gigabyte. 1 TB is equal to 10^{12} bytes or 1000^{4} bytes in decimal (base 10). Besides, 1 Terabyte is 2^{40} bytes or 1024^{4} bytes in binary (base 2).

We can also say that 1 TB is equivalent to 1000^{1} gigabytes in decimal. On the other hand, one terabyte is 2^{10} gigabytes or 1024 gigabytes in binary (base 2) system.

So there are 1,000 GB in a TB in decimal and 1,024 GB in a TB in binary system.

**How much is 16 GB in MB? And how much is 32 GB in MB?**

The gigabyte is a multiple of the unit byte for digital information with the prefix Giga. It is one of the most commonly used units in computer science. One gigabyte is equivalent to 1000 megabytes or 10^{3} MB in base 10 (SI). As well as, 1 gigabyte is equal to 1024 megabytes or 2^{10} MB in base 2.

1 gigabyte is one thousand times bigger than a megabyte. So, if we calculate we get the answer as 16 x 1000 = 16000 MB and 32 x 1000 = 32000 MB. But we know that one gigabyte is 1024 megabytes in base 2. So, 16 GB is also equal to 16384 MB, and 32 GB is equal to 32768 MB in binary.

**Check these examples**:

8GB RAM = 8000 MB (in base 10)

8GB RAM = 8192 MB (in base 2)

16GB RAM = 16000 MB (in base 10)

16GB RAM = 16384 MB (in base 2)

32GB RAM = 32000 MB (in base 10)

32GB RAM = 32768 MB (in base 2)

64 GB SSD = 64000 MB (in decimal)

64 GB SSD = 65536 MB (in binary)

128 GB SSD = 128000 MB (in decimal)

128 GB SSD = 131072 MB (in binary)
