#### How many Gigabytes in a Terabyte?

1 terabyte is made up of 1024 gigabytes (binary)

1 TB = 210 GB in base 2

1 terabyte is made up of 1000 gigabytes (decimal)

1 TB = 103 GB in base 10 (SI)

A terabyte (TB) is greater than a gigabyte (GB) – It is 1000 times bigger than a gigabyte.

#### How to convert terabytes to Gigabytes in SI

1 terabyte = 10004 bytes

Since 1GB = 10003, it means that 1 byte = 1000-3 gigabytes

1 Terabyte = 10004 x 1000-3 GB

1 Terabyte = 10001 Gigabytes

1 Terabyte = 1000 Gigabytes

#### How to convert terabytes to gigabytes in base 2

1 Terabyte = 240 bytes

1 Terabyte = 10244 bytes

1 byte = 1024-3 GB

1 Terabyte = 10244 x 1024-3 GB

1 Terabyte = 10241 Gigabytes

1 Terabyte = 210 Gigabytes

1 Terabyte = 1024 Gigabytes
