How many gigabytes is there in one terabyte?

Answer 1

1000 or 1024

When referring to ACTUAL SPACE on a storage device or in memory, each "unit" is 1024 of the previous unit.

1024 bytes = kilobyte

1024 kilobytes = megabyte

1024 megabytes = gigabyte

1024 gigabytes = terabyte

etc.

When selling storage devices (such as CDs or USB drives), the packaging will use a 1000 rule (same as above, but with 1000 instead of 1024), thus giving the appearance of having slightly more capacity. This is considered acceptable because in standard english, the prefixes kilo-, mega-, giga-, use the "1000 rule."

Computers use 1024 because it is the perfect power of 2 closest to 1000. Using a power of 2 is important because computers are binary (base 2) systems.

To help make this difference less ambiguous, a new set of prefixes was proposed to represent powers of 1024 (rather than 1000). They are kibi-, mebi-, gibi-, tebi-, etc.

Answer 2

A yottabyte is 1024 bytes in SI or 280 bytes in binary. This is more than one quadrillion gigabytes.

Answer 3

There are 1,000,000,000,000,000,000,000 bytes in a zettabyte according to The Joy of Stats (TV Program)

That's also called a sextilion.

Answer 4

There are 1,024 gigabytes in one terabyte. Symbols for terabyte and gigabyte are TB and GB, respectively.

Answer 5

1024 GB = 1 TB
