A terabyte (TB) is a widely used unit for measuring digital data and is one of the more common sizes in the spectrum of digital data sizes. With the steady increase in data production and the need for more storage space, the terabyte has become important in many technological and everyday applications. One terabyte is equivalent to 1,024 gigabytes (GB).

Nowadays, the terabyte is a standard unit used to measure storage and capacity. It is present in many technology products and services and symbolizes the enormous amount of data that is processed and stored in today's digital world. When converting to other units, a distinction must be made between the binary and decimal systems.

Use of the terabyte:

  • Hard disks and SSDs: many modern hard disks and solid state drives (SSDs) for computers and laptops have storage capacities in the terabyte range.

  • Data centers: Companies and service providers often use storage in the terabyte range to process and back up their customers' and users' data.

  • Multimedia libraries: People with extensive collections of films, music or photos often need terabytes of storage space.

  • Backups and archives: Large-scale backups by companies, organizations or even private users are often in the terabyte range.

Conversion to other data units:

The terabyte can be based on the binary system (factors of 1,024) or the decimal system (factors of 1,000), depending on the context:

  • Petabyte (PB):
    • Binary system: 1 PB = 1,024 TB
    • Decimal system: 1 PB = 1,000 TB
  • Gigabyte (GB):
    • Binary system: 1 TB = 1,024 GB
    • Decimal system: 1 TB = 1,000 GB
  • Megabyte (MB):
    • Binary system: 1 TB = 1,048,576 MB
    • Decimal system: 1 TB = 1,000,000 MB
  • Kilobyte (KB):
    • Binary system: 1 TB = 1,073,741,824 KB
    • Decimal system: 1 TB = 1,000,000,000 KB

It should be noted that the binary system is more commonly used in IT and operating systems. The decimal system, on the other hand, is often used by storage manufacturers and in marketing contexts.
