How many GB are in a TB (terabyte)?

From NCERT Asked by Anonymous from Seattle, United States 24 Oct 2026, 11:08 AM IST Updated

The answer

There are 1,024 gigabytes (GB) in 1 terabyte (TB).

Why

Computers use the binary system. In this system, each step is a power of 2. So:

  • 1 kilobyte (KB) = 1,024 bytes
  • 1 megabyte (MB) = 1,024 KB
  • 1 gigabyte (GB) = 1,024 MB
  • 1 terabyte (TB) = 1,024 GB

Remember it

Just remember: 1 TB = 1,024 GB. Not 1,000!

Quick recap

  • 1 terabyte (TB) = 1,024 gigabytes (GB).
  • Computers use powers of 2, not 10.
  • Many people wrongly think 1 TB = 1,000 GB.
  • Remember: 1,024 is the magic number for computer storage.
