How to Convert Bytes, KB, MB, GB and TB

To convert data storage sizes, enter a value and choose units in the Data Storage Converter. It supports decimal units used by drive makers, where 1 KB is 1,000 bytes, so 1 GB is 1,000,000,000 bytes.

How to use the Data Storage Converter

  1. Enter the size.
  2. Choose the starting unit.
  3. Choose the target unit.
  4. Read the result.

Worked example

A 500 GB drive is 500,000,000,000 bytes in decimal units, and 0.5 TB.

Tips and common mistakes

  • Operating systems sometimes report sizes in binary units, where 1 GiB is 1,073,741,824 bytes, which is why a drive can look smaller than advertised.
  • 8 bits make 1 byte.
  • Internet speeds are usually in bits per second, storage in bytes.
