Frequently Asked Questions — Data Storage Converter
What is the difference between MB and MiB?
MB (megabyte) in the decimal system equals 1,000,000 bytes (10^6). MiB (mebibyte) in the binary system equals 1,048,576 bytes (2^20). Hard drive manufacturers use decimal MB while operating systems often display binary MiB, which is why a 500 GB drive shows as about 465 GiB in your OS.
How many gigabytes are in a terabyte?
In the decimal system, 1 TB equals 1,000 GB. In the binary system, 1 TiB equals 1,024 GiB. The converter handles both systems so you can see exact values for your preferred base.
Why does my hard drive show less space than advertised?
Hard drive manufacturers measure capacity in decimal gigabytes (1 GB = 1 billion bytes) while operating systems display binary gibibytes (1 GiB = 1,073,741,824 bytes). This difference means a 1 TB drive shows approximately 931 GiB in your OS. The converter helps you understand these differences.
