Frequently asked questions about the file size converter
Why does my 1 TB drive show as 931 GB?+
Manufacturers use decimal units where 1 TB = 1,000,000,000,000 bytes, while operating systems display binary units where 1 TiB = 1,099,511,627,776 bytes. Nothing is missing - the two systems just count differently.
What is the difference between MB and MiB?+
1 MB is 1,000,000 bytes (decimal) and 1 MiB is 1,048,576 bytes (binary). Switch the standard toggle to see both.
