Frequently Asked Questions
How do I convert between byte, KB, MB, GB?
Enter a value and pick its unit — you'll see the equivalent in every other unit at the same time.
Does this use base-1024 or base-1000?
The binary (base-1024) standard is used — the most common convention seen in operating systems' file size displays.
Why do I sometimes see a different size in my file manager?
Some systems use base-1000 (decimal) calculation, which can cause small discrepancies — this isn't an error.
Is this useful when planning large file transfers?
Yes, for example seeing a file's size in MB when given in GB helps estimate download/upload time.
