Frequently Asked Questions
Which unit definitions are used?
Exact SI-defined factors: 1 inch = 2.54 cm, 1 pound = 0.45359237 kg, 1 mile = 1609.344 m, and binary data units where 1 KiB = 1024 bytes with the KB/MB labels reported alongside their decimal 1000-based values.
Why does the tool show two answers for file sizes?
Because storage vendors and operating systems disagree. A "1 MB" drive is 1,000,000 bytes while Windows reports it as 0.95 MiB, so both the decimal and binary results are given instead of picking a side.
