Frequently Asked Questions
What conversion standards are implemented in this tool?
The tool uses international scientific definitions (NIST, BIPM SI standards, and IEEE binary/decimal data storage conventions) to guarantee exact mathematical conversions.
Does the converter handle both binary (1024) and decimal (1000) data standards?
Yes. You can toggle between binary prefix units (KiB, MiB, GiB, TiB using base-2) and standard metric decimal units (kB, MB, GB, TB using base-10).
Can I copy converted values with custom precision formatting?
Yes. Results can be adjusted for decimal precision and copied to your clipboard instantly.
