About this tool
Storage vendors use decimal units where 1 GB is 1,000,000,000 bytes; operating systems often report binary units where 1 GiB is 1,073,741,824 bytes. The gap is 7.4% at terabyte scale.
Decimal vs binary
Use GB for marketing and billing, GiB for memory and filesystem reporting. Always state which you mean in capacity planning docs.
Bits vs bytes
Network throughput is quoted in bits per second. Divide by eight to compare against file sizes in bytes.

Best practices
- Treat every result as a snapshot — configuration drifts, so re-check after each deploy.
- Fix the highest-impact finding first rather than chasing a perfect score.
- Apply changes at the shared layer (proxy, CDN, base image) so every service inherits them.
- Document what you changed and when; auditors and future teammates will ask.
Why Data Size Converter matters
Infrastructure and security misconfigurations are among the most common root causes of real incidents, and almost all of them are cheap to fix once visible.
Leaving them unaddressed means failed audits, blocked enterprise deals, and avoidable exposure.
