Tips & Best Practices

Always verify the throughput units correspond to the same measurement context.
Consider network overhead and framing differences when interpreting results.
Use this converter for theoretical equivalence rather than exact real-world throughput.
Refer to examples to ensure correct data entry and conversion interpretation.

Limitations

Conversion reflects theoretical equivalence and does not account for real-world overhead.
IDE (PIO mode 3) throughput is CPU-driven and often lower than theoretical maximum.
STS3c payload throughput is reduced by SONET framing and overhead bytes.
Exact data throughput matching between units is approximate, not precise.
