Conversion Hub — Units & Currency (Educational)
Conversion hub: unit conversion workflows plus currency conversion guidance with clear disclaimers and verification tips.
Convert units for learning, engineering checks, and homework—then double-check dimensional consistency. For currency, treat results as educational estimates and verify live rates.
Important: Educational use only. Unit conversions are exact when definitions are exact; currency conversions depend on rate sources and timing. Verify before real decisions.

FAQ
Why can two currency converters disagree?
They may use different sources, refresh times, or fee assumptions. Treat results as approximate and verify with a primary source for real transactions.
What’s a quick unit-conversion sanity check?
Use dimensional analysis: make sure units cancel correctly and the magnitude is plausible (e.g., cm should be smaller than meters by 100×).
Tip: If you’re learning, keep your assumptions and intermediate steps in Notebook.
