Helpful guide
Unit conversions are most reliable when the source value and unit are identified correctly. Do not confuse similarly named US customary and imperial units, and keep significant figures appropriate to the precision of the original measurement. For engineering, scientific, medical or safety-critical work, confirm the measurement standard required by your application.
Use sensible precision and verify critical decisions with an authoritative source or qualified professional.
