or a design record (3-4 decimals). Reverse round-trip: A feet-and-inches input returns the same centimeters that， so the result is not an estimate. Adjustable precision: Decimal places from 0 to 4 fit a quick chart line (0-1 decimals)。

a pediatric growth note (2 decimals)， while U.S. adult charts and ID forms use feet and inches. The converter keeps both vocabularies visible. Only U.S. customary feet and inches are supported.
