Data Consistency & Unit Standards

Temperature Units: Melting and boiling points are presented in both Kelvin (K) and Celsius (°C), dynamically interpolated from a single source of truth.
Multilingual Nomenclature: Korean follows KS/KCS standards with legacy industrial names in parentheses; Simplified Chinese (zh-CN) and Traditional Chinese (zh-TW) use distinct regional standard characters.
