U+74F1 "瓱" CJK Unified Ideograph-# Unicode Character

U+74F1 "瓱" CJK Unified Ideograph-# is a rare and specialized East Asian ideograph used primarily in Japanese contexts, where it is a kokuji, or a character of Japanese origin rather than one directly borrowed from Chinese. This character is composed of the radical for "stone" or "millstone" on the left and a phonetic or semantic element on the right, and it represents a unit of measurement for weight, specifically the milligram. It is sometimes encountered in older Japanese technical or scientific texts, where it denotes one thousandth of a gram, though its usage has largely been supplanted by the metric system and more common characters in modern Japanese.
