U+515B "兛" CJK Unified Ideograph-# Unicode Character

U+515B "兛" CJK Unified Ideograph-# is a Chinese character primarily used as a unit symbol for the kilogram in Japanese contexts, where it is known as the "kiroguramu" or "kiro" kanji, combining the radical for "legs" or "to support" with a phonetic element to represent the metric weight. Originating from Japan's adoption of the metric system, this character is a relatively rare and unique ideograph that was created by repurposing existing CJK components rather than being derived from classical Chinese usage. It serves as a specialized character for scientific and technical writing, appearing in contexts such as weight measurements on packaging or in documentation, though it is not widely used in modern standard Chinese.
