millilitre, (kokuji)
竓 is a Japanese-made kanji (kokuji) that represents the metric unit millilitre. Its meaning is specific to that measurement.
竓 is a kokuji created in Japan by combining 立 (stand) and 毛 (hair/fur) to represent the millilitre unit. The exact reasoning behind the component choice is uncertain, but it likely follows the pattern of other metric unit kokuji where 立 suggests a standing measure and 毛 may relate to a small unit.
Imagine a tiny standing measure (立) with a single hair (毛) inside it, representing a very small volume: one millilitre.
For ミリリットル, picture a millilitre of liquid standing in a tiny cup: the word 'millilitre' itself is the reading, so think of the kanji as directly representing that word.
