About

combines the broad shelter radical 广 (guǎng) with (chǐ, a Chinese foot or ruler) to form a unit of measurement. Etymologically, it captures the distance between the fingertips of a person's two outstretched arms, roughly equivalent to a fathom. Typically used for measuring fabric, rope, or depth, the character serves purely as a practical, physical unit of distance and has not developed any secondary metaphorical or abstract meanings.
