A Chinese unit of length measurement, historically about one-third of a meter.
From Chinese 尺 (chǐ), an ancient measurement unit used across East Asia for thousands of years, representing the distance from elbow to fingertip on average human proportions.
The chih is fascinating because it's defined by human body proportions—many ancient measurement systems worldwide use body parts (cubit, pace, hand), creating a surprisingly consistent global pattern in how humans originally quantified space.
