    Using an interval of 30 mi (50 km), the length is about 2,100 mi (3,400 km). The coastline paradox states that a coastline does not have a well-defined length. Measurements of the length of a coastline behave like a fractal , being different at different scale intervals (distance between points on the coastline at which measurements are taken).

    As in Greek, the number "ten thousand" is used figuratively in Chinese to mean any "immeasurable" value and this title has never provided a literal distance of 10,000 li (5,000 km or 3,100 mi). The actual length of the modern Great Wall is around 42,000 li (21,000 km or 13,000 mi), over 4 times the name's proverbially "immeasurable" length.
