muku [Hawaiian]

In Hawaii, a unit of length, equal to the distance between the fingers of an outstretched arm and the elbow of the other arm, when it too is outstretched, but bent at the elbow. About 4.5 feet (1.4 meters). Although the muku is not mentioned in the law of 1842 establishing a system of weights and measures based on those of Massachusetts, it does occur in other early laws.

The muku is an unusual, even unique, body measure. Curiously, the stance of a person demonstrating the muku resembles one often struck in hula dancing.
