If the units of length are powers of 1000, then the square units of area are also powers of 1000 (in fact powers of 1,000,000). I know of two units of area that are, though rational, not square: the acre, which is 66²*10 square feet, and the dunam, which is 1000 square meters. Both are 10 times a square, or equivalently 1000 times a square. Pierre -- sei do'anai mi'a djuno puze'e noroi nalselganse srera
