I think the hectare ought to be scrapped. If any unit of area should have a special name, it's the dunam, or stremma, which is 1000 m²*, which follows the rule of 1000. A gigadunam is a square megameter. Neither the gigare nor the megare is the square of any named unit. This would give a name to the unit midway between the square kilometer and the square megameter. Lake Superior is 82.4 megadunams. A hectare-millimeter is 10 m³, which isn't the cube of anything rational, nor does it have a unit name. A dunam-millimeter is a cubic meter, which is a kiloliter. For people who think in powers of 1000, the latter is easier. *Except in Iraq, but the Iraqis should abolish their own special dunam and use the same one as their neighbors. Pierre
