The dönüm of 919.3 m² is no longer in use. The Iraqi dunam still is, if I read it right, but this would be a good time to abolish it. What they use in Northern Cyprus is moot, as most countries don't recognize it as a separate country. What I propose is that the dunam of 1000 m² be added to one of the lists of units, with all its prefixed multiples. Thus an area of 86000 mm² can be expressed as 86 microdunams. A dunam-meter is a megaliter, and a milliliter of rain on a dunam of land is a kiloliter of water. The corresponding calculations with hectares result in 10 ML and 10 kL, which adds cognitive complication just as using centimeters does. I'm also going to propose that some name (such as "coat") be given to the kelvin square meter per watt. One tenth of this is called a tog, but the use of this unit causes the same problem that the centimeter does. phma
