`  ==Electrical properties/Ultrapure== I fully appreciate the edits to correct my atroicous ) spelling and formatting to a recent edit I made but I do think one part should remain the same. The sectin in question was changed to:  ``It is known that the theoretical maximum electrical resistivity for water is approximately 182 kilohm-meters at 25 degrees Celsius. This figure agrees well with what is typically seen on reverse osmosis, ultrafiltered and deionized ultrapure water systems used for instance, in semiconductor manufacturing plants. A salt or acid contaminant level exceeding that of even 100 parts per trillion (ppt) in ultrapure water will begin to noticably raise its conductivity level by up to several hundred kilosiemens per meter.``  Now, I know wikipedia must conform to standards, a policy which I am an ardent advocate of, and the meter is the SI unit of length as is the kilohm. However, ultrapure water is never, ever referred to using these units. It is always referred to as being 18.2 megohm-cm and has in fact been so often used with these terms that it has bcome synonymous with them and is often simply called ``megohm water`` in the literature. So I'd like to change this back in the article...... `
