I still prefer Metric, but, I have a very good sense of what an acre, 10 acres, and 640 acres are (I have family that farms, and a "section (640 acres)" is a pretty common unit of measurement.

57,910 acre feet would actually be more "intuitive" to me than 70,000 cubic meters (though much harder for me to do calculations and almost impossible to do unit shifting).

57,910 acre feet is roughly 100' deep of water on a section of land. I can "visualize" what that reservoir would would like.

Or, for more practical/relevant to irrigation purposes, it's 100 sections of land, 1' deep.

But yes, I'm still going to argue for the metric system. I promise.
