Jut got an update on States reversion (or perversion as the case may be) back to English. I'm not sure who produced it. States Still SI as of 5/30/01: Alaska, California, Kansas, Maine, Massachusetts, New Hampshire, New York, Oregon. States still dual as of 5/30/01: Delaware, Louisiana, Vermont, New Jersey, Pennsylvania, Puerto Rico, Washington Seems to me these dual States are headed back to English even though they are not officially SI. The rest either never converted, have reverted or are in the reversion process. The sad part is I counted 22 States that revered by orders of the State DOT or their commissioner. Only three were due to "State Legislature" although I'm sure with the others there was significant political pressure which is not apparent in this listing. Four States are 100% metric based on 1999 % construction (maybe its higher for other SI states by now.) New Jersey (dual), Oregon (SI), New York (SI), Utah (SI but recently announced reversion). Sorry the news is so grim. Howard Ressel, Metric Manager New York State Department of Transportation, Region 4
