Only a couple years after this 1961 letter claiming metric=communist plot to destroy America, Stanford made this prediction:



The Stanford Research Institute predicts that the U.S. will have changed over to the METRIC SYSTEM by 2000 A.D. The change, long advocated by engineers & scientists, will be delayed that long by both the expense involved & public resistance to giving up inches, feet, ounces & quarts. The cost of retooling & conversion of inventory & account records in the automotive industry alone would be about $700 million.
