Dear Mr. Munroe, Thank you for creating your metric converting guide (http://xkcd.com/526/). From the title, one would think it would be yet another table of conversion factors, but it is hardly that. It is a table of reference points that encourages the user to "think metric." It is also gratifying that you have released this table to the public domain.
The U.S. Metric Association (USMA), Inc., is a non-profit, national organization, founded in 1916, and dedicated to U.S. conversion to the SI metric system as the Nation's everyday standard of measurement. Tables such as yours shall be part of the primary education tools for the process once the U.S. creates a metrication plan. lan For general use, however, I do hope that you will remove from the table that some might deem to be offensive (e.g., the -20 C entry). SI-incerely, Paul Trusten, R.Ph. Public Relations Director U.S. Metric Association, Inc. www.metric.org 3609 Caldera Blvd. Apt. 122 Midland, Texas 79707-2872 US +1(432)528-7724 trus...@grandecom.net
