Dear Stumped,

I have just read and enjoyed your Q&A, Who will be the first metric president? at: http://blog.washingtonpost.com/stumped/2007/12/ who_will_be_the_first_metric_president.html that was passed on to me by a friend in the USA.

Another question and answer might go like this:

Dear Stumped,

How many people in the USA use the metric system right now — today?

When I visited the USA earlier this year I was stunned to find how many people already used the metric system every day. This was especially true in the automotive, computing, electrical, and manufacturing industries and in the professions such as medicine, optometry, and generally in science. I returned home to Geelong in Australia thinking that about 75 % or more of the people in the USA use the metric system in their daily work.

P.S. It occurred to me to ask you this question after I read your answer to Dave Hecock's question, Who will be the first metric President?

Dear Pat,

The answer to this question is a little difficult because many people in the USA do not want to know the answer to your question — at all!

The answer to, How many people in the USA use the metric system now? is all of us.

That's right, every citizen of the USA uses the metric system every day of their lives for everything they do. This is because measures like feet and inches have all been defined in terms of the metric system since the Mendenhall Order of 1893 and this was upgraded in 1959. The USA has had two feet (ha ha) since the yard was redefined from the 1893 yard (3600/3937 metres) to the 1959 yard of exactly 0.9144 metres. But both the old yard (with its feet and inches) and the new yard (with its feet and inches) — that we use in the USA every day — are both metric yards by the definitions set by the National Institute of Standards and Technology (NIST) in Washington DC.

Every time anyone uses an inch in the USA they are really measuring a 'metric' inch of 25.4 millimetres (exactly) and every time they buy a pound of anything they are measured against a 'metric' pound of 453.592 37 grams (exactly).

If you are not sure how much you use the metric system every day download a copy of the article, Don't use metric from http:// www.metricationmatters.com/docs/DontUseMetric.pdf
