    2/20/2022 Metrology



    The City of Alexandria has set up a taxi meter course on Eisenhower Avenue with signs that run from 0 - 6 every 1/6 of a mile to measure the proper calibration of taxi meters. Taxi meters are calibrated in 1/6 mile increments.

    See this article in the Washington Post from 5/25/2013

    Very precise measurement here. A metrologist should be proud.

    The Zero Milestone, located on the Ellipse in front of the White House, is a zero mile marker monument intended as the initial milestone from which all road distances in the United States should be measured when it was built.

    How come I never noticed that?
    I'm excited to check that out and also do a fossil bike tour of DC with the resources posted from yesterday!

    I wonder how accurate these measurements are and if anyone was tempted to add a kilometers conversion.
