It might sound improbable but it’s true! Origin of the meter Just a few years after the French Revolution of 1789 the French Academy of Sciences defined the meter as 1/10 000 000 of the distance between the North Pole and the Equator. What is the approximate distance around the Earth in km/miles? 10 000 000 m Today over 100 bronze medallions can be seen marking the original line through Paris. 40 000 000 m = 40 000 km 5/8 x 40 000 = 25 000 miles It might sound improbable but it’s true! In 1884 at a conference in Washington and with much French resistance, the Greenwich meridian was adopted as the world’s Prime Meridian. This line of longitude passed through Paris as did the Paris Meridian. cm 10 20 30 40 50 60 70 80 90 100
