Overview
Combining facts from the Wikipedia articles "History of the metre" and "Meridian" yields an earth circumference of around 80000 km.
Input
1) en.wikipedia.org/wiki/Meridian_(geography)
A meridian (or line of longitude) is the half of an imaginary great circle on the Earth's surface
2) en.wikipedia.org/wiki/History_of_the_metre
1⁄10,000,000 part of the quarter of a meridian
Output
From 2:
1 m = 1⁄10,000,000 of the quarter of a meridian
Insert 1:
1 m = 1⁄10,000,000 of the quarter of a (half of an imaginary great circle on the Earth's surface)
Reduce
1 m = 1⁄10,000,000 of 1/4 of 1/2 of imaginary great circle on the Earth's surface 1 m = 1/80,000,000 of imaginary great circle on the Earth's surface
Reformulate
imaginary great circle on the Earth's surface = 80,000,000 m = 80,000 km
Compare with equator
Compare that with:
Equator - Wikipedia, the free encyclopedia en.wikipedia.org/wiki/Equator Wikipedia Other planets and astronomical bodies have equators similarly defined. Earth's equator is about 40,075 kilometres (24,901 mi) long
