Anyway the distance from Equator to N.Pole is 10,000 KM
FWIW, that definition of a meter hasn't been used since the 19th century. It's currently defined as length of the path travelled by light in vacuum in a time interval of 1/299,792,458 of a second.
Under the modern definition, the Earth is 40,007.86 km in circumference, measured through the poles.
I was explaining its origin since 1/299,792,458 of a second. would be ,otherwise, a completely arbitary number. Also the distance from the equator to the south pole HENCE I used the distance to the North pole
