The metre was originally intended to be one ten-millionth of the distance from the equator to the north pole running through Paris (making the distance from the equator to the north pole 10,000 km and the circumference of the earth 40,000 km [round that great circle]).
It has since been redefined

In the eighteenth century, there were two favoured approaches to the definition of the meter. One approach suggested that the metre be defined as the length of a 'seconds pendulum' (pendulum with a half-period of one second). Another suggestion was defining the metre as one ten-millionth of the length of the Earth's meridian along a quadrant (the distance from the Equator to the North Pole).In 1791, the French Academy of Sciences selected the latter definition (the one related to Earth's meridian) over the former (the one with the pendulum) because the force of gravity varies slightly over the surface of the Earth's surface, which affects the period of a pendulum.

In the 18th century it was felt that a standard unit of length was needed. The French Academy of Sciences decided in 1791 that the meter would be defined by the dimensions of the planet earth. The metre would be a unit of length such that Earth's meridian line (a line linking the equator with the north pole) was equal to ten million meters. Over the following years measurements of the meridian line that passes through Paris were attempted, so that a standard meter could be cast in metal.
The meter was invented in 1791. As being 1/10,000,000 of the distance from the North Pole to the equator.

To measure the length, height, or width of something that has physical dimensions. Frequently the meter stick has a length of 1m. Gabriel Mouton, the vicar of St. Paul's Church in Lyon, France, is considered by many as the "founding father" of the metric system. It was originally made of titanium.
The origins of the meter go back to at least the 18th century. At that time, there were two competing approaches to the definition of a standard unit of length. Some suggested defining the meter as the length of a pendulum having a half-period of one second; others suggested defining the meter as one ten-millionth of the length of the earth's meridian along a quadrant (one fourth the circumference of the earth). In 1791, soon after the French Revolution, the French Academy of Sciences chose the meridian definition over the pendulum definition because the force of gravity varies slightly over the surface of the earth, affecting the period of the pendulum.
It was established in 1791.

It was originally determined to be 1/10,000,000 of the distance from the equator to the north or south pole. That's why it is easy to remember that the circumference of the earth is 40,000,000 meters, or 40,000 km.
1791 was in the 18th Century.
