A meter is no longer defined as 1/10,000,000 of the distance from the equator to the north pole, it has a definition based on properties of matter and energy that are not sensitive to temperature and not subject to difficult and inherently imprecise geodetic measurements. In fact, a meter is defined as the distance light travels in 1/299,792,458 of a second. The second is defined by a nuclear oscillation in cesium, specifically: "The duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium-133 atom" Other metric system units have similarly objective definitions.
