Full Answer

One meter is about the length of a guitar and the width of a doorway. The French Academy of Sciences first defined the meter in 1791 as one-ten-millionth the length of Earth's meridian along a quadrant. The first prototype was 0.2 millimeters short due to a miscalculation caused by the rotation of Earth.
