A metre (US spelling, meter ) is the basic unit of length in the SI measurement system. The symbol for the metre is m . The first meaning (in the French Revolution ) was one ten-millionth of the distance between the Earth 's equator and the North Pole along the Paris meridian . ^[1] The metre is now defined as the distance light travels in a vacuum in 1/299,792,458 of a second . ^[1]

In the imperial system of measurement, one yard is 0.9144 metres (after international agreement in 1959), so a metre is very near to 39.37 inches : about 3.281 feet , or 1.0936 yards .
