Well, that was a certain fraction of the distance from the north to the south poles along a particular line of longitude. I forget both the fraction and the line of longitude. The modern meter is the wavelength of a certain color of light emitted from the most common isotope of tungsten heated to a particular temperature. Nice, handy references. But, for those stuck on the English system of measurement, we just need to remember that a meter is 39.37 inches, or a tad more than a yard.
Got your rods and furlongs straight? How about cups and bushels? I like the metric system myself.
