for starters \"Currently the meter is the distance light travels in a vacuum in 1/299 792 458 second\" such research was made in the metric system, the distances in \"our\" (I\'m from denmark, metric system is used in most countries in the world) system and therefore it will always be the more accurate.. I can point out several other research materials suggesting the accuracy of the metric system...
\"inch, foot, yard
rod, chain, furlong, mile\"
british names are old, and inaccurate in the manner of being defined as \"parts of a meter, or other metrical units\"
of course the metric system is newer, but it wasn\'t defined on the basis of the other units...
to go completely out of topic, you actually have no units in ligh, electricity and magnetism.. You use the metric system. therefore \"your\" system is out of date and inaccurate... if my use of \"inaccurate\" is wrong please correct me, but what I meant was simply that the metric system is betterm and more precise in the manner that it was not based on something else, but made entirely by complicated research, such as:
The second is determined to an uncertainty, U = 1 part in 1014 by the Cesium clock. The General Conference made the iodine stabilized Helium-Neon laser a recommended radiation for realizing the meter at this time. The wavelength of this laser is
λHeNe = 632.99139822 nm
with an estimated relative standard uncertainty (U) of ? 2.5 x 10?11....
these are the current calculations, but since the system is always being revised, and recalculated, it will become ever more accurate over time...
