As a Christian I have to go with the inch. It is far more accurate than the man made metric system. Read on if you want Preachy but hey thats were we got the inch.The pyramid is the finest example of the Accuracy of the inch. Excerpts below. please, if this offends, then dont read it. Thanks.
THE EARTH'S POLAR DIAMETER
After these somewhat extended introductory remarks our appreciation of the modern science of the Great Pyramid should be quite keen. According to the International Spheroid of Reference adopted in 1524, the polar diameter of the earth is 7,900 miles. This is the finding of modern seience and represents an achievement not possible until recent years. The Pyramid inch, measuring just .0011 more than the English inch - 10,011 equalling 10,000 Pyramid inches - and indicated by the "Boss" on the Granite Leaf in the Ante Chamber, is very definitely stated in the "Book of the Dead" to be exactly 1/500,000,000 (one five hundred millionth) of this diameter. A simple calculation will show that 500,000,000 such inches represent, Within 100 feet, the accepted diameter of 7,900 miles. The Pyramid or English inch is, therefore, both a divine and scientific unit of measure.
THE METRIC INCH NOT SCIENTIFIC
In this connection it will be of interest to examine the metric inch. This unit of measure is of atheistic origin, having been introduced by the French sceptics during the Reign of Terror in 1790. Rejecting everything which savoured of the divine, they estimated the length of a quadrant of the earth's circumference along the meridian passing through Paris. This they divided by 10,000,000 and so obtained the unit of measure known as the metre or 89.371 English inches. NOW concerning this product of atheistic scientists, we need not be surprised to learn that it harmonizes quite well with their frightful and tragic administration of French affairs. As a unit of measure it represents an error of 100,000 inches in its estimate of the polar diameter, and memorializes a scientific blunder in ordinary mathematics of one metre in every 5,300. It therefore has really no scientific value whatsoever. Sir John Herschel pronounced it the "newest and worst measure in the world," while another man of science regarded it as "inconvenient, inaccurate and unstridable." For tone thing is it to be commended - it symbolizes the falsity, confusion and spiritual destructiveness of atheism.

In an appendix to Peter Tompkin's popular book, The Secrets of the Great Pyramid, is an appendix about ancient Egyptian measures. People can marvel at how "advanced" this system of measures is. But the very concept of "advancement" implies that the roots of the Egyptian science were gleaned from former "lower" civilizations which were before the Egyptian. But that is simply not the case. The Bible makes it abundantly plain that Noah's son Ham was the father of Egypt.1 Noah was the recipient of the advanced knowledge that had come into the world through revelation to the patriarchs before him, especially through Enoch and Adam. Noah used much of this advanced knowledge in construction of the ark, which he built according to the divinely ordained cubit, the basis of the ark's design.2 The cubit is mentioned also in the book of Revelation:
(Rev 21:17) And he measured the wall thereof, an hundred and forty and four cubits, according to the measure of a man, that is, of the angel.
It is mentioned as the unit used by angels. The cubit is a measurement standard from out of this world, used by angels in Heaven. How interesting that the cubit shows itself to be a more rational and scientifically accurate standard than the metric system! When the French savants who invented the metric system chose a standard for that system, they took the one ten millionth part of a meridian from the North Pole to the equator through--where else?--Paris. Ta da! The meter is born...
The problem with this is not only that the meridian through Paris3 is different than all other meridians, but is also subject to change as the topography changes. On the other hand, the sacred cubit is the one ten millionth part of the earth's semi-polar axis, a radius from the center of the earth to the North Pole. This semi-axis does not vary as would a meridian, whether through Greenwich or Paris. If the ancient Egyptians designed the cubit based on the earth's semi-polar axis, and the French scientists--cream of the crop of the Age of Enlightenment, the flower of modernity--did so based on a Parisienne meridian, one has to wonder if evolution is running in reverse. Of course it is more likely that the Creator is the One who designed the cubit to be in direct relation to the planet for which it was meant to be a standard.
The Bible says in eight different places that the Ten Commandments --God's moral standard, just as the cubit (and its corresponding inch) is a linear standard-- were written with "the finger of God," not the genius of Moses. It is a distinctly modern idea that humans can make their own standards, whether moral or linear. This is certainly the prevailing ethic in the schoolroom today. Students take it as an a priori, unquestionable law of the universe that truth is what each individual perceives it to be. Alan Bloom tells us that almost every one of his college students believes this.4 This would have been unthinkable in ancient Egypt.
