Line 6: − − It's use is heavily advocated by liberals, who claim that it is more rational. According to conservative political commentator [[Ann Coulter]], "...an inch is the width of a man's thumb, a foot the length of his foot, a yard the length of his belt. That's easy to visualize. How do you visualize 147.2 centimeters?".<ref>Many American [[public schools]] have also begun brainwashing students in this regard to believe that the metric system is "better".

Knock it off! Metric isn't hard. The example is 1.47 meters, or about 1-1/2 yards, or "yay long" (holds out arms). I'll bet even Ann knows that.
In international scientific usage, the ''Convention du Mètre'' is superseded by the conventions of the [[International System of Units]]. However, many of the conventions of the metric system survive, including definitions of units that are not, strictly speaking, SI.

According to [[CIA]]'s World Factbook<ref>[https://www.cia.gov/library/publications/the-world-factbook/appendix/appendix-g.html CIA World Factbook, Appendix G]</ref>, the SI system has been officially adopted in all countries of the world, with an exception of [[Burma]], [[Liberia]] and [[the United States of America]].

The inertia of the United States, unfortunate though it may be, is rooted in an enormous amount of existing industrial equipment and usage. Companies that do any international business have to do a lot of conversion work in order to make their products compatible with the rest of the world. This is slowly leading to more widespread adoption of the SI system in the United States, but progress is very slow.
Some space missions have failed because of unit incompatibility in guidance software between US and SI measurements.
