The world has chosen the metric system as standard. The U.S. wants to stick to the retarded English system because they're cool that way. Plus the terrorists use the metric system , are you with Us or are you with the terrorists?
In Lebanon we've replaced rulers, odometers, and GPS systems with a God given measuring tool. It is a standard everyone can relate to. No one can visualize what 17 centimeters might look like, but even a blind man (or woman) can feel a shibr. There are no centishibrs or nanoshibrs and all the confusing scientific mumbo jumbo. The shibr is only divisible in half.
Some might argue the Shibr has limitations.
Here's proof that adopting the Shibr as your measuring standard does not stop you from building high rises, but rather saves you machinery and manpower. I do suspect however that there was a Lebanese architect on the lose in Tuscany using the Shibr sometime in the 13th century.
My favorite use of shibr is a linguistic one used to further belittle a little person. This is demonstrated in the following statement:
"هيدا واحد زمكّ, ما بيطلع طولو شبر ونص"
"This a zmeck, his height is not even a Shibr and a half."
The Shibr; another handful of tradition from Lebanon.
