Thickness

[merlin]

Some help please....Am wanting to use brass and copper in some pens...I have aluminium from a coke can and hat measures at 0.005mm.

Online the sizes confess me,  never any good with maths and fractions and........... 

Is 0.005mm the same as 0.05mm

Cheers Merlin...............

.005mm is 5 thousands

.05mm is 5 hundreds. or 10 times larger

Are you sure? A human hair is about 0.0035 inches". Most aluminum foil is about 0.005 inches". Go here for an inch to millimeter chart .http://www.hotwatt.com/inchto.htm    0005mm is incredibly small, much smaller than a human hair. Are you certain that you need something that small? It will almost be transparent.

I don't know why we haven't switched to the metric system.

We have.  As long as you want to buy soft drinks (2 liter bottle), or take some ibuprofen (200mg pills)

I will have to agree with that.

They tried, at least once - I remember when they did - well, can't remember exactly when - think when I was in school but can't recall exactly how old I was -  but Americans being Americans we pushed back and said - NOT.   You might remember, its when they tried to put the road signs up with both distances trying to "convert" us slowly.  Didn't work though so I think they gave it up. (One reason I gather was it was not "mandatory" but "voluntary."

Edited to add: went looking to see "when" we tried to make the Country change to metric - I was right in was in my childhood/school years.

"In 1975, Congress passed the Metric Conversion Act, which declared metric as the preferred system of the United States, and the U.S. Metric Board was created to implement the conversion. . . . (found another article that says that Board was abolished in 1982 by President Regan.)

America began testing road signs in kilometers under President Jimmy Carter,. . ."  found in this article (among some others I found: http://www.cnn.com/interactive/2015/07/us/metric-road-american-story/ and this one that explains why we didn't go with Metric way back when in our founding years: http://time.com/3633514/why-wont-america-go-metric/  (several others said the same thing) which says in part:

"The measurement debate actually goes back to our nation’s very beginning. The original metric system was developed in France during its revolution, and was so radically decimal that it divided the day into 10 hours. As our first secretary of state, Thomas Jefferson was charged with deciding which set of measures would be best for the country. He had been instrumental in creating the dollar—the first fully decimal measure any nation ever used. Jefferson rejected the metric system, however, because in origin he found it to be too French. . ."

However, other things in those and other articles noted that many things we buy now list the metric volume or sizes so that we are "partially" there.

Melaine I remember that also. It would have been hearder then than now but if we had switched it would have been over by now.

I don't know.  I've gotten along for 57 years just fine without it and I hope to live another 20 or 30 never having to adapt to it.
