pocket Inch<->mm converter

[Christophe Mineau]

Hi,
A little hack to make a pocket Inch <-> mm converter : re-use a currency converter calculator

I don't know for the US, but in Europe, it is easy to find some cheap little pocket currency calculators that convert Euro in any currency. You can program the exchange rate of course.

So in this article, I show how I modified one to obtain an efficient Imperial/metric converter (mm <-> Inch) :
La Belle Note - Convert inches into millimeters
In this particular case, efficiency means having the bare minimum of operations to do in order to obtain your result, which is typing you entry number, and hit one single touch, for both directions.

Here is a picture of the converter :


I have programmed the right conversion rate, and I have modified the keys for them to show explicitely "->mm" and "->Inch". See the article.



This is THE tool I really use everyday, it's always beside my computer.

see the next post to see how I addressed the fractional inches issue.

Christophe...
good tip, today metric is a measure that prevailed in the world, but it's always good to have on hand a practice to convert inch to mm form.
Another system found is a smartphone application that also makes this convertible among others.
the page is in Portuguese, but the system is international

Hi Hotz, thanks for the comment,
Yes, sure, the smartphone is always of help for that also, but there are much more operations !
I am very often doing lots of CAD, making my own plans for luthiery projects, and in the world of luthiery, people (to my disappointment ) very often use imperial measures ! especially you guys in the US
But no problem, I can adapt ...
Cheers

Christophe I'm in Brazil (Metric System) inches let me crazy, especially milesimal... lol.

[Christophe Mineau]

Oh Sorry,
I didn't see you were Brazilian, so we share the concern !

Actually, with my children, I have spent a lot of time trying to help them for their school work explaining how fractions work, and when I see the difficulty they have, I always tell them, they can be happy to be European, and if they were in the US, they would have to understand that better, otherwise they wouldn't be able to measure anything.
I really wonder how this is taught and at what age to US and UK children

On the other hand, when I work the French with them, I tell them they are happy it is their mother tong, because I wonder how foreign people can learn French with so much exceptions to the rules (I shouldn't say that, I wish everyone learns French !)

adeus !

is my dear, are we good men around the world learning differences. But to be honest, love these American guys are not much talk but are brilliant at showing its techniques. But that inch drives me crazy it makes
