Hi.

Searching for inch to metric tables I did not find any that "suited" my "needs".
I decided to make my own as a python programming exercise.
As an engineer I wanted the table to be accurate.
The number of decimal places are whatever is required to get an accurate number -
no round-off errors in this table.
(I can easily "chop off" mentally but I cannot add any "missing digits")

Here are the result as PDF files in both DIN-A4 and US-Letter sizes.

I saved them in my Dropbox on my IPad Air. Thanks For the table Ragnar!
 
If one has an IPAD there are really great conversion apps that do many types of conversions and they are free!
 
This is is awesome, I've been looking for a decent conversion chart for along time.

on another note, I'm trying to learn and get better at using the 32mm, is there a chart out there for 32mm standards and imperial conversion?

[thanks]
 
Here's a link to a very simple 32mm to decimal conversion chart I made to help me do the metric conversion:

It's not as pretty as ragstian's, but I use it all the time.

Edit: Here's the one I was REALLY looking for. Sparktrician posted it that same thread. His is MUCH prettier, and uses fractions rather than decimal inches like mine does.

Thanks Wow,

Dare I ask how you remember everything is so well, I wish I could.......

Cheers
 
Hi

land_kel:
Can't open either attachment. Are they in .pdf format?

Yes they are in PDF format - you can open with Adode Reader or the one I prefer, Foxit Reader.
If you want the attachment in any other format please chime back - I can make PS,  JPG, BMP, SVG (and more) to name a few.

I never realized - until I made this chart - that for every fraction "type" - let's say 16th's and call the type "n"
- there are; 1,3,5,7,9, up to (n-1) parts, eg for 8th's -1,3,5,7. Interesting.

32mm standard is new to me - I will look into it - and make a nice "Festool style" chart/table. Any good info on using the 32mm "system"?
I liked the idea of alternating the background color every other line as in "Sparktrician's" table, back to the drawing board to "prettyfy" mine!

The 'search' function is your friend if you can remember even some of it...

The 32mm cabinet sizing started in Europe after World War II because there was so much housing Reconstruction that had to be done the architects/builders/zoning settled on a standard sizing for residential fixtures and 32mm was good size.

One can make their own tables using Microsoft Excel or OpenOffice.org Calc.

 
Sir Willy - aka Sparktrician - was kind enough to send me his file which I massaged a little to come up with a chart that I really like.

Edit: I forgot to mention that Willy and I added decimal equivalents to his original table since that's easier for some people and makes the chart more complete.

My eyes aren't 21 anymore, so I worked hard to make it more readable. And I think you'll like the color scheme!

Edit #2 - if you go to a FedEx Office (Kinko's) or similar place they can print it at poster size from the PDF and you can hang it on your shop wall!

Why is every third line highlighted?  Normally, it would be every other or every fifth line.

Those are 96mm increments. But I could re-do it to be anything that you wanted?

[size=18pt]
Like Metric only!?  [big grin] [big grin] [big grin] [eek] LOL
[size=14pt]

But to be serious, great work both of you, and shock horror, I will be using it! Love the 32mm increments.
[size=10pt]

Edit. DL to IBook just now, so that side of things works too.
 
Hi.

wow: Very nice indeed - did you work out ALL the fractions manually?
A few typo's that slipped past the "proofreader":
for the 2nd and 3rd multiple of 32, the inch&fraction is listed as 2-17-32 and 3-25-32 instead of 2-17/32 and 3-25/32 as in the rest of the table.

The colors are nice!
Another question from a woodworker-newbie; when would you use the "32 system" and why?

For cabinet making. It is a European standard for cabinets. Since many bookcases are married to cabinets, it would be good to make them with same standard.

As mentioned, after World War II there was a need to quickly build residential housing and the architects and furniture makers agreed on making cabinets as a multiple of 32mm.
