Metric vs. Imperial Match

3D Design Volume Model

Hello

Does anyone have a nice table that allows you to make the measurements of the side bearings in inch correspond to the caliper, and: 

the standard inch and then the correspondence in metric.

 

For the moment I have this:

Smooth hole Ø0.41 = 13/32 DRILL

Tapping 0.38 = (.312) DRILL THRU, 3/8-16 TAP THRU

Smooth Hole Ø31 = (.312) DRILL THRU

Thread 0.31 Outlet = (.257) DRILL THRU, 5/16-18 TAP THRU

Smooth hole Ø 0.28 = (.281) DRILL THRU

Thread 0.25 through  = (.201) DRILL THRU, 1/4-20 TAP THRU

Thread 0.25 non-penetrating = (.201) DRILL x 5/8" DP, 1/4-20 TAP x 1/2" DP

 = (.149) DRILL THRU, 10-24 TAP THRU

 

I'm a bit lost in solidworks in my tapping, my holes, etc... with the 1/4 3/8 #7 0.219 etc...

 

I accept the maternal shorts on the imperial measurements lol

Hello

 

You select your dimension in inch for example you go to "other" "Modify units" and there you put in millimeters or others

 

See .jpeg attached.

Thank you@gt22 ;)

it will help to convert,  but it's the #x that will get me into trouble with the A B C D E etc... (Drilling in Solidworks)

 

@georgesm

It's well before the drawing my problem.... after that, it's easy, we convert units in the options

 

I even created the model parts in inch, in mm and one in double side with all the properties

I think you don't know these very useful products I find:

 

Tolerator

filetor

Convertor

Here is the site that comes close to what I am looking for fractions

http://www.hamuniverse.com/antfrac.html

 we still have to find the drilling values #1 #2 #3 .... #99 and the drilling sizes for the letters A, B, C, D ...... which must correspond to tolerances.

Here's what I was looking for.... There's an app for that!!!
