 DC> decimal point is rarely used verbally.  But, a 45 caliber
 DC> pistol is actually .45 caliber.

 JB> I realize that. The answer actually came out to .3545
 
No, that's just different measurements for the basic concept.  

 DC> If you divide inches by inches you get pure numbers.  IOW, 2in/1in = 2
 DC> , 2 only.  It does not equal 2 caliber nor even 200 caliber for that
 DC> matter.  As I wrote, "caliber" is only the description of what is
 DC>  being measured.  It is not a measurement of size of any type.  Even
 DC>  in large guns on battleships, it's a pure number ratio.

 JB> I'll look into a little more. I think you or whoever was right the
 JB> first time. A caliber is the diameter of the bore of a gun in inches.

But, it doesn't have to be in inches.  Any unit of length would 
do, including furlongs.  However, mm and inches happen to be a lot 
more convenient to use and visualize.  

 JB> So, all I'm asking is to convert mm's to inches so the metric
 JB> measurement can be expressed as caliber.

1 in = 25.4 mm  

.35 cal to mm

do it this way:  

.35 in  x 25.4 mm
-----------------   
     1 in 


the "in" cancel out and you are left with 

.35  x 25.4 mm
-----------------   or more simply   .35 x 25.4mm  wich eqauls 8.89mm
     1 


 
 DC>> The caliber of a 9mm pistol is (what else?) 9mm
 JB> See what I mean?  Your statement here is missing my question above.

 DC> Calibers are not really a measurement as such.  It is a description
 DC> of what is being measured, ng the diameter of the bore of the gun
 DC> barrel.  The units measuring can be any unit of length.  Like it or
 DC> not, my use of 9mm as the caliber of a gun is 100%.

 JB> I don't think so.  Caliber is a measurement expressed in inches. It's

Nope, caliber is only the description of what is being measured.  
A caliber has no length, diameter or anything,  It is simply the 
fact that there is a hole in the center of the axial shaft of 
an elongated object.  

 JB> the diameter of the bore of a gun (a measurement). If it can be
 JB> expressed in inches, it definitely can be expressed in mm but must be
 JB> converted from inches to mm's.

Nope again.  It can be bored in mm just as easily as it can in inches or 
fractions of a light year.  
 
 DC> Would you care to bet on it?  How much do you want to lose?

 JB> I don't want to bet, 

Good move!  

 JB> I'm just curious.

You'll get there once you realize that caliber does not have 
a stated size.  It is a concept describing what is being measured.  

Try this:  How big is a hard drive?  

If you are talking dimensions, most hard drives today are pretty 
much the same in size for desktops.  

Now, how about capacity? 

Equate "platters" to "caliber".

If I gave you one of 2 identically sized HDs how would you know one is 
is bigger?  

Every HD has at least one platter and a set of heads.  Most have more.  
Yet, the cases they come in are often the exact same size, especially 
if the mfg is the same.  

In general, a HD with 2 platters would be twice as large as one 
with 1 platter.  You determine that by measuring, ng counting, 
the platters.  

Now, back to guns:  To determine which gun is deadlier (again, 
in general) you count, in this case measure, the diameter 
of the bore.  The larger the bore the deadlier the gun.  

If the above doesn't work for you, well use what a medical dose is...
