Armour ratings
 

I was looking through the help file in MOBHACK trying to figure out how the armour points for the tanks is established. Are the points shown, the thickness of the armour of the real tank in millimeters like in WW2? For example, the Tiger had 100mm of front armour, so in the game it shows 100 front. Or is it devised some other way?

It displays armor in LOS thickness in centimeters.

The Tiger has 100mm of armor at 0 degrees, so it has a 10 armor rating.

Ok, thanks. So an APC with an armour rating of 1 has 1 centimeter of armour or 10mm.

Sloping is also factored in for the armor rating. So a T34 with hull front armor 9 will have considerably less than 90mm of armor plate, but it's slope will give it equivalent of about 90mm protection at 0 degrees.
There's a formula out there somewhere on the boards which shows how slope is factored in (standard mathematics afaik). Haven't got it myself.

There's a simple penetration calculator at this location, but this is primarily for determining armor penetration at two periodic ranges and one slope angle in degrees. This can be used in reverse to determine armor thickness, say by plugging in a number for penetration at a given slope and reducing the sample armor penetration until the armor at vertical equals the SPMBT stat for the armor. At that point, the sample armor thickness should equal the actual armor thickness sans slope. For example, say you're trying to find actual thickness of SPMBT armor value 9 at 30 degrees from vertical. Plug in 9 for Penetration, 30 for Angle, and you should get 11. Now reduce the 9 for Penetration in increments until the 11 result becomes a 9. I got 7 for Penetration equals 9 result. This translates to 7 units of armor thickness sloped at 30 degrees from vertical equals 9 units of vertical armor equivalent. To be more exact, 7.25 units at 30deg equals 9.00 units vertical. I don't vouch for the calculator's accuracy, especially at high angles of slope or longer range; and the method is a bit crude, but it comes pretty close without manually applying Pythagorean Theorem (3-4-5 triangle would only give thickness at 30 or 60 degrees slope anyway, and doesn't take penetration dynamics into consideration...wonder if the calculator does?). Note, this calculator works offline, so you can use a saved copy of the page.

Holy cow, too much work for me! Thanks guys, appreciate it.

If you are into the "do it by yourself" the formula for LOS thickness is: plate thickness/cosine of the angle (or the sine, depending on the convention you are following for measuring sloped armor).
Some examples:
1) T-34 glacis: 4.5cm/0.5 = 9cm = SPMBT value 9
2) T-62 glacis: 10.2cm/0.5 = 20.4cm = SPMBT value 20
3) Jagdpanther front superstructure: 8cm/0.57 = 14.04cm = SPMBT value = 14
