Coin cell nomenclature

In a recent interchange with Rick Sparber I mentioned intelligent nomenclature systems. My wife asked me if I had a 2430 lithium coin cell for her alarm clock. I didn't but in searching around I discovered that those coin cell numbers have meaning.

The first two digits are the diameter in millimeters and the last two digits are the thickness * 10 in millimeters. Thus a 2032 is two centimeters in diameter and 3.2 millimeters thick.

Maybe this is common knowledge among the electrocicers but somehow I never ran across it before.
