The metric conversion between inches and millimeters:

1 inch =25.4 millimetres (a little English lingo for those AC fans out there)I usually just divide by 25,or multiply by 4,and move the decimal point two places to the left.

EXAMPLE:325.0x4=1300.0 Move the decimal point two places to the left,and you have 13.00 inches approximately. If you choose to divide by 25,you also get 13 inches.

An easy way to remember the "25" rule:
Most tire heights for the Cobra are in 25 inch(+or-) range.
