1 inch = 25.4 mm
1 mm = 0.0394 in
so 18 mm = 18 X 0.0394 in = 0.71 of an inch (just over 7 tenths of an inch)
And since decimal inch rulers aren't readily available, you'll have to convert to fractional 16ths:
Multiply 0.71 x 16 to get the number of 16ths inch.
0.71 x 16 = 11.36
11.36 = the number of 16th's of an inch. This is the numerator of the fraction. Apply the rules for rounding.
11.36 rounds to 11 because 0.36 is less than 0.5
Therefore, 0.71 in. = (approximately) 11/16ths of an inch
