How to convert mm to fractions:
Step 1. Measure or identify the length in mm for the object of interest.
Step 2. Divide the amount in Step 1 by 25.4 to get the inches in decimal form.
Step 3. Take the decimal portion of the result of Step 2 and multiply it by 16.
The point is to determine the nearest 16th of an inch on a ruler.
For example: 120mm divided by 25.4 equals 4.7244 inches. Multiply the 0.7244 by 16 equals 11.591.
Round this to 12/16 or 3/4. The result therefore is 4-3/4"
1 mm = .03937 inches
