(1 INCH = 25.4 MM EXACTLY)
Read from left to right – pick your fraction, decimal, or mm measurement.
Example = convert 1/64″ to mm. Find 1/64 and read to the right under mm!
You will see 0.3969 under the mm column.
Another example = convert 0.125 decimal to inches. Look down the decimal column

MORE USEFUL CONVERSIONS
To convert decimal fractions of an inch to fractions of an inch.
Take the decimal fraction of feet and divide by 0.08333 (1/12th) and this will give you inches and decimals of an inch.
For example – 6.37 feet. Take the 0.37 feet and divide by 0.0833 = 4.44 inches .
So for 6.37 ft. we can also say 6 ft. – 4.44 in.
Now take the 0.44 in. and round it down to 0.4 which is 4/10″
We can now say 6.37′ approximatly equals 6′ – 4 4/10″
For fractions of an inch other than tenth’s, take the decimal remainder of inches and divide by:
0.125 for the number of eighth’s
0.0625 for the number of sixteenth’s
0.03125 for the number of thirty-second’s
0.015625 for the number of sixty-fourth’s, and so on.
For example – 4.382 inches. For eighth’s, divide the remainder, 0.382 by 0.125 and the answer is 3.056 so the fraction is a bit over 3 eighth’s, therefore the answer ends up as approx. 4 3/8″
