To convert Thousandths of an Inch to Inch Fractions and vice versa, there are several paths, in this article I share the easiest path.

Part 1. Converting Thousandths of an Inch to Inch Fraction.

Procedure:

1. Count the decimal digits (n) that are after or to the right of the decimal point.
2. Create a multiple of 10 with the previous digits (n) like 10^n.
3. Multiply the value in thousandths of an inch by the multiple of 10 found in step 2, to find the numerator of the fraction.
4. As the denominator, place the multiple of 10 found in step 2.
5. Simplify to the maximum.

Example:

Convert the value 0.46875 to an inch fraction.

Steps:

1. Count the decimal digits (n) that are after or to the right of the decimal point. In this example, to the right of the decimal point in the value there are 5 decimal digits, so n = 5.
2. Create a multiple of 10 with the previous digits (n) like 10^n.
   In this example, as n = 5, we will have a multiple of 10 like this: 10^5 = 10X10X10X10X10 = 100,000
3. Multiply the value in thousandths of an inch by the multiple of 10 found in step 2, to find the numerator of the fraction. So: 0.46875 X 100,000 = 46,875 which is now the numerator of the fraction in inches.
4. As the denominator, place the multiple of 10 found in step 2. So: 46,875/100,000
5. Simplify the previous fraction to the maximum:
   46,875/100,000 ; if you take a fifth (divide by 5) in the numerator and denominator = 9,375/20,000 you can still continue simplifying:
   9,375/20,000 ; if you take a fifth (divide by 5) in the numerator and denominator = 1,875/4,000 you can still continue simplifying:
   1,875/4,000 ; if you take a fifth (divide by 5) in the numerator and denominator = 375/800 you can still continue simplifying:
   375/800 ; if you take a fifth (divide by 5) in the numerator and denominator = 75/160 you can still continue simplifying:
   75/160 ; if you take a fifth (divide by 5) in the numerator and denominator = 15/32 you can’t simplify any further.
   We have reached the end of the simplification or reduction of the fraction, so we have also finished operating, so finally:

We have reached the end of the simplification or reduction of the fraction, so we have also finished operating, so finally:

0.46875 in. is equivalent to 46,875/100,000 and is in turn equivalent to: 15/32 in.

Let’s see another example:

Convert the value 0.875 to an inch fraction.

Steps:

1. Count the number of decimal places (n) that are after or to the right of the decimal point.
   In this example, to the right of the decimal point of the value there are 3 decimal places, so n = 3.
2. Create a multiple of 10 with the previous digits (n) as 10^n.
   In this example, since n = 3, we will have a multiple of 10 as follows: 10^3 = 10X10X10 = 1,000
3. Multiply the value in thousandths of an inch by the multiple of 10 found in step 2 to find the numerator of the fraction.
   Then: 0.875 X 1,000 = 875 which is now the numerator of the fraction in inches.
4. As denominator put the multiple of 10 found in step 2.
   Then: 875/1,000
5. Simplify the previous fraction as much as possible:
   875/1,000; if you take the fifth part (divide by 5) in the numerator and denominator = 175/200 you can still simplify further:
   175/200; if you take the fifth part (divide by 5) in the numerator and denominator = 35/40 you can still simplify further:
   35/40; if you take the fifth part (divide by 5) in the numerator and denominator = 7/8 you can’t simplify any further.

We have reached the end of the simplification or reduction of the fraction, so we have also finished operating, so finally:

0.875 in. is equivalent to 875/1,000 and is in turn equivalent to: 7/8 in.

Part 2. Convert Fractions of an Inch to Thousandths of an Inch.

This case is very simple, just take the numerator of the fraction and divide either by hand or with a normal calculator by the denominator of the fraction.

Example:

Convert to thousandths of an inch the following fraction:

3/4 in.

Then take the numerator 3 and divide it by the denominator 4, the result is: 0.750 in.

When the fraction is a mixed number, that is, when the fraction is accompanied by a whole number, then we only work with the fraction and in the end we add the whole number, like this:

Convert to thousandths of an inch the following fraction: 3 5/16 in.

Then we only work with the fractional number: 5 divided by 16 = 0.3125 and then add the integer of the fraction which is 3, then:

3 + 0.3125 = 3.3125 in.
