This is the inches to fractions calculator, a simple and intuitive tool that helps you convert any decimal to fraction inches. Do you want to transform the length measured in mm to inches fraction? That's not a problem at all! Alternatively, you can also turn any fraction to inches, and then to its inch fraction, adjusting for the appropriate precision. Converting inches to fractions has never been this entertaining, has it?
How to convert decimal to fraction inches?
Transforming a distance in its decimal form to its fraction inches is almost the same as converting any decimal to a regular fraction. Almost. Principally, we have to find the ratio of two numbers, the numerator and the denominator. The only difference is that the denominator should be to the power of 2: 2, 4, 8, 16, etc.
So, how to convert decimal to inch fraction?
- Let's take your decimal value,
- Choose the precision, or in other words, the value of denominator,
- Multiply these numbers and round them to the closest whole number,
n = round(d*x)
- The resulting inch fraction is then
As you can see, the outcome is sometimes only an approximation of real value because of rounding. But for typical everyday measurements, it's accurate enough, especially when you choose a precision of
1/32 or higher.
How to convert distance in mm to inches fraction?
Imagine you want to buy new tires for your bike, or you're preparing a spot for your new TV. You take out your ruler or meterstick, and get to measuring. But it's in mm, or cm, or another metric unit your not exactly familiar with. So, is there an easy way to convert mm to inches fraction?
The answer is YES:
If you have the length in mm, divide the result by
If you have the length in cm, divide the result by
If you have the length in m, divide the result by
Then convert this decimal to fraction inches as you've learned from the previous section
You can convert any length unit to inches, but you don't have to remember all the formulas by heart - just use our inches to fraction calculator, and choose one of the most common length units.

Let's convert inches to fraction - inches to fraction calculator in practice
Imagine you've bought a wooden panel, 5 meters long. You plan to cut it into six equal parts, but you have only a tape measure with the fractional inches scale. We can measure the length with precision down to
1/32". Here is how to deal with the problem:
Divide 5 m by 6,
5 m / 6 = 5/6 m. It's the length of each part.
Convert the measurement in mm to inches by dividing the value by 25.4, and rounding the outcome to two decimal digits (those will be our significant figures):
(5/6 m) / 25.4 = 32.81 in.
Our precision is
1/32". Multiply the value above by 32:
32.81 in * 32 = 1049.92 in.
Round the outcome to the nearest whole number,
Finally, we can convert the length from inches to fraction:
As there are countless equivalent fractions to our result, we can make our lives easier by simplifying this inch fraction. Find the least common multiple of 1050 and 32, which is 2. Divide both numerator and denominator by 2, so we get
525/16". As it's an improper fraction, convert it to a mixed number:
32 13/16"(you can use the modulo operation to find the quotient quickly). If you want to go even further, let's extract feet from the result of the mm to inches fraction conversion. The result is finally:
2' 8 13/16"
As you can see, there are a few steps you should take to obtain the outcome. You can save time by using our inches to fractions calculator, as it shows the result immediately!
