How to convert decimal inches to inches?

Here’s how you can do it manually:

Understand the Decimal Value: Let’s say you have a decimal value like 6.25 inches.

Split the Decimal: Separate the whole number part (before the decimal point) from the fractional part (after the decimal point). In our example, 6 is the whole number part, and 0.25 is the fractional part.

Convert the Fractional Part to Inches: To convert the fractional part to inches, divide it by 0.0625 (since there are 16 divisions in an inch, and 1 divided by 16 equals 0.0625). In this case, 0.25 divided by 0.0625 equals 4. So, 0.25 inches is equivalent to 4 sixteenths of an inch.

Add the Whole Number and Fractional Parts: In our example, 6 inches plus 4 sixteenths of an inch equals 6 and 4/16 inches. Simplify the fraction to its lowest terms, which is 6 and 1/4 inches.

So, 6.25 decimal inches is equal to 6 and 1/4 inches.
