How to convert decimal fractions to measurements?

In construction, it's common to use decimal fractions to represent measurements. For example, a contractor may need to cut a board that is 2.75 feet long. To make the cut, they need to know how many inches to measure from the end of the board.
To convert a decimal fraction to inches, you need to multiply the decimal by 12, since there are 12 inches in a foot. Let's use the example of a board that is 2.75 feet long:
2.75 feet = 2.75 x 12 inches = 33 inches
So the contractor would need to measure 33 inches from the end of the board to make the cut.
Another example: let's say you're building a wall and you need to know how long each stud needs to be. The blueprint specifies that the studs should be 16.5 inches apart. To calculate the length of the studs, you would multiply the number of spaces between them by the width of each space:
16.5 inches x 2 = 33 inches
So the studs should be cut to a length of 33 inches.

To convert a decimal to a fraction in inches, you can follow these steps:
  • Determine the denominator: The denominator of the fraction will depend on the smallest unit of measurement you want to use. For example, if you want to use 1/16 inch as the smallest unit, then the denominator would be 16.
  • Convert the decimal to a fraction: To convert the decimal to a fraction, you can multiply it by the denominator you chose in step 1. Round the result to the nearest whole number, then write it as the numerator of the fraction.
  • Write the fraction: Write the numerator you obtained in step 2 over the denominator you chose in step 1.
  • For example, let's say you have a decimal measurement of 0.375 inches, and you want to convert it to a fraction using 1/16 inch as the smallest unit.
  • The denominator is 16, since we are using 1/16 inch as the smallest unit.
  • Multiply 0.375 by 16: 0.375 x 16 = 6. Round 6 to the nearest whole number, which is also 6.
  • Write the fraction: The fraction is 6/16, which can be simplified to 3/8. So 0.375 inches is equivalent to 3/8 inch.
  • To convert a distance in mm to inches and fractions, you can follow a similar process:
  • Determine the denominator: The denominator of the fraction will depend on the smallest unit of measurement you want to use in inches. For example, if you want to use 1/16 inch as the smallest unit, then the denominator would be 16.
  • Convert the mm measurement to inches: To convert the mm measurement to inches, divide the mm measurement by 25.4, since there are 25.4 mm in one inch.
  • Convert the decimal to a fraction: Follow the steps outlined above to convert the decimal to a fraction in inches.
  • For example, let's say you have a distance of 50 mm, and you want to convert it to inches using 1/16 inch as the smallest unit.
  • The denominator is 16, since we are using 1/16 inch as the smallest unit.
  • Convert 50 mm to inches: 50 mm / 25.4 = 1.969 inches.
  • Convert 1.969 inches to a fraction using the process outlined above. The result is 1 15/16 inches.
