The formula in plain language
Add every length after converting it to a single unit, then show the total in feet and inches snapped to the nearest sixteenth. An inch is exactly 25.4 millimeters. A foot is 12 inches. The expression can mix feet, inches, fractions, centimeters, and millimeters, and it can subtract with a minus sign.
A worked example
6 feet 8 5/16 inches, plus 12 centimeters, minus 8 inches, plus 2 millimeters, lands on 6 feet 5 1/8 inches.
Feet, inches, square feet, and cubic yards have to be converted before they are multiplied. This feet and inches length result should agree with square footage and an inch fraction.
Mistakes that move the answer
- Write the unit on every term. A bare number is read as inches.
- A sixteenth is the usual construction rounding. Finer fractions still display to the nearest sixteenth.
