Inches to feet divides by 12. A 72 in board is 6 ft; a 30 in desk height is 2.5 ft (2 ft 6 in). The whole-number part is the feet; multiply the remainder by 12 to recover the leftover inches. This conversion turns a long inch count — common on cut lists and tape measures — back into the feet-and-inches form used for room dimensions and human height in the US and UK.
Carpenters framing stud walls read a plan dimensioned mostly in feet but individual stud spacing and trim reveals are called out in inches on the same drawing, so switching between the two happens dozens of times a day on site. Standard 16 in on-centre spacing is 1.333 ft, and a framer who mentally rounds that to 1.5 ft ends up short a stud over a long wall run. Keep stud layout in inches throughout the framing stage; only convert to feet for the overall wall length on the material order.
