A board is 7 feet 9 inches long. How long is it in inches

To convert the length of the board from feet and inches to just inches, you start by converting feet to inches. There are 12 inches in a foot, so: 7 feet × 12 inches/foot = 84 inches. Now, add the remaining 9 inches: 84 inches + 9 inches = 93 inches. So, the board is 93 inches long! Did you know that the measurement of a foot has historical roots? The length of a foot was derived from the average size of a human foot! Just imagine the variety in measurements if we still used every person's foot as a standard—everyone would be walking around with different-sized tapes. In practical use, knowing how to convert measurements is super handy! For example, carpenters often have to quickly convert between feet and inches when building furniture or structures. To avoid mistakes, a good tip is to always write down your conversions and double-check your math. Little errors can lead to big problems in your projects—like cutting a board too short!
