Converting decimal feet to feet and inches is a common task in various fields such as construction, carpentry, and engineering. To perform this conversion, first separate the whole number from the decimal fraction. The whole number represents the feet. Then, multiply the decimal fraction by 12 to convert it into inches. For example, to convert 5.75 feet: the whole number 5 indicates 5 feet, and the decimal .75 multiplied by 12 equals 9, so the measurement is 5 feet 9 inches. This method ensures precise measurements, which are crucial for accuracy in various applications.
