Inch = Foot × 12. Every value is converted through a single meter base unit using internationally defined conversion factors, so any from/to pair stays consistent.
Good to know
Converting feet to inches comes up constantly in everyday tasks where measurements are given in whole feet but you need finer detail: cutting lumber, hanging a TV at the right height, ordering carpet or curtains, reading building plans, or logging a person's height for a medical or sports form. Because most US tape measures and rulers are graduated in inches, turning feet into inches is often the last step before you actually mark, cut, or compare.
Both units belong to the imperial and US customary systems rather than the metric system, so the relationship is fixed and tidy: there are exactly 12 inches in one foot. Unlike metric conversions that hinge on the meter, this is a base-12 (duodecimal-style) split that the foot was historically divided into — which is why 12 shows up here instead of a power of ten.
The rule of thumb is simply "multiply by 12," and a quick mental shortcut is to multiply by 10 and add two more groups: for 7 ft, take 70 and add 14 to get 84 inches. Handy anchors worth memorizing are 1 ft = 12 in, 3 ft (a yard) = 36 in, and 6 ft = 72 in.
The most common mistake happens with mixed measurements like 5 ft 8 in. People sometimes multiply 5.8 by 12, but the "8" is already inches, not eight-tenths of a foot — you must convert only the 5 feet (60 in) and then add the 8 to get 68 inches. Watch the same trap with feet-and-inches written as 5'8".
