Feet to inches: the simplest imperial conversion
One foot is exactly 12 inches, so converting feet to inches is nothing more than multiplying by 12. There are no awkward decimals and no rounding — the relationship was fixed by definition centuries ago and has never changed. Since 1959 both units have also been tied to the metric system: one inch is exactly 25.4 millimeters, which makes one foot exactly 304.8 millimeters.
How to do it by hand
Multiply the number of feet by 12. If the measurement is given as feet and inches, multiply only the feet part and then add the inches: 6 ft 3 in = 6 × 12 + 3 = 75 inches.
For decimal feet the same rule applies: 2.5 feet = 2.5 × 12 = 30 inches. A handy mental shortcut is to multiply by 10 and then add double the original number: 7 feet → 70 + 14 = 84 inches.
Typical values
- 1 foot = 12 inches
- 3 feet = 36 inches (one yard)
- 5 feet = 60 inches
- 6 feet = 72 inches
- 8 feet = 96 inches (a standard ceiling height)
- 10 feet = 120 inches
Where you will need it
Builders and DIY enthusiasts convert feet to inches constantly, because plans are drawn in feet while cuts are marked in inches. Photographers and print shops do the same with poster and banner sizes. Online shopping for curtains, blinds, rugs or garden hoses often lists the length in feet, while the space you measured at home is in inches.
A note on fractions
Tape measures in the United States show inches divided into halves, quarters, eighths and sixteenths, not tenths. When a conversion gives you 0.25 inch, that is a quarter; 0.125 is an eighth; 0.0625 is a sixteenth. Round to the nearest sixteenth if you are transferring a number onto a tape measure.
