Enter a value in feet and read the result in inches straight away. Feet turn into inches most often for height, equipment sizes and screen diagonals. Watch the height notation, though: 5 feet 7 inches is not the same as 5.7 feet. A separate table lower down shows how many inches a height in feet and inches comes to.
Feet and inches sit side by side in everyday measuring, so you convert whenever a value in feet has to read in the finer unit: a height you want stated in inches, a size you need to compare with a screen diagonal, or a dimension given in feet where you want the exact inch figure.
The relationship is simple and exact: one foot is 12 inches. To turn feet into inches, you multiply the number of feet by 12. The converter does that for you the moment you type a value.
There is a catch in the height notation, though. "5 feet 7 inches" is not the same as "5.7 feet". The converter takes a single number, so if you type 5.7 it works out 5.7 × 12 = 68.4 inches. But 5 feet 7 inches is 67 inches. So convert a height in feet and inches with the table below, not by typing it with a decimal point.
Converting feet to inches rests on one fixed relationship: one foot is exactly 12 inches. To turn feet into inches, you multiply the number of feet by 12.
Full formula: inches = feet × 12. The other way round: feet = inches ÷ 12.
Example: you want to know how many inches 6 feet is. You substitute: 6 × 12 = 72 inches. It is the most frequently converted value, because "six feet" is a common height in English-speaking countries.
Mind the height notation. If you have 5 feet 7 inches, do not type 5.7, because the converter would work out 68.4 inches. You get the inches of a height like this: multiply the feet by 12 and add the inches. For 5 feet 7 inches that is 5 × 12 + 7 = 67 inches. Ready values are in the height table below.

Feet turn into inches in a handful of everyday situations.
6 feet is 72 inches. The calculation: 6 × 12 = 72 inches. It is the most frequently converted value, because "six feet" is a common height in English-speaking countries.
5 feet is 60 inches. The calculation: 5 × 12 = 60 inches. That is also the height 5 foot 0.
5 feet 7 inches is 67 inches. The calculation: 5 × 12 + 7 = 67 inches. Do not confuse it with 5.7 feet, which gives 68.4 inches — that is a completely different notation.
No. 5.7 feet is a decimal figure and gives 5.7 × 12 = 68.4 inches. A height of 5 feet 7 inches is 67 inches. The gap comes from the fact that 0.7 of a foot is 8.4 inches, not 7 inches. Always write height as separate feet and inches.
5 feet 10 inches is 70 inches. The calculation: 5 × 12 + 10 = 70 inches.
3 feet is 36 inches, and 4 feet is 48 inches. You get both by multiplying the number of feet by 12.
12 feet is 144 inches. The calculation: 12 × 12 = 144 inches. The same number, 144, is also the number of square inches in a square foot, but that is a different quantity.
67 feet is 804 inches. The calculation: 67 × 12 = 804 inches. If you were after the height 5 feet 7 inches, that is 67 inches, not 67 feet.
Multiply the feet by 12 and add the inches. Example: 6 feet 2 inches is 6 × 12 + 2 = 74 inches. Ready values for the most common heights are in the table above.
The formula is: inches = feet × 12. For example, 7 × 12 = 84 inches. The other way round: feet = inches ÷ 12.
No. This tool converts length, and a square foot is a unit of area. The factor is different: 1 square foot is 144 square inches, so you multiply an area in square feet by 144.
No. Pound-feet and pound-inches are units of torque, not length, so this converter does not handle them. The factor is the same (1 pound-foot is 12 pound-inches), but it is a different physical quantity.
