About Foot to Inch Converter
Converting feet to inches is one of the simplest unit conversions in the imperial system — by definition, one foot equals exactly twelve inches. The relationship has been fixed since the international yard and pound agreement of 1959, and it underpins virtually every imperial-system measurement task: heights, ceiling clearances, lumber dimensions, screen sizes, and shipping dimensions. Despite the simplicity of the formula, doing the multiplication mentally for non-whole numbers (like 5.75 ft or 11 ft 3 in) gets tedious, which is where a calculator helps.
The conversion formula is direct: inches = feet × 12. A six-foot board is 72 inches. A ten-foot ceiling is 120 inches. A standard 8-foot sheet of plywood is 96 inches long. For decimal feet — common in CAD output or surveying — the math is the same: 5.25 ft = 63 in, 12.5 ft = 150 in. Going the other way, divide by 12: 144 in = 12 ft, 100 in = 8.33 ft (or 8 ft 4 in).
The most common everyday use is converting personal height. American medical records, fitness trackers, and dating profiles often quote height in pure inches — “she’s 68 inches tall” — when the same person would say “five foot eight” in conversation. Converting between the two is a quick × 12 (for the feet portion) followed by adding the leftover inches. The same applies to children’s growth charts, sports scouting reports (where wingspan is sometimes quoted in inches), and uniform sizing.
In trades and DIY, the conversion happens whenever you need to add or subtract a small measurement from a larger one. A 6-foot beam needs a 4-inch notch — easier to work with as 72 inches and subtract 4 than to fiddle with feet-and-inches arithmetic. Cabinet makers, carpenters, and tilers regularly convert finished plans from feet to inches when laying out materials.
This converter shows the inches result as the primary output, alongside centimetres (multiplying feet by 30.48), millimetres, and metres. Results update live as you type. The copy button grabs the inches value, and the clear button resets the input.

Frequently asked questions
One foot equals exactly 12 inches. This is a fixed, defined relationship in the imperial system — there is no rounding involved. To convert any feet value to inches, multiply by 12.
Multiply the number of feet by 12. For example, 5 ft × 12 = 60 in. To convert inches back to feet, divide by 12: 84 in ÷ 12 = 7 ft.
Multiply by 12 directly — 5.5 × 12 = 66 inches. Or convert the fractional part separately: 0.5 ft = 6 in, so 5.5 ft = 5 ft 6 in. The tool shows the total inches; you can split into feet-and-inches mentally by dividing by 12 (whole part = feet, remainder = inches).
Personal height (a 5 ft 8 in person is 68 inches tall — common in medical records), screen and TV dimensions in inches, carpentry and DIY plans (a 6-foot board is 72 inches), and any application where you need to add or subtract small lengths within a larger overall measurement.
