Twelve inches to the foot
This is about as clean as unit conversion gets. A foot is exactly 12 inches. Always has been, no decimals lurking, no historical fudge factor. Multiply your feet by 12 and you’ve got inches. That’s the whole rule.
Type a value and the answer shows up as you type. Everything runs in your browser, so your numbers stay on your machine and there’s no server doing the arithmetic.
Why people reach for this
Height is the obvious one. Americans say “five eight” or “six foot two,” but a lot of charts, growth records, and clothing size guides want the figure in plain inches. Five foot eight is 68 inches. Six foot two is 74 inches. Add the leftover inches to twelve times the feet and you’re done.
Lumber and building materials are where this really earns its keep. Hit a hardware store and dimensions blur between the two units constantly. An 8-foot 2x4 is 96 inches long. A sheet of plywood listed as 4 feet by 8 feet measures 48 by 96 inches, which matters when you’re laying out cuts and the saw fence is marked in inches.
Furniture shopping runs into it too. A sofa described as “7 feet wide” is 84 inches across. Before you order, check that against the 84-inch (or whatever) gap on your wall. Couches that look fine in a showroom have a habit of not clearing doorways once you do the inch math.
Some figures to anchor on
- 1 ft = 12 in
- 2 ft = 24 in
- 5 ft = 60 in
- 6 ft = 72 in
- 10 ft = 120 in
Notice the pattern: every foot adds exactly 12 inches, so you can scale any whole number in your head. Half a foot is 6 inches. A foot and a half, 18.
How the tool works
Punch feet into the input field. Inches appear live, no button to press. The dropdown lets you reverse direction or jump to centimeters and meters, so you’re not stuck on one conversion. Below the field sits a reference table for the values people check most, which is often faster than typing.
For mixed measurements like 5 feet 9 inches, convert the feet portion (5 × 12 = 60) and add the loose inches (9) to get 69 inches total. The display rounds sensibly, though with feet-to-inches there’s rarely a rounding question since it’s all whole multiples of 12.
Common questions
How many inches are in a foot?
Exactly 12. No rounding, no approximation. It’s a defined relationship that’s been fixed for centuries.
What is 6 feet in inches?
72 inches. Six times twelve. A common doorway is around 80 inches tall, so a 6-foot person clears it with room to spare.
How do I convert feet and inches to total inches?
Multiply the feet by 12, then add the inches. So 5’10” is (5 × 12) + 10 = 70 inches. Handy when a size chart only accepts a single inch value.
Why would I convert feet to inches at all?
Mostly precision and tooling. Tape measures, sewing patterns, and cut lists work in inches, so breaking feet down lets you mark and measure without converting on the fly.
Does this send my measurements anywhere?
Nope. The calculation is browser-side JavaScript. Load the page and you can disconnect from the internet; it’ll keep converting fine.
