- Is 5.74 feet the same as 5 feet 7.4 inches?
- No, and this is the most common mistake with decimal feet. The part after the point is a fraction of a foot, not inches. 0.74 ft × 12 = 8.9 in, so 5.74 ft is 5 ft 8.9 in. Reading it as 5 ft 7.4 in makes someone 1.5 inches shorter than they are. That's why the main answer here is already split into feet and inches.
- How do I convert cm to feet and inches by hand?
- Divide the centimeters by 2.54 to get inches. Divide the inches by 12: the whole number is feet, and the remainder is inches. 175 cm ÷ 2.54 = 68.9 in. 68.9 ÷ 12 = 5 with 8.9 left over, so 175 cm is 5 ft 8.9 in. Going straight to feet (175 ÷ 30.48 = 5.74 ft) is one step shorter but leaves you with the decimal-feet trap above.
- Is there a quick mental shortcut?
- Multiply centimeters by 0.4 to get rough inches, then split into feet. 175 × 0.4 = 70 in, or 5 ft 10 in. The exact answer is 5 ft 8.9 in, so the shortcut runs about 1.6% high — around an inch on an adult height. Fine for a ballpark. Not fine for a passport form, a medical chart, or a doorway you're hoping a wardrobe fits through.
- Why is a foot exactly 30.48 cm?
- Because the inch is defined as exactly 2.54 cm. The US, UK, Canada, Australia, New Zealand, and South Africa agreed on that in 1959, and a foot is 12 inches, so a foot is 30.48 cm with nothing after it. Converting feet to centimeters is an exact multiply. Converting centimeters to feet gives a decimal that often goes on forever, which is why the answer here is rounded for display and the copyable formula shows the steps.
- Is 183 cm six feet?
- Six feet is 182.88 cm, so 183 cm is a hair over — 6 ft 0.05 in — and rounds to 6 ft 0 in. 180 cm, which people often round to six feet, is actually 5 ft 10.9 in. If you're listing a height in feet, round the inches to the nearest whole number: 5 ft 10.9 in becomes 5'11".
- What's the tape-measure reading for?
- US tape measures are marked in fractions of an inch, not tenths. If you're cutting a shelf, hanging a picture, or checking whether a 60 cm dishwasher fits a gap, a reading like 1 ft 11 5/8 in is what you'll actually find on the tape. This tool rounds to the nearest 1/8 inch, which is about 3 mm — closer than most people can mark a pencil line.
- Does a 200 cm door fit a standard US door frame?
- Probably not as a swap. 200 cm is 6 ft 6.7 in. A standard US interior door is 80 inches tall (6 ft 8 in, or 203.2 cm), so a 200 cm European door is about 1.3 inches short of the usual US opening. Measure the actual frame before you buy.
- What about the US survey foot?
- The US survey foot was slightly longer than the regular foot — about 30.48006 cm, a difference of 2 parts per million. It only ever mattered for land surveys over long distances, and the US officially retired it at the end of 2022. For heights, rooms, furniture, and anything else, the 30.48 cm foot used here is the right one.
- Is what I type saved or sent anywhere?
- No. The conversion runs in your browser. Nothing is sent to a server or stored, and closing the tab clears it.
