Example
A height of 170 cm converts to 5' 6.9" (about 66.9 total inches, or 1.70 m). Going the other way, 5 ft 7 in equals 170.2 cm.
How it works
1 inch = 2.54 cm, so cm = (feet x 12 + inches) x 2.54, and to go the other way total inches = cm / 2.54, with feet = floor(inches / 12) and remaining inches = inches mod 12.
Good to know
The Height Converter turns a height written in centimeters into feet and inches, or the reverse, the moment you type. It's the everyday tool for anyone caught between metric and imperial systems: filling out a US visa or job application that wants feet/inches, reading a European passport or medical chart in centimeters, comparing your own height against an athlete's stats, or quoting a doorway, mirror, or growth-chart measurement to someone in another country.
Pick a direction with the toggle at the top, then type into the field. The big number is your converted height, and the four stat tiles break the same value into centimeters, feet and inches, total inches, and meters so you can copy whichever format the form in front of you is asking for. Total inches is handy for spreadsheets and BMI formulas; meters is the one to grab for height-squared health calculations.
One thing worth knowing: the inches reading carries a decimal (for example 5' 6.9") because most centimeter heights don't fall exactly on a whole inch. That decimal is the accurate answer, not an error. If a form only accepts whole inches, round it yourself, but be aware that rounding 6.9" up to 7" nudges your stated height by roughly a centimeter.
- cm to ft/in: enter a single centimeter value, ideal for converting a clinic or tape-measure reading.
- ft/in to cm: enter feet and inches separately, ideal for converting a height you already know in imperial.
Frequently asked questions
How many centimeters are in a foot?
There are 30.48 cm in one foot, since a foot is 12 inches and each inch is exactly 2.54 cm (12 x 2.54 = 30.48).
Why does the inches value have a decimal?
Centimeters rarely land on a whole inch, so the converter shows the leftover as a decimal (e.g. 5' 6.9") for accuracy. You can round to the nearest inch if you only need an approximate height.

People also ask
How tall is 170 cm in feet and inches?
170 cm is about 5 feet 6.9 inches, which is roughly 5 feet 7 inches when rounded. That equals about 66.9 total inches or 1.70 meters.
What is 6 feet in centimeters?
6 feet equals 182.88 cm, because each foot is exactly 30.48 cm (6 x 30.48). It rounds to about 183 cm.
How do I convert cm to feet and inches manually?
Divide the centimeters by 2.54 to get total inches, then divide that by 12. The whole number is your feet and the remainder is your leftover inches.
What is the average human height in cm and feet?
Globally the average adult man is around 171 cm (about 5'7") and the average adult woman around 159 cm (about 5'2.6"), though this varies widely by country. Use the converter to translate any local average into the units you prefer.
Should I round my height up or down on a form?
Round to the nearest whole inch rather than always up or down, so the stated height stays closest to your real measurement. For official documents, follow whatever rounding rule the form specifies, or enter the decimal if it allows one.
How many inches is 5 feet 9 inches in total?
5 feet 9 inches is 69 total inches, since 5 feet is 60 inches plus the extra 9. In centimeters that is about 175.3 cm.
Is a foot exactly 30 cm?
No, a foot is 30.48 cm exactly, not a round 30. The 0.48 cm difference adds up over taller heights, so use the precise value for anything that matters.
Does this height converter work without internet?
Yes, once the page has loaded it runs entirely in your browser and keeps converting offline. Nothing you type is sent to a server.
How tall will I be if my mom is 5'3" and my dad is 5'10"?
Using the common mid-parental height estimate, a son would be about 5 ft 9 in and a daughter about 5 ft 4 in. The method adds both parents' heights in inches, adds 5 inches for a boy or subtracts 5 for a girl, then halves the result: (63 + 70 + 5) / 2 = 69 in for a boy and (63 + 70 - 5) / 2 = 64 in for a girl, with a range of roughly plus or minus 4 inches. In centimeters that is 175.3 cm and 162.6 cm respectively. This is a rough estimate, not a medical prediction; nutrition, health and genetics from further back in the family all matter.
How tall will I be if I'm 5'3" at 13?
There is no exact answer from height alone, because it depends on your sex and how far along puberty is. Five feet three inches is 63 in x 2.54 = 160 cm; many girls at 13 are close to their adult height, while boys of 13 often still have several inches of growth ahead. A doctor estimates adult height by plotting your measurements on a growth chart over time and, if needed, checking bone age with an X-ray. This is general information, not medical advice.
How tall will my son be if he is 5'4" at 12?
A 12-year-old boy who is 5 ft 4 in (64 in, or 162.6 cm) is taller than most boys his age and usually still has his main growth spurt ahead, which typically comes between about 12 and 15. A rough adult estimate comes from the mid-parental method: add both parents' heights in inches plus 5, then halve. For a more reliable projection, a pediatrician tracks his height percentile on a growth chart over several visits. This is general information, not medical advice.
How tall will my son be if he is 5'8" at 14?
At 14, a boy who is 5 ft 8 in (68 in, or 172.7 cm) is already above the average adult male height in many countries, and boys commonly keep growing until about 16 to 18. How much more depends on where he is in puberty; if his growth spurt has already peaked, a further 1 to 3 inches is typical, and if it has not, more is possible. A pediatrician can estimate this from his growth-chart percentile and, if needed, a bone-age X-ray. This is general information, not medical advice.
Is being 6 ft at 14 rare?
Yes, 6 ft (72 in, or 182.9 cm) at 14 is uncommon; it is well above the typical height for that age and taller than the average adult man in most countries. It usually reflects an early or strong growth spurt, and such teens often end up tall adults, though growth slows once puberty finishes. It is not by itself a sign of a problem, but if growth seems unusually fast a pediatrician can check; this is general information, not medical advice.
Can I grow from 5'7" to 6'0"?
Growing from 5 ft 7 in to 6 ft means gaining 5 inches, or 12.7 cm (67 in versus 72 in, each x 2.54). That is realistic only if you are still growing, which for most people means before the growth plates in the long bones close, typically in the mid-to-late teens for girls and late teens for boys. Adults do not gain height, though good posture can make you measure slightly taller. This is general information, not medical advice.
