180cm converts to 5’11” in everyday feet/inches display (more precisely, about 5’10.9”). It’s also a moderately tall height for a man: against the CDC/NHANES US reference, 180cm sits at roughly the 75th percentile, above both the US and UK average male height.

| Feet and inches (rounded) | 5’11” |

180cm rounds to 5’11” because feet/inches display on this site rounds to the nearest half inch, and 70.87in rounds to 71.0in, which is exactly 5’11”. The precise figure, 5’10.9”, is about 0.13in short of a true 5’11” (180.34cm) — a gap smaller than a fingernail’s width, but worth knowing if you need an exact match.

Why 180cm and 5’11” aren’t an exact match
Centimetres and feet/inches are both continuous scales, but 180cm doesn’t land on a round feet/inches number. One foot is 30.48cm and one inch is exactly 2.54cm, so converting 180cm gives 70.8661 inches — a figure with a long decimal tail, not a clean 71.0.
This site’s converter rounds feet/inches display to the nearest half inch for readability, which is why 180cm shows as 5’11” rather than 5’10.9” or 5’10.87”. For most everyday purposes — clothing sizes, describing your own height, casual comparisons — the rounded figure is close enough. For anything that needs precision, such as matching a specific listed height exactly, use the unrounded 70.87in or 180.0cm figure instead.
Is 180cm actually tall?
Yes, by a meaningful margin. 180cm is about 3.1cm above the US average adult male height (176.9cm) and about 1.8cm above the UK average (178.21cm). Against the CDC/NHANES US adult male reference, it works out at roughly the 75th percentile — taller than about three-quarters of adult men.
That’s a bigger gap than “slightly above average.” A 75th-percentile height puts someone clearly in the taller half of the distribution, though still well short of the tall tail — heights like 6’0” (182.9cm, 86th percentile) or 6’2” (188cm, roughly 96th percentile) sit further out.
Why cm and feet/inches coexist
Most of the world uses metric units for height, including centimetres in medical and everyday contexts. The US, and to a lesser extent the UK, still commonly uses feet and inches in casual conversation, even where official records use centimetres or metres.
That split is why a conversion tool matters: a height quoted in one system needs translating before it means much to someone used to the other. This site detects a likely default from your browser’s language settings, then lets you switch units freely, since neither system is more “correct” than the other — they’re just different scales for the same underlying measurement.
Measuring your height accurately
If you’re checking your own height against these figures, small measurement errors can shift the result more than you’d expect at this level of precision. Stand fully upright without shoes, heels and shoulder blades against a flat wall, and use a rigid flat object, not a tape measure alone, to mark the top of your head against a wall-mounted ruler.
Height also varies slightly across the day, typically reading a touch taller in the morning than in the evening, because the spine compresses gradually while standing or sitting. Given that 180cm and 5’11” already differ by a fraction of a centimetre before any measurement error, it’s worth measuring at a consistent time of day if you need a precise figure rather than a rounded one.
180cm is not the same as 6 feet
A common assumption is that 180cm and 6 feet are roughly interchangeable, but they’re not quite the same height. Six feet is 182.88cm — about 2.9cm taller than 180cm, or a little over an inch.
That gap is enough to matter for anything precise, such as a listed height on an official document or a sizing chart. 180cm is closer to 5’11” than to 6’0”, even though both get rounded casually to “just under six foot” in everyday conversation.
Check the percentile for yourself
The same LMS method used throughout this site converts 180cm into an age- and sex-specific percentile. Try it below, pre-filled to 180cm against the CDC adult reference — switch the reference to WHO, or change the age, to see how the answer shifts.
This reference covers ages 2-20; using the nearest available data point for age 30.

At 180 cm and age 30, you are taller than approximately 75% of the CDC reference population for your sex.

Nearby centimetre values, converted
The same rounding rule that turns 180cm into 5’11” applies to any nearby value. Here’s how the closest round centimetre figures convert, all derived using the exact 2.54cm-per-inch definition and rounded to the nearest half inch:
| Centimetres | Feet and inches |
|---|---|
| 175cm | 5’9” |
| 178cm | 5’10” |
| 180cm | 5’11” |
| 183cm | 6’0” |
Notice that 178cm and 183cm land on clean feet/inches values, while 180cm and 175cm don’t quite. That’s simply a property of where 30.48cm (one foot) and 2.54cm (one inch) fall relative to the metric scale — there’s no pattern that makes “nicer” centimetre numbers convert more cleanly than others in general.
Common mix-ups when converting cm to feet
A frequent source of confusion is rounding to the nearest whole inch instead of the nearest half inch, which can shift a borderline value like 180cm to 5’11” either way depending on the calculator used. Always check which rounding convention a given tool uses before relying on it for something that needs precision, such as matching an official record.
Another common mix-up is confusing total inches with feet-and-inches format — 180cm is 70.87 total inches, not 70 feet 87 inches, a distinction that matters when reading raw conversion output from a calculator that doesn’t format it for you.
How this figure was calculated
The conversion uses the exact international definition of an inch (1in = 2.54cm exactly): 180cm ÷ 2.54 = 70.8661in, which rounds to 70.9in (5’10.9”) when kept to one decimal, or to the nearest half inch (5’11”) for the site’s standard feet/inches display.
The percentile was calculated using the LMS method against the CDC/NHANES adult (20+) reference point for men: M (median) = 175.1cm, S (coefficient of variation) = 0.041064, L = 1. The z-score works out to z ≈ 0.681, which converts to the 75.2nd percentile via the standard normal distribution.
Country averages (US and UK) come from this site’s country dataset, itself compiled from NCD-RisC’s 2019 cohort figures (age 19). The CDC/NHANES adult figure is a single aggregate for everyone aged 20 and over, not broken out by decade — see the percentile tool’s own “Method and sources” section for the full data-provenance notes.
The unit conversion itself carries no uncertainty — it follows directly from the exact 2.54cm-per-inch definition. The percentile figure, by contrast, is a close approximation, since the CDC/NHANES adult S value is estimated from published percentile columns rather than an official LMS fit. Treat 75th percentile as indicative rather than exact to the decimal place.
