How to Use This Height Converter
The US measures people in feet and inches while most of the world uses centimeters, which makes medical forms, sports stats, and online shopping confusing. Tell the tool which unit you know, enter the numbers, and get the exact equivalent both ways.
Choose whether you know your height in feet/inches or centimeters.
Enter the values. Inches accept decimals, so 5 ft 9.5 in works fine.
Read the converted height plus meters and total inches for reference.
The Conversion
The inch is defined as exactly 2.54 centimeters, so these conversions are exact, not approximate. Five feet nine inches is (5 Γ 12 + 9) = 69 inches Γ 2.54 = 175.26 cm. Going back, 175 cm Γ· 2.54 = 68.9 inches = 5 feet with 8.9 inches left over.
Why Height Units Differ
The US customary system stuck with feet and inches for body measurement out of tradition, while the metric world standardized on centimeters for precision. Medicine straddles both: US charts record 5β²9β³, but BMI formulas need meters, and international records use centimeters. Airlines, clothing brands, and sports leagues each pick the unit their audience expects, so conversion is a daily need.
Worked Example
A basketball roster lists a player at 6β²7β³. Total inches = 6 Γ 12 + 7 = 79. Centimeters = 79 Γ 2.54 = 200.66 cm, usually rounded to 201 cm. Reverse: a European ID says 183 cm. Inches = 183 Γ· 2.54 = 72.05, which is 6 feet and 0.05 inches, so 6β²0β³.
Measuring Tips
Stand barefoot against a wall, mark the top of your head with a book held level, and measure to the floor. Morning height runs about 1 to 2 cm taller than evening because spinal discs compress during the day. Round to the nearest half inch or centimeter for everyday use; medical dosing should use a proper stadiometer measurement.
Average Heights Around the World
Average adult height varies dramatically by country. Dutch men average about 183 cm (6β²0β³) and Dutch women about 170 cm (5β²7β³), the tallest national averages in the world. In the United States, men average roughly 175 cm (5β²9β³) and women 162 cm (5β²4β³). Globally, the average adult man is about 171 cm and the average woman about 159 cm. These differences come from genetics, nutrition, and healthcare, and they shift measurably within a single generation when childhood nutrition improves.
Sports make height conversion a daily task: the NBA lists players in feet and inches for US fans but centimeters for international broadcasts, and Olympic records are always metric. Clothing is another hotspot: European size charts assume centimeters, so knowing that a 32-inch inseam equals 81 cm saves a return. Use this converter whenever a form, chart, or broadcast speaks the other system.
Frequently Asked Questions
How tall is 5 ft 9 in in cm?
175.26 cm, usually rounded to 175 cm. Calculate: (5 Γ 12 + 9) = 69 inches Γ 2.54 = 175.26 cm.
How do I convert cm to feet and inches?
Divide cm by 2.54 to get total inches, then divide by 12 for feet. For 180 cm: 180 Γ· 2.54 = 70.87 inches = 5 feet 10.87 inches, or 5β²10.9β³.
What is 6 feet in cm?
182.88 cm, rounded to 183 cm. Six feet equals 72 inches Γ 2.54.
Why does the US use feet and inches for height?
Tradition. The US never completed metrication, so customary units persist for body measurements, while science, medicine calculations, and most of the world use metric.
How accurate should my height conversion be?
To the nearest centimeter or half inch for everyday use. Your height varies 1 to 2 cm through the day, so extreme precision is meaningless outside clinical settings.
