How to Convert Feet to cm
1 foot = 30.48 cm. This means 6 feet equals 182.88 cm, a handy reference since that is roughly average male height in many countries.
Feet are the standard length unit in the United States and are still used informally in the UK and Canada. If you are working with metric measurements, you will need to convert feet to centimeters for anything from height calculations to furniture dimensions.
- Enter your value in feet in the calculator above.
- The calculator multiplies your value by 30.48 to give the result in centimeters. To do this manually, take the number of feet and multiply by 30.48.
- For example, 5 feet: 5 x 30.48 = 152.4 cm.
Formula
cm = feet x 30.48
The factor 30.48 comes from the international yard and pound agreement (1959), which defined one foot as exactly 0.3048 meters, or 30.48 centimeters. Multiply the number of feet by 30.48 and you get the equivalent length in centimeters.
Worked example: 3 feet x 30.48 = 91.44 cm.

Real-World Examples
A standard interior door in the US is 6.67 feet tall (6 feet 8 inches). That works out to 6.67 x 30.48 = 203.3 cm, which is why metric door frames are typically labeled 203 cm.
Ceiling height in most American homes is 8 feet, or 243.84 cm. In metric countries this is rounded to 240 or 250 cm.
A regulation basketball hoop stands 10 feet above the floor. That equals 304.8 cm, the same worldwide regardless of measurement system.
Airline carry-on luggage limits often reference 1.5 feet (45.72 cm) for the longest side. Knowing both units helps when shopping for bags labeled in metric sizes.
For Students
Feet-to-centimeters conversion shows up in standardized tests like the SAT and ACT, especially in word problems involving measurement. The most common mistake is confusing feet with inches. Remember: 1 foot = 12 inches, and 1 foot = 30.48 cm. A quick memory trick: 30 cm is roughly one foot, so a 6-foot person is close to 180 cm. Try converting your own height and a friend’s height to practice. Use the calculator above to check your work.
Frequently Asked Questions
How many cm are in one foot?
One foot equals exactly 30.48 centimeters. This is an exact value defined by international agreement since 1959, not an approximation.
Is a foot bigger than a centimeter?
Yes. One foot is about 30 times longer than one centimeter. A centimeter is roughly the width of a pencil, while a foot is the length of a standard ruler.
How do I convert feet to cm without a calculator?
Multiply the number of feet by 30.48. For a quick estimate, multiply by 30 and add roughly half a centimeter per foot. For example, 4 feet is about 4 x 30 = 120 cm, plus 4 x 0.48 = 1.92, giving 121.92 cm.
Why does the US still use feet instead of centimeters?
The US customary system evolved from British imperial units and was never officially replaced. While science and medicine in the US use metric, everyday measurements like height and room dimensions still use feet and inches by convention.
How tall is 5 feet 10 inches in cm?
5 feet 10 inches is 5.833 feet, which equals 177.8 cm. You can convert feet and inches separately: 5 x 30.48 = 152.4 cm, plus 10 x 2.54 = 25.4 cm, totaling 177.8 cm.
