The Height ft to cm Calculator converts a height given in feet and inches into centimeters, the format used almost everywhere outside the United States. Enter feet and inches, and the tool combines them into total inches, then multiplies by 2.54 to return the centimeter figure.
Feet-and-inches height is written as a mixed unit, a whole number of feet plus a remainder in inches, which makes it awkward to compare directly with a single metric figure. This page starts from that everyday format and walks through feet to cm and height to cm conversions without changing the numbers.
Convert feet and inches to cm
To convert feet and inches to cm, multiply the feet by 12 to get inches, add the remaining inches, then multiply the total by 2.54. The same steps cover ft and inches to cm when the input uses the short labels.
cm = ((feet × 12) + inches) × 2.54Convert ft and inches to cm with a worked example
Worked example: convert 5 feet 10 inches to centimeters.
1. Convert feet to inches. 5 × 12 = 60 inches.
2. Add the remaining inches. 60 + 10 = 70 total inches.
3. Multiply by 2.54. 70 × 2.54 = 177.8 cm.
So a height of 5'10" equals 177.8 cm exactly, since both input numbers were whole values and 2.54 is an exact conversion factor.
Convert height feet to cm using total inches
Height feet to cm works like a mixed number: the feet portion counts whole 12-inch blocks, and the inches portion is always less than 12, since 12 inches would simply become one more foot. Converting to a single centimeter figure removes that two-part structure, which is one reason metric height figures are easier to compare or average.
The 2.54 factor at the end is exact by international definition, so you do not lose precision when the input is a whole number of feet and inches. Any rounding in the final centimeter figure only comes from choosing how many decimal places to display.
Convert feet to cm for common heights
| Feet and inches | Centimeters |
|---|---|
| 5'0" | 152.4 cm |
| 5'4" | 162.56 cm |
| 5'8" | 172.72 cm |
| 5'10" | 177.8 cm |
| 6'0" | 182.88 cm |
| 6'4" | 193.04 cm |
Each row follows the same two-stage rule: total inches times 2.54. Six feet, a commonly referenced height benchmark, converts to 182.88 cm exactly. That is the plain feet to cm result when inches are zero.
Convert ft to cm from whole feet only
When inches are zero, ft to cm is just feet × 12 × 2.54. So 6 ft equals 72 × 2.54 = 182.88 cm, matching the table row above.
Convert foot to cm for one foot
One foot is exactly 12 inches, so foot to cm is 12 × 2.54 = 30.48 cm. Every taller figure on this page is built by stacking that block and then adding leftover inches.
Convert height to cm back into feet and inches
The Height ft to cm Calculator also runs the reverse direction. To turn height to cm readings back into feet and inches, divide by 2.54 to get total inches, then split that into whole feet and a remaining inch count.
total inches = cm ÷ 2.54
feet = floor(total inches ÷ 12)
inches = total inches − (feet × 12)Worked example: convert 180 cm to feet and inches.
1. Divide by 2.54. 180 ÷ 2.54 ≈ 70.87 inches.
2. Find whole feet. 70.87 ÷ 12 ≈ 5.91, so 5 whole feet.
3. Find remaining inches. 70.87 − 60 = 10.87 inches.
So 180 cm is approximately 5 feet 10.9 inches, often rounded to 5'11" in casual conversation.
Match feet in cm when you compare records
When two heights are recorded in different formats, converting both to the same unit before comparing avoids small rounding mismatches. Forms that ask for feet in cm usually want that single metric number, not a mixed feet-and-inches string.
A height listed as "5'10"" already carries some rounding, since real height is a continuous measurement. Converting it to 177.8 cm and comparing against a metric measurement recorded to the nearest millimeter can introduce an apparent difference that is really just measurement precision, not an actual height gap.
Check feet to cm height at short and tall ends
Checking the formula outside the 5-to-6.5-foot table above confirms it holds at both ends of the height range. Worked example: convert 4 feet 9 inches to centimeters.
1. Convert feet to inches. 4 × 12 = 48 inches.
2. Add the remaining inches. 48 + 9 = 57 total inches.
3. Multiply by 2.54. 57 × 2.54 = 144.78 cm.
Worked example: convert 6 feet 6 inches to centimeters.
1. Convert feet to inches. 6 × 12 = 72 inches.
2. Add the remaining inches. 72 + 6 = 78 total inches.
3. Multiply by 2.54. 78 × 2.54 = 198.12 cm.
Both examples use the same multiply-and-add process shown earlier on this page, so 4'9" becomes 144.78 cm and 6'6" becomes 198.12 cm. A child's height or an unusually tall adult converts through the same three-step sequence used for the 5'10" example above.
Why height ft to cm still needs both systems
Feet and inches remain the everyday standard for describing adult height in the United States, the United Kingdom and a handful of other countries, even though centimeters are used almost everywhere else and in most medical and scientific records.
That is why height ft to cm tools get used so often. A form, a passport, or a doctor's chart may require centimeters even when someone thinks of their height in feet and inches, and converting by hand invites the rounding slips covered above.
Frequently asked questions
How do you convert feet and inches to cm?
Multiply the feet by 12 to get inches, add the remaining inches, then multiply the total by 2.54. For 5'10", that gives (60 + 10) × 2.54 = 177.8 cm.
What is height feet to cm for 5'10"?
5 feet 10 inches equals 177.8 cm exactly.
What is 6 feet in centimeters?
6 feet equals 72 inches, and 72 × 2.54 = 182.88 cm. That is the same feet to cm path with zero leftover inches.
How do you convert cm back to feet and inches?
Divide the centimeter value by 2.54 to get total inches, then divide by 12 to find whole feet, keeping the remainder as inches.
How many inches are in one foot?
Exactly 12 inches make one foot, a fixed relationship used in every feet-and-inches height figure. That is why foot to cm is always 30.48 cm.
Is the 2.54 cm-per-inch conversion exact?
Yes. One inch is defined as exactly 2.54 centimeters, so no rounding error comes from that step alone.
Why do height figures sometimes differ by a fraction of a centimeter between sources?
Differences usually come from rounding a feet-and-inches figure to the nearest whole inch before converting, or displaying only whole centimeters instead of one decimal place.
Summary
Converting feet and inches to cm means turning the feet into inches, adding the remainder, and multiplying by exactly 2.54, so 5'10" becomes 177.8 cm and 6'0" becomes 182.88 cm. The reverse height to cm path divides by 2.54 and splits the result into whole feet plus leftover inches.
Because 2.54 is an exact factor, all rounding in either direction comes from how the height was originally recorded or displayed. Use the Height ft to cm Calculator above when you need feet to cm height figures without doing the arithmetic by hand.
