How to Convert Feet to Centimeters (Exact Formula & Height Math)
Converting feet to centimeters is a cornerstone calculation across human stature measurement, architectural drafting, aviation ceiling charts, and international shipping. Under the 1959 International Yard and Pound Agreement, the imperial foot is defined in terms of metric units: exactly 1 foot equals 0.3048 meters, which is 30.48 centimeters.
Multiply the decimal feet value directly by 30.48. For instance, 6 ft × 30.48 = 182.88 cm.
Convert feet to centimeters, inches to centimeters (at 2.54 cm/in), then sum both products.
For inverse conversions, divide centimeters by 30.48 or use our sister tool, the Centimeters to Feet Converter (cm to ft). If your project requires metric base units, explore our Feet to Meters Converter and Inches to Centimeters Converter.

Human Height Conversion Guide: Imperial (ft/in) to Metric (cm)
One of the most frequent uses of feet-to-centimeters conversion is reporting body stature on international visas, medical charts, and driver licenses. While North American systems record height in compound feet and inches (such as 5'10"), the World Health Organization (WHO), Schengen border authorities, and medical clinical trial protocols mandate metric recording in centimeters.
Why Rounding Shortcuts Cause Medical Discrepancies
A frequent shortcut is approximating 1 inch as 2.5 cm instead of 2.54 cm. Over an adult height of 70 inches (5'10″), this 0.04 cm difference compounds into an error of 2.8 centimeters (175 cm vs the correct 177.8 cm). In medical dosing calculations based on Body Surface Area (BSA) or Body Mass Index (BMI), an error of nearly 3 cm can skew pharmaceutical dosages.
Always compute centimeters using the exact formula: Total Inches × 2.54 or our automated calculator above. Check the companion Meters to Feet Converter when translating clinical trials published in metric notation.
Architecture, Interior Clearance & Ceiling Heights
In architectural drafting and building construction, imperial blueprints frequently clash with metric material specifications (such as European curtain walls, IKEA cabinetry, and imported HVAC ductwork). Understanding imperial clearance standards in centimeters prevents costly job-site re-framing:
Residential Ceiling Heights
A traditional 8-foot ceiling converts to 243.84 cm. Modern luxury developments featuring 9-foot and 10-foot ceilings correspond to 274.32 cm and 304.80 cm respectively.
Door Rough Openings
The standard 6-foot 8-inch interior door frame equals 80 inches or 203.20 cm. Commercial 7-foot doors equal 84 inches or 213.36 cm.
Wall Stud Framing Spacing
Standard 16-inch on-center (OC) wall studs equal 40.64 cm, while 24-inch OC advanced framing studs equal 60.96 cm.
Frequently Asked Questions (FAQ)
How many centimeters are in 1 foot?
There are exactly 30.48 centimeters in 1 international foot (1 ft = 12 in × 2.54 cm = 30.48 cm).
How tall is 5 feet 10 inches in cm?
5 feet 10 inches is exactly 177.80 centimeters. Computation: (5 × 12) + 10 = 70 inches; 70 × 2.54 = 177.8 cm.
How tall is 6 feet in cm?
6 feet equals exactly 182.88 centimeters (6 × 30.48 = 182.88 cm), which is approximately 1.83 meters.
What is the formula to convert feet to centimeters in Excel or Google Sheets?
In spreadsheet software, multiply cell A1 by 30.48 using =A1*30.48 or use the built-in unit conversion function: =CONVERT(A1, "ft", "cm").
How many centimeters is an 8-foot ceiling?
An 8-foot ceiling is exactly 243.84 centimeters (or 2.4384 meters), which is the standard minimum ceiling height in international residential building codes.
