What is the Feet+Inches to Centimeters Converter?
The Feet and Inches to Centimeters (cm) converter is the most common tool used to translate American heights (e.g., 5'11") into the global metric standard (cm) used on international medical forms and ID cards.
How It Works (Formula)
The calculator executes a two-step process. First, it flattens the input into total inches by multiplying the feet by 12 and adding the remaining inches. It then multiplies that combined inch count by exactly 2.54 to find the metric equivalent.
$$ L_{(\text{cm})} = ((L_{(\text{ft})} \times 12) + L_{(\text{in})}) \times 2.54 $$
The flattening multiplication formula mapping US heights to metric.
How to Use It
Input the feet in the first field and the inches in the second field (e.g., 5 feet, 10 inches). The tool will combine them, apply the 2.54 multiplier, and instantly output the total length in Centimeters (cm). A 5'10" person is exactly 177.8 cm.
