How to Convert Feet and Inches to Centimeters
In the US and UK, height and length are often written as feet plus inches (for example, 5′9″). Most of the world uses centimeters (cm) from the metric system. To convert, multiply the total number of inches by 2.54, because one inch equals exactly 2.54 centimeters.
Example: 5 feet 9 inches = (5 × 12) + 9 = 69 inches → 69 × 2.54 = 175.26 cm. This free feet and inches to cm converter does that math for you and also converts cm back to ft + in for medical forms, travel, fitness apps, and school science units.
