How to Convert Feet and Inches to Centimeters: Formula, Steps & Common Examples
What is Feet to Centimeter Conversion?
Feet to centimeter conversion is the process of changing a measurement given in feet (and optionally inches) into its equivalent value in centimeters (cm), which is a metric unit of length. This conversion is essential because feet and inches are commonly used in countries like the United States and the United Kingdom, while centimeters are part of the metric system used in most of the world for science, education, health, and daily measurements.
Everyday examples of this conversion include calculating personal height (e.g., 5'7" to cm), converting construction or architectural dimensions, fitness and sports records, school homework, and travel documents. Centimeters provide a higher degree of precision, making them very useful in scientific and academic contexts.
Formula to Convert Feet to CM
Converting feet to centimeters uses a simple formula based on the fact that 1 foot is exactly 30.48 centimeters and 1 inch is 2.54 centimeters. The formula is:
Centimeters (cm) = (Feet × 12 + Inches) × 2.54
Stepwise:
- Multiply the number of feet by 12 to get inches
- Add the number of extra inches (if any)
- Multiply the total inches by 2.54 to find the value in centimeters
Example: 5 feet 10 inches to cm
Total inches = (5 × 12) + 10 = 60 + 10 = 70 inches
Centimeters = 70 × 2.54 = 177.8 cm
