How to calculate ft and inches?
Converting Feet and Inches to Centimeters
Converting measurements from feet and inches to centimeters is a common task that involves a simple, two-step process. First, combine the feet and inches into a single measurement of total inches. Then, convert that total into centimeters.
For an accurate conversion, it is crucial to use the standard international factor: one inch is equal to exactly 2.54 centimeters [3]. Using this precise value ensures your calculations are correct.
Manual Conversion Steps
To perform the conversion manually, follow these straightforward steps:
- Convert Feet to Inches: Multiply the number of feet by 12 (since there are 12 inches in a foot).
- Calculate Total Inches: Add any remaining inches to the result from the first step.
- Convert to Centimeters: Multiply the total number of inches by 2.54 to find the final measurement in centimeters.
Manual Calculation Example
Let’s convert a common height: 5 feet 9 inches to centimeters.
- Step 1: Convert feet to inches.
5 feet * 12 inches/foot = 60 inches - Step 2: Add remaining inches.
60 inches + 9 inches = 69 total inches - Step 3: Convert total inches to centimeters.
69 inches * 2.54 cm/inch = 175.26 cm
Therefore, 5 feet 9 inches is equal to 175.26 centimeters.
