The key principle in converting feet to inches is understanding the conversion factor:
$1 \text{ foot} = 12 \text{ inches}$
To convert feet to inches, you simply multiply the number of feet by 12.
๐ฃ Step-by-Step Conversion Process
- ๐ Identify the Number of Feet: Determine the quantity you want to convert from feet to inches.
- ๐ข Multiply by the Conversion Factor: Multiply the number of feet by 12 (since there are 12 inches in a foot).
- โ
Calculate the Result: Perform the multiplication to get the equivalent measurement in inches.
โ๏ธ Example Problems
Let's work through some examples:
Example 1: Convert 5 feet to inches.
$5 \text{ feet} \times 12 \text{ inches/foot} = 60 \text{ inches}$
Example 2: Convert 2.5 feet to inches.
$2.5 \text{ feet} \times 12 \text{ inches/foot} = 30 \text{ inches}$
Example 3: Convert 10 feet to inches.
$10 \text{ feet} \times 12 \text{ inches/foot} = 120 \text{ inches}$
