The primary principle in converting inches to feet is understanding the relationship: 1 foot = 12 inches. Therefore, converting inches to feet involves dividing the number of inches by 12.



Step-by-Step Conversion of 18 Inches into Feet




  1. Identify the total inches: 18 inches.

  2. Divide the total inches by 12 to convert to feet: 18 ÷ 12.

  3. Calculate the quotient: 1.5.

  4. Interpret the result: 1.5 feet.



Thus, 18 inches is equal to 1.5 feet.



Expressing the Conversion in Different Formats



Decimal Format



The decimal format is typically used for precise measurements. As shown above, 18 inches = 1.5 ft.



Fractional Format



Sometimes, measurements are expressed as fractions, especially in carpentry or tailoring. To express 1.5 feet in fractions:




  • Since 0.5 feet equals 6 inches (because 0.5 × 12 inches = 6 inches),

  • 1.5 feet = 1 foot + 6 inches,

  • or as a mixed number: 1 ½ feet.



Additional Conversion Examples



Converting Other Inches to Feet



Here are some common conversions to illustrate the process:




  • 6 inches = 0.5 feet (6 ÷ 12)

  • 24 inches = 2 feet (24 ÷ 12)

  • 36 inches = 3 feet (36 ÷ 12)

  • 48 inches = 4 feet (48 ÷ 12)



Converting Feet to Inches



To convert from feet to inches, multiply the number of feet by 12. For example:




  • 2 feet = 24 inches (2 × 12)

  • 3.5 feet = 42 inches (3.5 × 12)



Practical Applications of Inches and Feet Conversion
