What is an Inch?
- An inch is a unit of length in the Imperial system.
- It is widely used in the United States, the United Kingdom, and other countries that employ the Imperial or customary measurement systems.
- One inch is equivalent to 1/12 of a foot.

Converting Inches to Feet: The Basic Method
The conversion process from inches to feet involves understanding the relationship between these units:
1 foot = 12 inches
To convert inches to feet, you divide the number of inches by 12:
\[ \text{Feet} = \frac{\text{Inches}}{12} \]
Applying this to 90 inches:
\[ \text{Feet} = \frac{90}{12} = 7.5 \]
Thus, 90 inches equals 7.5 feet.

Step-by-step Conversion Process
Let's walk through the process more thoroughly:
1. Identify the measurement in inches: In this case, 90 inches.
2. Recall the conversion factor: 1 foot = 12 inches.
3. Divide the inches by 12:
\[
90 \div 12 = 7.5
\]
4. Result interpretation: The result, 7.5, indicates that 90 inches is 7 full feet and a half-foot (which is 6 inches).
Summary: 90 inches = 7 feet and 6 inches.

Expressing 90 Inches in Feet and Inches
While the decimal form (7.5 feet) is useful for calculations, sometimes it's more practical to express measurements in feet and inches separately, especially in construction or tailoring.
Steps to convert 90 inches into feet and inches:
1. Divide the total inches by 12:
\[
90 \div 12 = 7 \text{ R } 6
\]
- The quotient (7) is the number of feet.
- The remainder (6) is the number of inches.
2. Final measurement: 7 feet 6 inches.
This format is often more intuitive when measuring real-world objects or spaces.
