1. What is Square Feet Calculation?

Square footage calculation converts length and width measurements in inches to area in square feet. This is commonly used in construction, flooring, and interior design to determine material quantities.

2. How Does the Calculator Work?

The calculator uses the square feet formula:

Where:

• Length — Measurement in inches
• Width — Measurement in inches
• 144 — Conversion factor (1 sq ft = 144 sq inches)

Explanation: The formula first calculates area in square inches, then converts to square feet by dividing by 144 (since 1 foot = 12 inches, 1 sq ft = 12×12 = 144 sq inches).

3. Importance of Square Footage

Details: Accurate square footage calculation is essential for purchasing materials, estimating costs, and planning spaces in construction and interior design projects.

4. Using the Calculator

Tips: Enter length and width in inches. Both values must be positive numbers. The calculator will automatically convert to square feet.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 144?
A: Because there are 144 square inches in one square foot (12 inches × 12 inches = 144 sq in).

Q2: Can I use this for circular areas?
A: No, this is for rectangular areas. For circles, use πr²/144 where r is radius in inches.

Q3: How accurate should my measurements be?
A: For most projects, measuring to the nearest 1/4 inch is sufficient, but precision depends on your needs.

Q4: What if my area isn't a perfect rectangle?
A: Break irregular shapes into rectangular sections, calculate each separately, then sum the results.

Q5: How do I convert square feet back to inches?
A: Multiply square feet by 144 to get square inches, but you won't get the original length/width unless it's a square.
