1. What is the Square Foot Calculator?

The Square Foot Calculator converts measurements in inches to square feet, which is useful for various applications including flooring, painting, and material estimation projects.

2. How Does the Calculator Work?

The calculator uses the square foot formula:

Where:

• \( SF \) — Square feet
• \( L \) — Length in inches
• \( W \) — Width in inches
• \( 144 \) — Conversion factor (1 square foot = 144 square inches)

Explanation: The equation calculates area in square inches then converts to square feet by dividing by 144.

3. Importance of Square Foot Calculation

Details: Accurate area calculation is essential for material estimation, cost calculation, and project planning in construction, interior design, and landscaping projects.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 144?
A: Because 1 square foot equals 12 inches × 12 inches = 144 square inches.

Q2: Can I use this for circular areas?
A: No, this calculator is designed for rectangular areas. For circles, use π × radius² (in inches) / 144.

Q3: What about irregular shapes?
A: For irregular shapes, break them down into smaller rectangles, calculate each separately, then sum the results.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your measurements.

Q5: Can I calculate square yards instead?
A: Yes, divide the square footage by 9 (since 1 square yard = 9 square feet).
