1. What is Square Feet Calculation?

Square feet calculation converts measurements in inches to square feet, which is a standard unit of area measurement commonly used in construction, real estate, and interior design.

2. How Does the Calculator Work?

The calculator uses the square feet formula:

Where:

• \( SF \) — Square feet
• \( L \) — Length in inches
• \( W \) — Width in inches
• 144 — Conversion factor (12 inches × 12 inches)

Explanation: Since 1 square foot equals 144 square inches (12 inches × 12 inches), we divide the product of length and width by 144 to convert from square inches to square feet.

3. Importance of Square Feet Calculation

Details: Accurate area calculation is essential for determining material quantities, estimating costs, planning spaces, and complying with building codes and regulations.

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 1 square foot equals 144 square inches (12 inches × 12 inches).

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

Q3: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your measurements.

Q4: What if I have measurements in feet and inches?
A: Convert all measurements to inches first (1 foot = 12 inches), then use the calculator.

Q5: Can this be used for three-dimensional calculations?
A: No, this calculates area only. For volume, you would need a third dimension (height/depth).
