Square Footage Formula:
| From: | To: |
Square footage calculation is a method to determine the area of a space in square feet. This calculator specifically handles measurements in inches and converts them to square feet using the standard conversion factor.
The calculator uses the square footage formula:
Where:
Explanation: Since there are 144 square inches in one square foot, we divide the product of length and width by 144 to convert from square inches to square feet.
Details: Accurate square footage calculation is essential for construction projects, flooring installation, painting estimates, real estate valuation, and many other applications where area measurement is required.
Tips: Enter length and width measurements in inches. Both values must be positive numbers. The calculator will automatically convert the result to square feet.
Q1: Why divide by 144 in the formula?
A: Because there are 144 square inches in one square foot (12 inches × 12 inches = 144 square inches).
Q2: Can I use this calculator for measurements in feet?
A: No, this calculator is specifically designed for inch measurements. For feet measurements, simply multiply length by width without dividing by 144.
Q3: How accurate is this calculation?
A: The calculation is mathematically precise. The accuracy of your result depends on the precision of your input measurements.
Q4: Can I calculate square footage for irregular shapes?
A: No, this calculator is designed for rectangular areas only. For irregular shapes, you would need to break the area down into smaller rectangles.
Q5: What if I have measurements in both feet and inches?
A: Convert all measurements to inches first (1 foot = 12 inches), then use the calculator.
