Square Footage Formula:
| From: | To: |
Square footage calculation is the process of determining the area of a space in square feet. When working with measurements in inches, we convert to square feet by dividing the product of length and width by 144 (since 1 square foot = 144 square inches).
The calculator uses the square footage formula:
Where:
Explanation: This formula converts area measured in square inches to square feet, which is the standard unit for measuring floor space, property area, and other large surfaces.
Details: Accurate square footage calculation is essential for construction projects, real estate valuation, flooring installation, painting estimates, and many other applications where area measurement is required.
Tips: Enter both length and width measurements in inches. Ensure measurements are accurate and in the same unit (inches). The calculator will automatically convert to square feet.
Q1: Why divide by 144?
A: There are 144 square inches in one square foot (12 inches × 12 inches = 144 square inches).
Q2: Can I use this for irregular shapes?
A: No, this calculator is designed for rectangular or square areas. For irregular shapes, you would need to break the area into smaller rectangular sections.
Q3: What if I have measurements in feet and inches?
A: Convert all measurements to inches first (1 foot = 12 inches), then use the calculator.
Q4: How accurate should my measurements be?
A: For most applications, measuring to the nearest 1/4 inch is sufficient, but precision work may require more accurate measurements.
Q5: Can this be used for three-dimensional calculations?
A: No, this calculator is for two-dimensional area only. For volume calculations, you would need to incorporate height/depth measurements.
