Square Footage Formula:
From: | To: |
Square footage calculation converts measurements in inches to square feet, which is the standard unit for measuring area in many applications, particularly in construction, real estate, and interior design.
The calculator uses the formula:
Where:
Explanation: This formula converts the area from square inches to square feet by dividing by 144, as there are 144 square inches in one square foot.
Details: Accurate square footage calculation is essential for determining material quantities, pricing projects, space planning, and property valuation.
Tips: Enter length and width measurements in inches. All values must be valid positive numbers. The calculator will automatically convert to square feet.
Q1: Why divide by 144?
A: Because 1 foot equals 12 inches, so 1 square foot equals 12 × 12 = 144 square inches.
Q2: Can I use this for irregular shapes?
A: No, this formula only works for rectangular or square areas. Irregular shapes require more complex calculations.
Q3: 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.
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 calculator be used for three-dimensional measurements?
A: No, this calculator is specifically for calculating area (2D). Volume calculations require additional dimensions.
