Square Footage Formula:
From: | To: |
Square footage calculation measures the area of a space in square feet. It's essential for construction, real estate, flooring, painting, and many other applications where accurate area measurements are required.
The calculator uses the area formula:
Where:
Explanation: The calculator converts inches to decimal feet (dividing by 12) and then multiplies the total length by total width to get the area in square feet.
Details: Accurate square footage calculations are crucial for material estimation, cost calculations, space planning, and compliance with building codes and regulations.
Tips: Enter feet and inches separately for both length and width. Inches must be between 0-11. All values must be non-negative numbers.
Q1: Why calculate with feet and inches separately?
A: This approach allows for precise measurements using standard imperial units without converting everything to decimal feet first.
Q2: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your input measurements.
Q3: Can I use this for irregular shapes?
A: This calculator is for rectangular areas only. For irregular shapes, you would need to break the area into smaller rectangles or use other methods.
Q4: What about fractional inches?
A: This calculator uses whole inches. For fractional inches, you would need to convert fractions to decimal inches first.
Q5: How do I convert square feet to other units?
A: 1 square foot = 144 square inches = 0.092903 square meters. Multiply by these conversion factors as needed.
