Square Feet Formula:
| From: | To: |
Square feet calculation is a fundamental measurement used to determine the area of a two-dimensional space. It's calculated by multiplying the length by the width of an area, both measured in feet.
The calculator uses the simple area formula:
Where:
Explanation: This formula calculates the area of rectangular or square spaces by multiplying the two perpendicular dimensions.
Details: Square footage calculation is essential for construction, real estate, flooring installation, painting estimates, landscaping, and any project that requires area measurement. Accurate calculations help with material estimation and cost planning.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). For irregular shapes, break them down into rectangular sections and calculate each separately.
Q1: Can I use this calculator for non-rectangular areas?
A: This calculator is designed for rectangular areas. For irregular shapes, divide the area into rectangular sections, calculate each separately, then sum the results.
Q2: How do I convert other units to feet?
A: Convert all measurements to feet before calculating. For inches, divide by 12. For yards, multiply by 3. For meters, multiply by 3.28084.
Q3: What's the difference between square feet and feet?
A: Feet measure length (one dimension), while square feet measure area (two dimensions - length × width).
Q4: How accurate should my measurements be?
A: For most purposes, measurements to the nearest 1/4 foot (3 inches) are sufficient. For precise work, measure to the nearest inch or centimeter.
Q5: Can I calculate square feet for circular areas?
A: No, this calculator is for rectangular areas. For circles, use the formula: π × radius² (with radius in feet).
