Square Feet Formula:
| From: | To: |
Square foot calculation is a fundamental measurement used to determine the area of a two-dimensional space. It is commonly used in construction, real estate, interior design, and landscaping to measure floor space, wall areas, and other surfaces.
The calculator uses the simple area formula:
Where:
Explanation: The formula multiplies the length by the width to calculate the total area in square feet. This works for any rectangular or square-shaped area.
Details: Accurate square footage calculations are essential for determining material quantities, pricing projects, space planning, property valuation, and compliance with building codes and regulations.
Tips: Enter the length and width measurements in feet. Both values must be positive numbers. The calculator will automatically compute the square footage when you click calculate.
Q1: Can I use this calculator for irregular shapes?
A: This calculator is designed for rectangular areas. For irregular shapes, you may need to break the area into multiple rectangles, calculate each separately, then sum the results.
Q2: What's the difference between square feet and square meters?
A: Square feet is the imperial unit of area, while square meters is the metric unit. 1 square meter equals approximately 10.764 square feet.
Q3: How accurate should my measurements be?
A: For most applications, measuring to the nearest inch or centimeter provides sufficient accuracy. For precise calculations (like material ordering), measure to the nearest 1/8 inch or 3 mm.
Q4: Can I calculate square footage from inches or yards?
A: Yes, but you must convert all measurements to the same unit first. Convert inches to feet by dividing by 12, or yards to feet by multiplying by 3.
Q5: Why is square footage important in real estate?
A: Square footage is a key factor in property valuation, pricing comparisons, and determining usable space. It helps buyers, sellers, and appraisers assess property value accurately.
