Square Feet Formula:
| From: | To: |
Square feet (sq ft) is a unit of area measurement commonly used in the United States and other countries that follow the imperial system. It represents the area of a square with sides measuring one foot each.
The formula for calculating square feet is:
Where:
Explanation: Multiply the length measurement by the width measurement to get the total area in square feet. Both measurements must be in the same unit (feet).
Details: Square footage calculation is essential for various applications including real estate, construction, interior design, landscaping, and flooring installation. It helps determine the size of spaces, material requirements, and property values.
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 different units for length and width?
A: No, both measurements must be in the same unit. If you have measurements in different units, convert them both to feet first before calculating.
Q2: How do I calculate square feet for irregular shapes?
A: For irregular shapes, divide the area into regular shapes (rectangles, triangles), calculate each area separately, then sum them up.
Q3: What's the difference between square feet and square meters?
A: Square feet is an imperial unit while square meters is a metric unit. 1 square meter equals approximately 10.764 square feet.
Q4: How accurate should my measurements be?
A: For most practical purposes, measurements to the nearest inch or centimeter are sufficient. For precise calculations, use decimal feet.
Q5: Can this calculator be used for three-dimensional measurements?
A: No, this calculator is for two-dimensional area calculations. For volume calculations, you would need to multiply area by height.
