Square Foot Formula:
| From: | To: |
Square foot calculation is a measurement of area used primarily in the United States and other countries that use the imperial system. It represents the area of a square with sides measuring one foot in length.
The calculator uses the simple area formula:
Where:
Unit Conversion: The calculator automatically converts inches and centimeters to feet before performing the calculation:
Details: Square footage calculation is essential in real estate, construction, interior design, landscaping, and many other fields where area measurement is required for planning, pricing, or material estimation.
Tips: Enter the length and width measurements, then select the appropriate unit for each (inches, feet, or centimeters). The calculator will automatically convert to square feet and display the result.
Q1: Can I mix different units for length and width?
A: Yes, the calculator handles different units for length and width and converts both to feet before calculation.
Q2: How accurate is the conversion from metric to imperial?
A: The conversion uses the standard conversion factors (1 inch = 2.54 cm, 1 foot = 30.48 cm) and provides results rounded to two decimal places.
Q3: What if I have measurements in yards or meters?
A: For yards, convert to feet first (1 yard = 3 feet). For meters, convert to centimeters first (1 meter = 100 cm) then use the cm option.
Q4: Can this calculator handle irregular shapes?
A: No, this calculator is designed for rectangular areas only. For irregular shapes, you would need to break the area into rectangular sections and calculate each separately.
Q5: How do I calculate square footage for a room with multiple sections?
A: Calculate each rectangular section separately using this calculator, then add all the results together for the total square footage.
