Square Feet to Cubic Yards Formula:
| From: | To: |
The square feet to cubic yards conversion calculates the volume of material needed when you know the area in square feet and the depth in feet. This is commonly used in construction, landscaping, and materials estimation.
The calculator uses the formula:
Where:
Explanation: The formula converts square footage at a given depth into cubic yards by multiplying area by depth to get cubic feet, then dividing by 27 to convert to cubic yards.
Details: Accurate volume calculation is essential for estimating materials like concrete, soil, mulch, gravel, and other bulk materials. It helps prevent over-ordering or under-ordering materials for projects.
Tips: Enter the area in square feet and the depth in feet. Both values must be positive numbers. The calculator will provide the volume in cubic yards.
Q1: Why divide by 27 in the formula?
A: Because there are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet = 27 cubic feet).
Q2: Can I use this for irregular shapes?
A: This calculator works for rectangular or square areas. For irregular shapes, you may need to calculate the area first or use more complex volume calculations.
Q3: What if my depth is in inches instead of feet?
A: Convert inches to feet first (divide inches by 12) before using the calculator.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the accuracy of your area and depth measurements.
Q5: What materials is this calculator useful for?
A: This calculator is useful for estimating concrete, topsoil, mulch, gravel, sand, and other bulk materials sold by cubic yards.
