Square Yards Formula:
| From: | To: |
Square yards calculation is used to determine the area of a space in square yards, particularly useful for concrete projects where materials are often measured and priced per square yard.
The calculator uses the square yards formula:
Where:
Explanation: Since 1 square yard equals 9 square feet, we divide the total square footage by 9 to get square yards.
Details: Accurate square yards calculation is essential for concrete projects to determine the correct amount of materials needed, estimate costs accurately, and avoid over-ordering or under-ordering concrete.
Tips: Enter length and width measurements in feet. Both values must be positive numbers. The calculator will automatically convert square feet to square yards.
Q1: Why divide by 9 to get square yards?
A: Because 1 square yard equals 9 square feet (3 feet × 3 feet), so dividing square footage by 9 converts it to square yards.
Q2: What if I have measurements in different units?
A: Convert all measurements to feet first. For inches, divide by 12; for yards, multiply by 3; for meters, multiply by 3.28084.
Q3: How much extra concrete should I order?
A: It's recommended to order 5-10% extra concrete to account for spillage, uneven surfaces, and measurement errors.
Q4: Can this calculator be used for irregular shapes?
A: This calculator is for rectangular areas only. For irregular shapes, break the area into smaller rectangles, calculate each separately, then sum the results.
Q5: What's the difference between square yards and cubic yards?
A: Square yards measure area (length × width), while cubic yards measure volume (length × width × depth). For concrete thickness, you'll need cubic yards.
