Topsoil Calculation Formula:
From: | To: |
The Topsoil Calculator estimates the volume of topsoil needed in cubic yards based on the area's length, width, and desired depth. It's essential for gardening, landscaping, and construction projects.
The calculator uses the formula:
Where:
Explanation: The formula calculates cubic feet first, then converts to cubic yards by dividing by 27.
Details: Accurate topsoil calculation helps in budgeting, prevents over-ordering, and ensures proper coverage for your project.
Tips: Measure the area's length and width in feet. Determine desired depth (typically 6-12 inches for gardens). Enter all values as positive numbers.
Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard. The division converts cubic feet to cubic yards.
Q2: What's the typical depth for topsoil?
A: For lawns, 4-6 inches is common. For gardens, 6-12 inches is recommended depending on plants.
Q3: How do I measure irregular areas?
A: Break into rectangles, calculate each separately, then sum the volumes.
Q4: Does this account for soil compaction?
A: No, you may need 10-15% extra volume to account for settling and compaction.
Q5: How many bags is this equivalent to?
A: 1 cubic yard = about 40-50 1.5 cubic foot bags. Check bag sizes as they vary.
