1. What is the Topsoil Calculation?

The topsoil calculation determines how much topsoil (in cubic yards) you need to cover a specific area to a certain depth. This is essential for gardening, landscaping, and construction projects.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( Sq ft \) — Area in square feet
• \( Depth ft \) — Desired depth in feet
• 27 — Conversion factor (1 cubic yard = 27 cubic feet)

Explanation: The formula converts square footage at a given depth into cubic yards, the standard measurement for bulk topsoil.

3. Importance of Accurate Topsoil Calculation

Details: Proper calculation ensures you order the right amount of topsoil - not too little that your project is incomplete, nor too much that you waste money on excess material.

4. Using the Calculator

Tips: Measure your area accurately in square feet. Common depth recommendations: 6-12 inches for lawns, 12-18 inches for gardens. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert inches to feet for depth?
A: Divide inches by 12. For example, 6 inches = 0.5 feet.

Q2: What if my area isn't a perfect rectangle?
A: Break irregular shapes into rectangles, calculate each separately, then sum the results.

Q3: How much does a cubic yard of topsoil weigh?
A: Approximately 1,000-1,500 lbs depending on moisture content and composition.

Q4: Should I order extra topsoil?
A: It's common to add 10-15% to account for settling and compaction.

Q5: How do I measure an irregularly shaped area?
A: Use the "average length × average width" method for rough estimates, or divide into smaller regular shapes.
