Free Cubic Yard Calculator Online
Convert dimensions to cubic yards for bulk material ordering
The Cubic Yard Calculator converts length, width, and depth measurements into cubic yards — the standard unit for ordering bulk materials like concrete, topsoil, mulch, fill dirt, and gravel in the United States. Landscapers, contractors, and homeowners use it to match project dimensions to delivery truck loads and avoid under- or over-ordering.
Frequently Asked Questions
About the Cubic Yard Calculator
One cubic yard equals 27 cubic feet — a conversion that seems simple but trips up anyone mixing feet and inches for length and depth. Entering depth in inches without converting to feet first produces an answer off by a factor of 12, which is a common and expensive mistake when ordering truckloads of material.
This calculator handles the inch-to-feet conversion internally, accepting length and width in feet, yards, or metres and depth in inches or centimetres, then outputting the final volume in cubic yards, cubic feet, and cubic metres simultaneously. It also estimates the weight of common materials at that volume for truck capacity planning.
Landscaping projects — topsoil for lawns, mulch for garden beds, fill dirt for levelling — are typically quoted in cubic yards. Ready-mix concrete trucks carry 8–10 cubic yards; a typical landscaping delivery truck carries 1–3 cubic yards. Knowing your required volume in cubic yards first makes it straightforward to plan how many deliveries you need.
When Should You Use This?
The Cubic Yard Calculator is ideally suited for contractors, builders, architects, and DIY enthusiasts who need to perform quick, accurate calculations related to general calculations. Use this tool when you need to verify figures, compare different scenarios, or get a precise answer without manual computation errors.
What Does The Result Mean?
The calculated output provides an instant, accurate resolution to your input parameters. You can use these results directly for your planning, assignments, or professional tasks, knowing they are based on standardized formulas.
Example Calculation
Cubic yards of topsoil needed for a raised garden bed
📥 Inputs
- Length: 12 feet
- Width: 4 feet
- Depth: 8 inches (0.667 feet)
🔢 Calculation Steps
- 1Volume in cubic feet: 12 × 4 × 0.667 = 32 ft³
- 2Convert to cubic yards: 32 ÷ 27 = 1.185 yd³
- 3Add 10% for settling: 1.185 × 1.10 = 1.30 yd³
- 41 cubic yard of topsoil ≈ 2,000 lbs (≈ 900 kg)
- 5Approximate weight: 1.30 × 2,000 = 2,600 lbs
Limitations of this Calculator
