How to use it
- Enter length in feet
- Enter width in feet
- Enter depth in inches
- Read the three results
What this calculator does
It converts the dimensions you input (length, width, depth) into three practical measures: cubic yards, tons (approx.), and cubic feet. Knowing the yardage tells you how many bulk bags or dump‑truck loads to order. The ton estimate uses the industry standard of 1.4 US tons per cubic yard, so you can compare material costs that are often quoted by weight. Cubic feet is useful for small‑scale projects or when you need to fill a confined space.
How to read the output
- Cubic yards – the primary unit for bulk ordering.
- Tons (approx.) – multiply cubic yards by 1.4; this is the weight you’ll see on supplier invoices.
- Cubic feet – total volume for quick visual checks. Use these numbers to budget, avoid over‑ordering, and keep your project on schedule.
Pro tips
- Add 5‑10% extra for compaction and spillage
- Round up to the nearest whole yard for easier ordering
- Check local suppliers’ weight per yard; 1.4 tons is an average
- Measure depth from the finished grade, not the sub‑base
Real-life examples
- A homeowner planning a new driveway wants to know how much pea gravel to order
- A landscaper estimating material for a garden path replacement
- A DIY enthusiast budgeting for a backyard fire pit base
Case study
Maria entered her patio size (12 ft × 8 ft × 4 in) and got 0.9 cubic yards, 1.3 tons, and 24 cubic feet, letting her order exactly one bulk bag and stay within budget.
