How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Click Calculate to see cubic yards, tons, and cubic feet.
What it does – The calculator converts the dimensions of a rock fill area (length, width, depth) into three useful measures: cubic yards, cubic feet, and an approximate weight in US tons. Knowing the exact volume prevents ordering too little material, which can delay a project, or too much, which wastes money. Why it matters – Contractors and DIY homeowners use cubic yards to order deliveries, cubic feet for on‑site measurements, and tons to understand load limits and shipping costs. How to read the results – Cubic yards is the standard unit for bulk rock orders; multiply it by 1.4 to see the estimated tons. Cubic feet shows the same volume in a smaller unit, handy for comparing with existing space. All results appear instantly after you hit the button.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up the cubic yards to the nearest 0.1 for ordering.
- Verify the depth is measured in inches before converting.
- Compare the ton estimate with supplier load limits to avoid over‑weight deliveries.
Real-life examples
- A homeowner preparing a 12 ft × 15 ft patio with a 4‑inch sand base.
- A contractor estimating rock fill for a 30 ft × 40 ft drainage trench 6 in deep.
- A landscape designer calculating material for a 20 ft × 25 ft garden path 3 in thick.
Case study
Jane needed rock for a 10 ft × 12 ft area 6 in deep. Using the calculator she saw she required 2.22 yd³, about 3.1 tons. She ordered 2.3 yd³, saved $200, and the project stayed on schedule.
