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.
This free calculator turns the three dimensions you enter—length (ft), width (ft) and depth (in)—into three useful numbers. First it converts depth to feet, multiplies the three measurements to get cubic feet, then divides by 27 to show cubic yards. Finally it multiplies cubic yards by the industry‑standard 1.4 US tons per cubic yard to give an approximate weight. Knowing the volume in cubic yards helps you order the right amount of rock, while the ton estimate lets you budget for delivery costs. The cubic‑feet figure is handy for comparing against other material specs. All results appear instantly, so you can adjust dimensions on the fly and avoid costly over‑ or under‑ordering.
Pro tips
- Add 5‑10% extra for breakage and compaction.
- Round up to the nearest whole yard for ordering simplicity.
- Check local suppliers’ weight per yard; 1.4 tons is a typical average.
- Enter depth in whole inches; the calculator handles the conversion automatically.
Real-life examples
- A homeowner planning a new patio needs to know how much crushed stone to order.
- A landscaper estimating material for a garden retaining wall wants both volume and weight.
- A contractor sizing a driveway base wants quick numbers to include in a bid.
Case study
John entered his 12 ft × 8 ft × 4 in project and the calculator showed 0.89 yd³ (≈1.2 tons). He ordered 1 yard, saved $150 on excess material, and finished on schedule.
