What it does – The Omni Gravel Calculator turns the dimensions of your area (length, width, depth) into three useful measures: cubic yards, tons, and cubic feet. Knowing the exact volume helps you order the right amount of material, avoid costly over‑orders, and keep your project on schedule. Why it matters – Gravel is sold by the cubic yard, but many contractors think in tons; this tool bridges that gap with the industry‑standard 1.4 tons per cubic yard. How to read the results – Cubic yards is the primary quantity for ordering, tons gives you a weight estimate for transport, and cubic feet lets you double‑check calculations or plan smaller jobs. All results appear instantly after you input the three dimensions, so you can make decisions on the spot.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest whole cubic yard to ensure enough material.
  • Order by the ton if the supplier quotes weight, using 1.4 tons per cubic yard.
  • Double‑check depth measurements; a 1‑inch error can change volume significantly.

Real-life examples

  • Homeowner installing a new driveway and wants the exact gravel amount.
  • Landscaper planning a garden path and needs both volume and weight for delivery quotes.
  • DIY enthusiast building a raised patio and wants to avoid ordering too much or too little gravel.

Case study

Sarah needed 2 cubic yards of gravel for a backyard walkway. Using the calculator, she entered 10 ft × 4 ft × 3 in and got 2 cubic yards (2.8 tons). She ordered exactly that amount, saving $45 on excess material.

What if my depth is in centimeters?
Convert centimeters to inches (1 cm ≈ 0.39 in) before entering.
Do I need to include a waste factor?
Add 5‑10% to the cubic yards result for compaction and spillage.
Is the result in US tons?
