How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, cubic feet, and tons.
What it does – The Gravel Tonnage Calculator converts the dimensions you provide (length ft, width ft, depth in) into three useful measures: cubic yards, cubic feet, and an estimated tonnage. Why it matters – Knowing cubic yards tells you how many loads a supplier will charge, cubic feet helps when ordering from a bulk bin, and tons let you compare material costs that are priced by weight. How to read the results – The cubic‑yard figure is the primary volume; multiply by 1.4 to see the ton estimate (the tool does this for you). The cubic‑foot number is simply the volume in a more familiar unit. Use these numbers to order the right amount of gravel and avoid costly over‑or under‑ordering. You can also save the calculation for future projects or share it with contractors. Because the weight conversion uses a standard 1.4 US tons per cubic yard, the ton estimate is reliable for most common gravels. If your site has uneven terrain, add a small percentage to the volume to cover compaction. The calculator works instantly in any browser, so you can get the numbers on site or on the go.
Pro tips
- Add 5‑10% extra for compaction and uneven ground.
- Round up to the nearest whole cubic yard to simplify ordering.
- Compare supplier prices by tons and by cubic yards to find the best deal.
- Double‑check depth conversion from inches to feet before entering data.
Real-life examples
- A homeowner planning a new driveway needs to know how much gravel to order.
- A landscaper estimating material for a garden path wants both volume and weight.
- A contractor budgeting for a parking lot base must quote total tons of aggregate.
Case study
Maria wanted a 10 × 12 ft patio with a 4‑inch gravel base. Using the calculator she saw she needed 1.33 cubic yards, which the tool translated to 1.86 tons, allowing her to order the exact amount and avoid a costly over‑order.
