How to use it

  1. Enter the length in feet.
  2. Enter the width in feet.
  3. Enter the depth in inches.
  4. Read the cubic yards, tons, and cubic feet results.

This Online Gravel Calculator turns your project dimensions into three practical measures: cubic yards, tons (approx), and cubic feet. You input length, width, and depth, and the tool instantly converts inches to feet, multiplies to get volume in cubic feet, then divides by 27 for cubic yards. Because gravel weighs about 1.4 US tons per cubic yard, the calculator multiplies cubic yards by that factor to give a quick weight estimate. Knowing cubic yards helps you order the right amount of material, while tons let you compare shipping options. Cubic feet is useful for smaller jobs or when mixing with other fill. The results are displayed side‑by‑side so you can see exactly what you’ll need before you call a supplier.

Pro tips

  • Add 5‑10% extra for compaction and spillage.
  • Round up to the nearest whole yard to avoid short‑orders.
  • Check supplier minimum order sizes before finalizing.
  • Verify depth is measured from the finished grade, not the sub‑base.

Real-life examples

  • A homeowner plans a new driveway and needs to know how many yards of gravel to order.
  • A landscaper estimates material for a garden path to give a client a precise quote.
  • A DIY enthusiast calculates fill for a backyard patio to avoid over‑buying.

Case study

Jenna entered a 12 ft × 8 ft area at 4 in depth, got 1.4 cubic yards and 2 tons, ordered that amount, and completed her patio without leftover material or extra trips.

Frequently asked questions

How do I convert the calculator’s cubic yards to tons?
Multiply the cubic yards by 1.4 US tons per cubic yard; the tool does this automatically.
Why does the calculator use 1.4 tons per cubic yard?
1.4 tons is the industry‑standard average weight for typical gravel.
Can I use the calculator for sand or mulch?
The volume conversion works, but use the specific weight factor for those materials.
Do I need to account for compaction?
Yes, add 5‑10% extra volume to cover settling and spillage.
Is the result in US or metric units?
All outputs are in US customary units: cubic yards, tons, and cubic feet.
