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.

What this calculator does

It converts the dimensions you provide (length × width × depth) into three practical measures: cubic yards, tons (approx.), and cubic feet. Knowing the volume in cubic yards lets you order the right amount of topsoil, while the ton estimate helps you compare pricing that’s often listed by weight.

Why the result matters

  • Cubic yards is the standard unit suppliers use.
  • Tons uses the constant 1.3 US tons per cubic yard, so you see the weight you’ll handle.
  • Cubic feet helps you visualize the space on‑site.

How to read it

If you input 10 ft × 10 ft × 6 in, the calculator shows 1.85 yd³, ≈2.4 tons, and 50 ft³. Use these numbers to place an accurate order and avoid over‑ or under‑buying.

Pro tips

  • Add a 5‑10% waste allowance for compaction and settling.
  • Round up to the nearest whole yard when ordering; suppliers rarely sell fractions.
  • Order a little extra if you plan to spread the soil in multiple passes.
  • Double‑check depth conversion (inches ÷ 12) to avoid mis‑calculations.

Real-life examples

  • A homeowner preparing a new garden bed needs the exact topsoil amount to fill a 12 ft × 8 ft area 4 in deep.
  • A landscaper estimating material for a residential lawn renovation wants both volume and weight for budgeting.
  • A contractor ordering bulk topsoil for a small park renovation needs the cubic‑yard figure to get a bulk discount.

Case study

Jane wanted to fill a 15 ft × 10 ft patio base 3 in deep. Using the estimator she saw she needed 1.39 yd³ (~1.8 tons). She ordered 2 yd³, avoided a costly shortfall, and finished on schedule.

Frequently asked questions

How do I convert depth from inches to feet?
Divide the inches by 12; the calculator does this automatically.
Why is the ton estimate only approximate?
It uses a standard density of 1.3 US tons per cubic yard, which is typical for most topsoil mixes.
Can I use the calculator for sand or gravel?
The volume numbers are correct, but the weight constant differs, so adjust the ton estimate accordingly.
Do I need to account for compaction?
Add a 5‑10% waste factor to the cubic‑yard result to cover compaction and settling.
Is the calculator free to use?
Yes, it’s completely free and requires no sign‑up.
