How to use it

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

What it does – you enter length (ft), width (ft) and depth (in). The calculator converts depth to feet, multiplies to get cubic feet, then divides by 27 for cubic yards and multiplies by 1.3 to estimate tons. Why it matters – knowing volume helps you order the right amount of fill, avoid overpaying, and plan truck loads. Reading the results – cubic yards is the standard ordering unit, tons gives a weight estimate for transport, and cubic feet lets you compare against other measurements. Example: 10 ft × 12 ft × 6 in yields 60 ft³, 2.22 yd³, and about 2.89 tons. If your site has uneven ground, measure the deepest point and add a small safety margin. The tool updates instantly as you tweak any dimension, so you can experiment with different fill depths before committing.

Pro tips

  • Add 10% extra for compaction and settling
  • Round up to the nearest whole yard to simplify ordering
  • Order a little more than calculated to cover spillage or uneven ground
  • Double‑check depth conversion from inches to feet

Case study

Sam needed to fill a 12 ft × 8 ft area 4 in deep for a patio. The calculator showed 2.96 yd³ and 3.85 tons. He ordered 3 yd³, saved $200 by avoiding an extra yard, and the job finished on schedule.

Frequently asked questions

How do I convert depth in inches to feet?
Divide the inches by 12; the calculator does this automatically.
Why is the weight shown in tons?
Weight helps you estimate delivery cost; we use 1.3 US tons per cubic yard as the standard.
Do I need to round the result?
Round up to the nearest whole yard for ordering; suppliers usually sell by the yard.
What if my site isn’t a perfect rectangle?
Measure the average length and width, or split the area into rectangles and sum the results.
Is the calculator free to use?
Yes, it’s completely free and requires no sign‑up.
