How to use it
- Enter length in feet
- Enter width in feet
- Enter depth in inches
- Click calculate to see cubic feet, cubic yards, and tons
The calculator turns the length, width and depth you enter into three useful measures: total cubic feet of topsoil, how many cubic yards that volume equals, and an approximate weight in US tons. Knowing the cubic yards tells you how many bulk bags or truckloads to order, while the ton estimate helps you compare cost against material specifications. The tool assumes 1 cubic yard of topsoil weighs about 1.3 US tons, a standard industry figure. Simply input dimensions, hit calculate, and read the three results. Use the cubic‑foot number for small projects, the yard figure for larger landscaping jobs, and the ton estimate when contractors quote based on weight. The conversion uses the exact relationship that 27 cubic feet equal one cubic yard, and then multiplies by the 1.3‑ton factor. This ensures the weight figure aligns with most supplier tables, so you can order the right amount without costly over‑ or under‑delivery.
Pro tips
- Add 5‑10% extra volume for settling and compaction
- Round up to the nearest whole cubic yard when ordering bulk
- Check supplier weight tables; most use 1.3 tons per cubic yard
- Double‑check depth conversion from inches to feet
Real-life examples
- Planning a new flower bed and need to know how much topsoil to buy
- Estimating material for a backyard lawn renovation
- Getting a contractor quote based on weight rather than volume
Case study
Sam needed to fill a 12 ft × 8 ft garden bed 4 in deep. The calculator showed 2.67 cubic yards, about 3.5 tons. He ordered exactly that amount, avoiding a $150 over‑order and finishing the project on schedule.
