How to use it
- Enter length in feet.
- Enter width in feet.
- Enter depth in inches.
- Read cubic yards, cubic feet, and ton estimate.
What it does – The calculator converts your rectangular area (length × width × depth) into cubic feet, then into cubic yards (1 yd³ = 27 ft³) and finally into an approximate tonnage using the industry standard 1.4 US tons per cubic yard.
Why it matters – Knowing cubic yards tells you how many dump‑truck loads to order; the ton estimate helps you compare product specifications and budget.
How to read the results – Cubic feet is the raw volume, cubic yards is the common purchase unit, and tons is the weight you’ll pay for. All numbers are rounded to two decimals for easy ordering.
Example – A 10 ft × 10 ft area 6 in deep yields 50 ft³, 1.85 yd³, and about 2.59 tons.
Pro tips
- Add 5‑10% extra for compaction.
- Round up to the nearest half‑yard for truck loads.
- Double‑check depth conversion from inches to feet.
- Order a little more than the calculator shows to avoid shortfalls.
Real-life examples
- A homeowner planning a new driveway needs to know how many tons of gravel to order.
- A landscaper estimating material for a garden path wants quick volume and weight.
- A contractor budgeting for a parking lot base checks the tonnage to price the job.
Case study
Mike needed a 12 ft × 8 ft patio 4 in deep. The calculator showed 2.96 yd³ and 4.14 tons. He ordered 5 tons, saved a delivery trip, and finished on budget.
