What Is a Tonnage Calculator?
Estimate gravel, asphalt, sand, stone, and dirt weight for any construction project
A tonnage calculator converts your project dimensions — length, width, and depth — into material weight in tons. Whether you're planning a gravel driveway, an asphalt parking lot, a sand base for pavers, or a stone pathway, knowing the tonnage ensures you order exactly the right amount of material.
30+ Materials
Gravel, asphalt, sand, stone, soil & more
4 Area Shapes
Rectangle, circle, triangle & known area
Dual Units
Imperial (ft/in/lbs) & metric (m/cm/kg)
Truck Loads
Estimated deliveries at ~20 tons each
Compaction
Adjust for loose vs compacted material
Cost Estimate
Per-ton pricing with multi-currency
Waste Factor
5–10% overage for real-world accuracy
Coverage Table

Contractors, landscapers, and DIY homeowners use tonnage calculators to avoid the two costliest mistakes in material ordering: over-ordering (wasted money and leftover piles) and under-ordering (project delays and extra delivery charges). This calculator supports 30+ materials, four area shapes, and both imperial and metric units with adjustable density and compaction settings.
How to Calculate Material Tonnage
A four-step guide to converting area and depth into tons
Choose Area Shape
Select rectangle, circle, triangle, or enter a known area. For irregular spaces, break them into sections and calculate each separately.
Enter Dimensions
Input length, width, diameter, or base/height depending on your shape. Add the material depth — common depths are 2–4 inches for gravel and 3–6 inches for asphalt.
Select Material
Choose from 30+ materials across gravel, sand, asphalt, soil, and specialty categories. Each material has a standard density measured in lbs/ft³ or kg/m³.
Review Results
Get total tonnage, volume in cubic yards, weight, truck loads, and cost estimate. Check the coverage reference to understand how far 1 ton spreads at different depths.
Core Formula
Tonnage = (Area × Depth) × Density ÷ 2,000
Area is calculated by shape: Rectangle = L×W, Circle = π×(D÷2)², Triangle = ½×B×H. Depth must be in feet (divide inches by 12). Density is in lbs/ft³. Divide by 2,000 to convert pounds to short tons, or by 2,204.62 for metric tonnes.

Tips for Ordering Material
Practical advice to save money and avoid delivery headaches
Add 5–10% Waste Factor
Always order extra. Spillage, uneven ground, and compaction reduce effective coverage. For irregular shapes, use 10–15% waste.
Know Your Tons: Short vs Metric
US short ton = 2,000 lbs. Metric tonne = 2,204 lbs. Confirm which unit your supplier uses — a 10% difference can mean an extra delivery.
Measure Twice, Order Once
Break complex areas into rectangles, circles, and triangles. Calculate each section and sum the results. Round up, not down.
Account for Compaction
Compacted gravel weighs ~15% more than loose. If your material will be mechanically compacted, enable the compaction toggle.
Common Mistakes When Calculating Tonnage
Avoid these frequent errors that lead to wrong orders
Forgetting the Waste Factor
Ordering exact calculated tonnage almost always results in a shortfall. Second delivery fees often exceed the cost of 5% extra material.
Confusing Cubic Yards with Tons
Yards measure volume; tons measure weight. Different materials have different densities — 1 yd³ of gravel ≠ 1 ton. Always convert using the correct density.
Ignoring Moisture Content
Wet sand can weigh 20% more than dry sand. If ordering after heavy rain or for underwater use, factor in moisture weight.
Using Inches for Depth in Formulas
All depth values must be in feet for the formula Volume = Area × Depth. Divide inches by 12. Our calculator handles this automatically.
