Understand the mathematical formulas behind our asphalt calculator and learn how to calculate asphalt volume, weight, and cost manually.
Let our calculator do the work for you with instant, accurate results.
Use CalculatorFormulas for measurements in millimeters, cubic meters, and metric tons
Where: Length, Width, and Depth are in millimeters (mm)
Example:
Driveway: 10,000mm × 5,000mm × 75mm
Volume = (10,000 × 5,000 × 75) ÷ 1,000,000 = 3.75 m³
Common Densities: Standard Hot Mix = 2.36 t/m³, Warm Mix = 2.35 t/m³
Example:
Volume: 3.75 m³, Standard Hot Mix (2.36 t/m³)
Weight = 3.75 × 2.36 = 8.85 tonnes
Formulas for measurements in inches, cubic yards, and US tons
Where: Length, Width, and Depth are in inches. 46,656 = 12³ (cubic inches per cubic yard)
Example:
Driveway: 394" × 197" × 3"
Volume = (394 × 197 × 3) ÷ 46,656 = 4.97 yd³
Note: 1.685 is the conversion factor from metric density to US tons per cubic yard
Example:
Volume: 4.97 yd³, Standard Hot Mix (2.36 t/m³)
Weight = 4.97 × 2.36 × 1.685 = 19.75 US tons
How to estimate the total cost of your asphalt project
Cost Factors to Consider:
Always add 5-10% extra material to account for:
Professional Tip: These formulas provide estimates. Always consult with local contractors and suppliers for the most accurate pricing and material requirements for your specific project.
