How to Use the Asphalt Tonnage Calculator
This calculator estimates the tons of asphalt needed for a rectangular area. All inputs are in imperial units (feet, inches, lb/ft³).
- Enter Length (ft) – The length of the area in feet.
- Enter Width (ft) – The width of the area in feet.
- Enter Thickness (in) – The desired asphalt thickness in inches.
- Enter Density (lb/ft³) – The asphalt density (default 145 lb/ft³ is typical).
- Click Calculate.
Result: The required asphalt in tons appears below, along with a step-by-step breakdown of the calculation.
Formula: (Length × Width × Thickness/12) × Density ÷ 2000

Frequently Asked Questions
It calculates the volume of asphalt needed (length × width × thickness) and multiplies by the density (typically 145 lb/ft³) to get weight in pounds, then converts to tons (2000 lb per ton).
Typical asphalt density is around 145 lb/ft³ (2.3 g/cm³), but it can vary. You can adjust the density input for different mixes.
This calculator assumes a rectangular area. For irregular shapes, divide into rectangles and sum the results.
