How Asphalt Calculator Metric Works
Visual calculation flow
Tonnes = L(m) × W(m) × T(mm÷1000) × Density ÷ 1000 Step 1: Enter dimensions with flexible units (length in m/km, width in m/cm, thickness in mm/cm).
Step 2: All units are normalized to meters internally for consistent calculation.
Step 3: Volume (m³) × Density (kg/m³) = Weight (kg). Bitumen/aggregate breakdown by percentage.
Step 4: Results in kg and tonnes with coverage rate (kg/m²) for material planning.
