Civil Engineering & Bulk Aggregate Tonnage Standards
Earthwork construction projects specify bulk aggregate materials in cubic yards or tons.
Primary Tonnage Formulas
- Net Volume in Cubic Yards: V_net = Length (ft) × Width (ft) × (Depth (in) / 12)27
- Gross Volume with Compaction: V_gross = V_net ×
- US Short Tons (2,000 lbs): Short Tons = V_gross × Density
- Metric Tonnes (1,000 kg): Metric Tonnes = Short Tons × 0.907185
- Tri-Axle Dump Truck Loads: Loads = Short Tons16
Standard Bulk Material Densities
- Crushed Stone / Road Base: 1.40 tons / cu yd ≈ 2,800 lbs/cu yd
- Dry Sand: 1.30 tons / cu yd ≈ 2,600 lbs/cu yd
- Wet Packed Sand: 1.50 tons / cu yd ≈ 3,000 lbs/cu yd
- Screened Topsoil: 1.10 tons / cu yd ≈ 2,200 lbs/cu yd
- Hot Mix Asphalt: 1.35 tons / cu yd ≈ 110 lbs / sq yd / inch
- Ready-Mix Concrete: 2.02 tons / cu yd ≈ 4,050 lbs/cu yd
How to Use This Calculator
Enter your Project Length (Feet) (e.g. 50 in ft), Project Width (Feet) (e.g. 10 in ft), Depth / Thickness (Inches) (e.g. 4 in in), Bulk Material & Density — choose from Crushed Stone / Base Gravel (1.40 tons / cu yd), Dry Sand (1.30 tons / cu yd), Wet Sand (1.50 tons / cu yd), Compaction & Waste Margin (%) (e.g. 10 in %), and Material Price Per US Ton (/ton) (e.g. 38.50 in /ton).

Understanding Your Result
Date and time results depend on the reference timezone — all calculations here use the local system clock. For legal or contractual purposes, "days between" dates should be clarified as calendar days (counting the end date) vs. business days (excluding weekends and public holidays). Age calculations use full completed years — someone born on December 31 is the same age as someone born on January 1 of the same year for most legal purposes until their actual birthday.
💡 Mathematical Rigor & Applied Context
- This calculator applies exact mathematical definitions following conventions established by NIST and international standards bodies.
- Rounding errors accumulate across multi-step calculations. For precision-critical work, maintain extra significant figures through all intermediate steps.
- Many mathematical concepts have multiple valid formulations — if a result seems unexpected, verify which convention or definition applies to your context.
- Dimensional analysis (unit tracking) is the fastest way to catch formula errors. Every term in an equation must have consistent, compatible units.
- Numerical methods used in digital calculators introduce floating-point precision limits (~15 significant digits for IEEE 754 double precision).
- For statistical and probabilistic calculations, always specify whether you are working with population parameters or sample statistics — formulas differ.
- Visualizing a problem geometrically or testing with known boundary values (zero, infinity, negative) reveals hidden errors faster than algebraic checking.
- When in doubt, validate your result against a simplified hand calculation or a published worked example from a textbook or standards document.
