How the Crushed Limestone Calculator (#57, #411 & Screenings) Works

High-calcium angular white-to-gray limestone aggregate offering bright aesthetics and superior mechanical interlock for driveways and pads. Our Crushed Limestone Calculator (#57, #411 & Screenings) computes exact geometric volume in cubic feet and cubic yards, then converts volume into US short tons (2,000 lbs) using the typical bulk density of Crushed Limestone (#57 / #411 / Screenings) (2,780 lb/yd³ or 1.39 tons/yd³).

Mathematical Formula for Crushed Limestone:
1. Area (sq ft) = Length (ft) × Width (ft)
2. Volume (cu ft) = Area (sq ft) × [Depth (inches) ÷ 12]
3. Volume (cu yd) = Volume (cu ft) ÷ 27
4. Recommended Volume = Base Volume × (1 + 10% Ordering Adjustment)
5. Estimated Tons = Recommended Cubic Yards × 1.39 tons/yd³

Step-by-Step Worked Example

Example Project: 50 ft × 12 ft Area at 4 Inches Depth (+10% Adjustment)

Surface Area: 50 ft × 12 ft = 600 sq ft.
Base Volume: 600 sq ft × (4 ÷ 12) = 200.0 cu ft (7.41 cubic yards).
With +10% Ordering Adjustment: 7.41 yd³ × 1.10 = 8.15 cubic yards.
Weight in US Short Tons: 8.15 yd³ × 1.39 tons/yd³ = 11.33 tons (22,652 lbs).

Frequently Asked Questions

Multiply your project length (50 ft) by width (12 ft) to get area (600 sq ft). Multiply by depth in feet (4 in ÷ 12 = 0.33 ft) to get 200.0 cubic feet, then divide by 27 to get 7.41 base cubic yards. Adding a 10% ordering adjustment gives 8.15 yd³, which equals 11.33 US short tons at 2780 lb/yd³.

One cubic yard (27 cubic feet) of Crushed Limestone (#57 / #411 / Screenings) weighs approximately 2,780 pounds, or 1.39 US short tons (103 lbs per cubic foot). Typical regional quarry densities range between 2,650 and 2,950 lb/yd³.

For most crushed limestone installations, a typical compacted depth is 4 inches (our default preset uses 4 inches). Always excavate soft organic topsoil and install woven or non-woven geotextile fabric before spreading aggregate.

At 1.39 tons per cubic yard, 1 US short ton equals 0.72 cubic yards (19.4 cu ft). That covers approximately 117 sq ft at 2" deep, 78 sq ft at 3" deep, and 58 sq ft at 4" deep.
