# Real Gravel Calculator (https://realgravelcalculator.com)
> The authoritative, US-first gravel estimating platform and precision aggregate calculator for homeowners, contractors, landscapers, and civil engineering projects.

## Core Summary
Real Gravel Calculator calculates volume (cubic feet, cubic yards, cubic meters), weight (US tons, pounds, metric tonnes), retail bags (0.5 cu ft, 1.0 cu ft), estimated material cost, compaction/waste factors, and truckload logistics for any gravel or aggregate project.

## Key Features & Calculators
- Primary Gravel Calculator: https://realgravelcalculator.com/gravel-calculator
  - Supports 6 geometric shapes: Rectangle, Circle, Triangle, Trapezoid, L-Shape, and Custom Area.
  - Multi-area summation for complex projects (e.g. main driveway + turnaround + parking apron).
  - Reverse calculation modes: calculate required coverage from known tonnage, or calculate depth from known gravel quantity.
- Driveway Two-Layer Gravel Calculator: https://realgravelcalculator.com/driveway-gravel-calculator
  - Calculates subbase (e.g. Crusher Run 4-6") and wearing surface (e.g. #57 Stone 2-3") independently.

## Core Conversion Formulas
- Area (Rectangle) = Length (ft) × Width (ft)
- Depth in Feet = Depth in Inches ÷ 12
- Volume in Cubic Feet = Area (sq ft) × Depth (ft)
- Volume in Cubic Yards = Volume (cu ft) ÷ 27
- Volume with Waste/Compaction = Base Cubic Yards × (1 + Waste% / 100) [Typical: 10% for loose gravel, 15-20% for compacted crusher run]
- Weight (US Tons) = Cubic Yards × Material Density (tons/yd³)
- Total Pounds = US Tons × 2,000 lbs
- Number of 0.5 cu ft Bags = Volume in Cubic Feet ÷ 0.5
