Gravel Tonnage Formula:
From: | To: |
Definition: This calculator estimates the weight of gravel in tons based on volume and material density.
Purpose: It helps determine how many tons of gravel are needed for construction projects, landscaping, or drainage applications.
The calculator uses the formula:
Where:
Explanation: The volume is multiplied by density to get pounds, then divided by 2000 to convert to tons.
Details: Accurate tonnage calculations ensure proper material ordering, cost estimation, and project planning.
Tips: Enter the gravel volume in cubic feet and density (default 110 lb/ft³). Typical gravel density ranges from 100-120 lb/ft³.
Q1: How do I measure gravel volume?
A: Calculate volume as length × width × depth (all in feet) for rectangular areas, or use specialized formulas for other shapes.
Q2: Why 2000 in the formula?
A: There are 2000 pounds in 1 ton, which converts the weight from pounds to tons.
Q3: What affects gravel density?
A: Density varies by material type (crushed stone vs. pea gravel), moisture content, and compaction.
Q4: Should I round up the calculated tons?
A: Yes, it's recommended to round up to the nearest 0.25 or 0.5 ton to ensure you have enough material.
Q5: How accurate is this calculation?
A: It provides a good estimate but actual needs may vary by 5-10% due to compaction and material variations.
