Gravel Volume Formula:
Definition: This calculator estimates the volume of gravel needed based on the project area dimensions (length, width, and depth).
Purpose: It helps construction professionals and DIYers determine how much gravel is required for projects like driveways, walkways, or foundations.
The calculator uses the formula:
Where:
Explanation: The calculator multiplies the three dimensions to get cubic feet, then divides by 27 to convert to cubic yards.
Details: Accurate volume calculation ensures proper material ordering, cost estimation, and project planning.
Tips: Enter the length and width in feet, and depth in inches. The calculator automatically converts depth to feet in the calculation.
Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard, so we divide by 27 to convert the volume from cubic feet to cubic yards.
Q2: What's a typical gravel depth for different projects?
A: Driveways typically need 4-6 inches, walkways 2-3 inches, and foundations 6-12 inches depending on soil conditions.
Q3: How do I measure irregular areas?
A: Break the area into rectangular sections, calculate each separately, then sum the volumes.
Q4: Does this include compaction factor?
A: No, consider adding 10-20% to the calculated volume to account for compaction.
Q5: How many tons is a cubic yard of gravel?
A: Typically 1.2-1.5 tons per cubic yard, depending on material density.
