Gravel Volume Formula:
Definition: This calculator estimates the volume of gravel needed based on the length, width, and depth of the area to be covered.
Purpose: It helps homeowners and construction professionals determine how much gravel is required for landscaping or construction projects.
The calculator uses the formula:
Where:
Explanation: The calculator converts all measurements to feet, calculates cubic feet, then converts to cubic yards (27 cubic feet = 1 cubic yard).
Details: Accurate gravel estimation ensures proper project planning, avoids material shortages or excess, and helps control project costs.
Tips: Measure the length and width of your area in feet. Enter the desired depth in inches (converted automatically). All values must be > 0.
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 from cubic feet to cubic yards.
Q2: What depth should I use for different projects?
A: Typical depths: 2-4 inches for walkways, 4-6 inches for driveways, 6-12 inches for heavy traffic areas.
Q3: How do I measure irregularly shaped areas?
A: Break into rectangular sections, calculate each separately, then sum the volumes.
Q4: Does this account for compaction?
A: No, consider adding 10-20% more gravel if compaction is expected.
Q5: How many tons is a cubic yard of gravel?
A: Typically 1.2-1.5 tons per cubic yard, depending on material and moisture content.
