Gravel Volume Formula:
Definition: This calculator estimates the volume of gravel needed based on the area to be covered and the desired depth.
Purpose: It helps homeowners and construction professionals determine how much gravel is required for landscaping, driveways, or other projects.
The calculator uses the formula:
Where:
Explanation: The area multiplied by depth gives cubic feet, which is then converted to cubic yards by dividing by 27.
Details: Accurate gravel volume estimation ensures proper coverage, prevents material shortages or excess, and helps with budget planning.
Tips: Enter the area in square feet and depth in inches. The calculator automatically converts depth to feet for 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 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 drainage areas.
Q3: How do I measure the area?
A: For rectangular areas: length × width. For irregular shapes, break into rectangles or use an online area calculator.
Q4: Should I account for compaction?
A: Yes, consider adding 10-20% more gravel if heavy compaction is expected.
Q5: How many square feet does 1 cubic yard cover?
A: At 3 inches depth: 1 cu yd covers ~108 sq ft. At 6 inches: ~54 sq ft.
