Gravel Weight Formula:
From: | To: |
Definition: This calculator estimates the weight of gravel needed based on area, depth, and material density, specifically designed for local gravel yard calculations.
Purpose: It helps homeowners and contractors determine how much gravel to purchase from local suppliers for landscaping and construction projects.
The calculator uses the formula:
Where:
Explanation: The formula calculates volume in cubic feet, converts to weight in pounds using density, then converts to tons by dividing by 2000.
Details: Proper calculations ensure you purchase the right amount from local gravel yards, avoiding costly overages or project delays from shortages.
Tips: Measure your area accurately in square feet, determine desired depth (convert inches to feet if needed), and use standard density (120 lb/ft³) unless your supplier specifies otherwise.
Q1: How do I measure the area for gravel?
A: For rectangular areas, multiply length × width. For circular areas, use π × radius². Break complex areas into simple shapes.
Q2: What depth should I use for different projects?
A: Typically 4-6 inches (0.33-0.5 ft) for driveways, 2-3 inches (0.17-0.25 ft) for walkways, and 1-2 inches (0.08-0.17 ft) for decorative purposes.
Q3: Why does gravel density vary?
A: Density depends on material type (crushed stone vs. pea gravel), size, and moisture content. Always check with your local gravel yard.
Q4: How many tons are in a cubic yard of gravel?
A: Approximately 1.4 tons per cubic yard (varies by density). Our calculator converts directly to tons for easier purchasing.
Q5: Should I add extra for compaction?
A: Yes, consider adding 10-15% to your total if the gravel will be compacted, or ask your local yard for their recommendation.
