Definition: This calculator estimates the weight of river rock in tons based on its volume in cubic yards and density.
Purpose: It assists contractors, landscapers, and homeowners in determining the weight of river rock needed for projects like garden beds, pathways, or driveways, aiding in material ordering and transportation planning.
The calculator uses the following formula:
Where:
Explanation: The volume in cubic yards is multiplied by the density in tons per cubic yard to calculate the weight in tons.
Details: Accurate weight calculation ensures proper material estimation, supports transportation planning, and helps maintain structural integrity for landscaping or construction projects.
Tips: Enter the volume (must be > 0) and density (must be > 0, default is 1.3 tons/cu yd). The calculator computes the weight in tons, rounded to 3 decimal places.
Q1: Why is the result in tons?
A: Tons are a standard unit for measuring the weight of materials like river rock, especially for ordering and transportation.
Q2: How do I find the volume in cubic yards?
A: Use a volume calculator (e.g., Area (sq ft) × Depth (ft) ÷ 27) or measure the volume of river rock needed for your project.
Q3: How do I determine the density?
A: Check with your material supplier. Typical density for river rock is around 1.3 tons/cu yd, but it may vary (1.2–1.4 tons/cu yd).
Q4: Can I use this for other materials?
A: Yes, if you know the density of the material in tons per cubic yard, the calculator can estimate its weight.
Q5: Does this include waste or compaction?
A: No, this is a base calculation. Add 10–20% extra volume to account for waste or compaction before calculating weight.
