Frequently Asked Questions
Q: How do you convert gravel cubic yards to tons?
Multiply the volume in cubic yards by the specific material density in tons per cubic yard (typically 1.4 for crushed limestone). For example: 5 cubic yards × 1.4 tons/yd³ = 7.0 US Tons (14,000 lbs).
Q: How do you convert tons of gravel back into cubic yards?
Divide the total weight in US tons by the aggregate bulk density. For example: 10 tons ÷ 1.4 tons/yd³ = 7.14 cubic yards (approx. 193 cubic feet).
Q: Why does gravel weight vary between dry and wet conditions?
Porous limestone, granite screenings, and gravel piles retain surface moisture after rainfall. Water adds 5% to 10% to measured truck scale weight without increasing dry volume coverage. Quarries measure bulk density in dry loose state according to ASTM C29 standards.
