FAQs
Use Gravel Weight when you know project dimensions or volume and need tonnes, bags, delivery loads, or cost. Use Gravel Coverage when you know any two of quantity, area, and depth and need the missing value.
Gravel Weight starts from a measured project shape or direct volume and calculates the order quantity. Gravel Coverage works in reverse or bidirectionally, finding coverage area, quantity needed, or achievable depth.
