Product Calculation Instructions

*NOTES

All of the product weights and conversions are approximations only. There is no warranty, expressed or implied, that our products equal those weights or conversions. There can be wide variances in the weight of various products due to a number of factors, including the moisture content, season, recent weather (dry vs. wet), the material density, the composition of the product, the absorptive qualities of the product, changes in the pit, change in supplier, etc. As a general rule, denser material without much void space is heavier, such as rockery rock or pit run gravel. By the same token, bigger rocks and boulders are denser and thus heavier than smaller loose products, such as sand, which are lighter. The greater the capacity for a product to absorb water (particularly weather-sensitive materials such as topsoil, cinders, clay, etc.) the more prone that material is to changes in weight due to moisture, rain, or other wet conditions. By the same token, well-drained materials such as pea gravel, 7/8", or 1-2" drain gravel are not very susceptible to weight changes due to the presence of moisture. A crushed gravel product with a higher content of fines (or sandy binder) such as State Spec. 5/8" or 1-1/4" crushed gravel (typically 50% fines) is typically heavier than a clear crushed product such as 5/8" or 1-1/4" Clear (typically 5-10% fines), due to there being more void space in the Clear crushed products.
