How do you convert pea gravel from weight to cubic meters? - Answers

First, you need the density of pea gravel. This depends heavily on particle size and cleanness of the gravel, but a density of 3000lb/yard3 is a realistic estimate. If you want the final answer in metric, it's useful to convert the density to 1780kg/meter3. Knowing this density, you can use it as a conversion factor. You just take the mass of your Pea gravel (for example 50kg) and multiply it by 1 meter3/1780kg to make the units cancel out. Or if you want it easy, just take the weight of your pea gravel in kilograms and divide it by 1780 to get volume in cubic meters. This is a very rough estimate, and actual values depend on the density of the pea gravel being used. The basic idea for any conversion is that you get the density and make sure it uses cubic meters.
