Gravel Calculator Material Estimator
Estimate gravel volume, weight, and material cost from area, depth, density, waste, and price per tonne.
FormulaVolume = length x width x depth; tonnes = volume x density / 1000
Formula
Gravel quantity
Volume = length x width x depth; tonnes = volume x density / 1000
A 5 m by 4 m area at 10 cm depth needs about 2 cubic meters before waste.
