Estimate the volume, tons and cost of gravel for a project, with a labor budget. Each dimension has its own unit selector (in/ft/yd/m).
Find each area's volume (length x width x depth, or half that for a wedge, or pi x radius squared for a circle), divide by 27 for cubic yards, then multiply by the material density for tons. Use the unit selector on any field and the material dropdown to set density. The budget planner adds a labor estimate and a line for other project costs.
