How these tools are different

Exact geometry and unit conversions are handled in tested calculation libraries. Values that can vary by supplier, product or project—such as bulk density, carton coverage, sod coverage, seed rate, post spacing or waste—stay visible and editable rather than being hidden inside a generic answer.
