One engine behind all of them
Every calculator on this list runs dedicated calculation code. That is not an implementation detail, it is the point: it means two pages about the same material cannot give you two different answers for the same job, which is a failure mode that is surprisingly common on calculator sites and impossible to spot from the outside.
Which one to use
If you are covering an area at a depth, start with the gravel calculators on the home page. Use the construction calculators for concrete, paint, pavers and stairs. Use the landscaping calculators for mulch, topsoil and sod. Use the lumber calculators for board feet and deck materials. Each page explains what it covers and links to related tools.
