    Looking for some help converting square feet of walkway for the amount of stone I need to put under it into tons.

    what, like 21a or 57s?

    length x width x depth= cu. ft.

    cu. ft. / 27= cu. yds.

    cu. yds. x 1.8 tons per cubic yard= tons needed

    If you are doing a large job do not forget to multiply by a compaction/settlement factor. If it is a small job you should be okay with that formula.

    tons per cubic yards is different from material to material.1.8 is high so thats a good bet.

    I thought you multiplied square feet x .08 per inch of material needed and divided by 27 to get number of yards needed?

    same idea, cedar- i.e., for a 6" base you'd multiply times 0.5, etc...

    Now the coolest thing in the world is a ProjectCalc calculator that'll do all the math for you. I keep one on my desk, one in my truck, and one with the laser transit.... just in case.

    call your stone supplier, they usually refer to stone in tons and they have the conversions there

    depends on how they load it.
    if they weigh you then they sell by tons, if they just use a loader they sell per yard.
