    Is there a different formula for figuring how much gravel you need then the one you use for mulch?

    I plan on using some brown river rock in several beds and sloping areas. Client is strongly against mulch.

    anyone? I have a good idea of how much I need but was wondering if the formula was different since gravel is sold in tons and not yards. At least that's what I've seen at a few different places.

    Thanks man. Yeah I've seen a few of these "calculators" but was wondering how you calculate. You know, mulch is: sq ft X depth divided by 27. Just wondering, not a huge deal I guess since there is always an online calculator.

    with stone around here the figure it by the ton and my expirence is that a "yard" of stone weighs about 1.5- 1.75 tons.

    #3 River gravel is very close to 1 ton per yard.

    I've always had a hard time estimating river gravel. I estimated 8 yards for a job once and only used 4.5. Fine by me, I saved 70 bucks.

    you can buy rock by the ton. They will tell you how much area it will cover. 1 ton of 1-2" river rock covers about 90sqft. So what you need to do is measure where its going... say 10'x4' = 40sqft divide by 90 is .44. So about 1/2 ton.
