Bulk material calculatorEstimate the cubic yards, cubic feet, bags, and tons of mulch, gravel, topsoil, or sand for a bed or area from length, width, and depth.Deck board calculatorFind the deck boards for a deck: boards = deck area divided by the coverage of one board, plus waste.Drip run time calculatorFind a drip zone's precipitation rate and run time: rate = GPH x 1.604 / area, and run time = target depth divided by the rate.Fence post calculatorFind the posts, sections, and rails for a fence run: sections = length divided by post spacing.Precipitation rate calculatorFind how fast a zone applies water: PR (in/hr) = 96.25 x total gpm / zone area, and the run time to hit a target depth.Paver count calculatorFind how many pavers or bricks an area needs: area divided by the coverage of one unit, plus a waste allowance for cuts and breakage.Runoff calculator (Q=CiA)Estimate peak stormwater runoff from a small site with the rational method: Q = C x i x A, in cubic feet per second.Retaining wall calculatorFind the segmental wall blocks for a wall: face blocks = wall face area divided by the block face area.Slope and grade calculatorTurn rise and run into percent grade, degrees, a run-to-rise ratio, and inches per foot for grading, drainage, and ramps.Sod & seed calculatorFind the sod (square feet and pallets) or grass seed (pounds) to cover an area.
