Construction & Landscaping Calculators
Eliminate project guesswork. Calculate exact cubic yards, US tons, premix bags, and square footage for concrete, gravel, mulch, and flooring with zero server uploads.
Mulch & Topsoil Calculator
Calculate cubic yards, 2 cu ft & 3 cu ft bags, bulk delivery vs bagged pricing, and compaction allowances for garden beds and borders.
Gravel & Crushed Stone Calculator
Calculate US tons, cubic yards, and 50-lb bags for driveways, French drains, and paths. Includes density factors for pea gravel, river rock, and limestone.
Concrete Pour & Pre-Mix Bag Calculator
Calculate cubic yards and bags (80 lb, 60 lb, 50 lb) for slabs, post footings, circular Sonotubes, and steps with ready-mix truck cost comparisons.
Square Footage & Flooring Area Calculator
Measure square footage for single rooms, multi-room floorplans, L-shaped zones, and circles. Includes tile box coverage, cutting waste buffers, and paint estimates.
Standard Bulk Material Density & Bag Volume Constants
1 Cubic Yard = 27 Cubic Feet
13.5 Bags @ 2.0 cu ft per bag
9.0 Bags @ 3.0 cu ft per bag
1 Cubic Yard ≈ 1.35 to 1.40 US Tons
1 US Ton = 2,000 lbs (40 bags @ 50 lbs)
1 Ton covers ~100 sq ft @ 2" depth
1 Cubic Yard = 27 cu ft (4,000 lbs)
45 Bags @ 80 lbs (0.60 cu ft/bag)
60 Bags @ 60 lbs (0.45 cu ft/bag)
