Volume calculations
Multiply length by width by depth, keeping each measurement in the same unit before converting the result.
Field-ready measurement tools
Calculate concrete, gravel, mulch, topsoil, cubic yards, and common measurements with clear units, transparent formulas, and practical estimates.
Quick tool
Division by zero is undefined. Try another divisor.
Start with a project
Estimate how much topsoil you need for beds, lawns, and planting areas.
Open calculatorConvert rectangular dimensions into cubic yards, cubic feet, and cubic meters.
Open calculatorWork out mulch volume and optional bag quantities from area and depth.
Open calculatorEstimate gravel volume, weight, and tons while accounting for material density and waste.
Open calculatorEstimate rectangular slab concrete volume with an optional waste allowance.
Open calculatorUseful by design
Add a clear waste allowance when the ground, cuts, settling, or spillage calls for it.
Enter the measurements you have on site and get common volume conversions immediately.
See the formula, worked example, and assumptions behind every estimate.
Know the numbers
Multiply length by width by depth, keeping each measurement in the same unit before converting the result.
Many bulk materials are sold by the cubic yard. Twenty-seven cubic feet make one cubic yard.
Small depth changes have a large effect on volume. Add extra only when your job conditions justify it.

Common questions
They are planning estimates based on the measurements and assumptions you provide. Confirm product coverage, density, and site conditions with your supplier.
Use a material calculator when you know what you are ordering. Use the cubic yard calculator when you need a neutral volume conversion first.
Yes. Each construction calculator lets you choose inches, feet, yards, centimeters, or meters for relevant dimensions.
