CalculatorMulchConversion and cost calculators
Three conversions sit under every order on this site — cubic feet to yards, yards to bags, and yards to tons.
Bag coverage chart
Coverage is not a property of the bag. It is a property of the depth.
Bulk vs bagged calculator
Bulk is cheaper per yard and not always cheaper per job.
Cubic metres to cubic yards
Half the world buys soil by the tonne and reads advice written in yards.
Bags to cubic yards converter
The one number that makes a shelf price and a bulk quote comparable.
Cubic yards calculator
One formula sits under every material on this site, and it hinges on a single number.
Cubic yards to tons calculator
The same volume can be a light load or an illegal one. Density decides which.
Almost every argument at a supply yard is a unit problem rather than a price problem. The bed is in square feet, the order is in cubic yards, the shelf is in bags and the ticket is in tons — and the only way to know whether two quotes are for the same thing is to put them all in the same unit first. The tools here do exactly that, and nothing else: volume from measurements, bags either way, and weight by material.
Frequently asked questions
Why 27?
Because a cubic yard is a cube three feet on every side, and 3 × 3 × 3 is 27 cubic feet. Every other conversion on this site is built on it: bags per cubic yard is 27 ÷ bag size, and coverage per cubic yard is 27 ÷ depth in feet.
Is there one conversion from cubic yards to tons?
No, and that is the point of having a calculator for it. A cubic yard of mulch weighs about 700 lb and a cubic yard of river rock about 2,800 — four times as much for exactly the same volume. Any single ‘yards to tons’ number you find online is only true for one material.
Which of these do I actually need?
If you have measurements, start with the cubic yards calculator. If you already know the yardage and want a shopping list, use the bags converter. If you know the yardage and need to know whether your vehicle can carry it, use the tons calculator — that is the one that stops a Saturday going wrong.
