How this was calculated
Formula source(s)
- Typical bulk density used here: approximately 0.4 short tons per cubic yard
- Bulk density varies with moisture, compaction and grading — the supplier's weighbridge ticket governs
Inputs used
- Mulch volume (yd³)
- 10
Intermediate steps
- Conversion factor applied
- 0.4 short tons per yd³
Confidence note: About 0.4 short tons per cubic yard for typical wood mulch; density varies widely with material and moisture. This is a planning figure, not a specification. Confirm the density with your supplier before ordering by weight.
What this calculation does not cover
- The volume is fixed; the weight is not. Mulch takes up rain, so the same cubic yards weigh considerably more after a wet spell than they did dry, and a haulier, a skip firm or a weighbridge charges on what the load weighs on the day rather than on the figure worked out when the job was priced.
- An old layer being stripped out is not this material. It comes up matted and part-rotted, with soil and leaf litter in it, and weighs appreciably more per cubic yard: a disposal tonnage taken from the bed's in-place volume comes out low.
- The tonnage is only as good as the volume it was worked from. Where a yard loads by the bucket rather than filling a calibrated bin or a bulk bag of stated volume, the cubic yards going in are an estimate, and this conversion carries that error straight through to the weight.

Mulch is the lightest bulk material most sites handle, at roughly a third the weight of soil per cubic yard, which is why it is nearly always sold by volume rather than weight. The conversion is still occasionally needed — for haulage planning, or where a supplier prices by the ton — and the density assumption here should be treated loosely, because bark, wood chip and composted mulches differ from one another far more than aggregates do. Where weight actually matters, such as a trailer's payload or a roof-garden loading, get the figure from the supplier rather than from a generic average.
