Approximate volume
28.57 cu yd
About 0.35 short tons per cubic yard for bark mulch; heavier than fresh chip, lighter than compost. The inverse of the volume-to-weight figure. Light bulky materials fill a container by volume long before they reach its weight limit.
- Conversion factor applied
- 2.86 cu yd per short tons
Converting a bark tonnage into volume is a transport and storage question, since bark is light and bulky enough that vehicle capacity binds long before payload does. The material's practical caution is the same as for any organic mulch: it should sit on the soil surface rather than being dug in, and it must be kept clear of stems and trunks, where trapped moisture against bark causes rot. Depth is a weed-suppression decision rather than an aesthetic one.

This result is a specification — 28.57 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.
