 ```How much does peat (a black, organic kind of dirt) weigh? Please answer in yards per ton. The weight of peat varies signicantly due to how wet or dry it is. Please answer for wet and dry or at least give some kind of a range. I do not need a highly accurate answer -- some good ballpark numbers will do. FYI -- My best guess is that it varies from 1.2 yds/ton to 2.0 yds/ton. Thank you!```
 ```kepes-ga, According to the US Geological Survey report on peat: http://minerals.usgs.gov/minerals/pubs/commodity/peat/510499.pdf the average density of different types of peat varied over a considerable range. Table 6 of the report is titled, aptly, "AVERAGE DENSITY OF DOMESTIC PEAT SOLD IN 1999" and tells us the density (in kg/cu meter) of: sphangnum moss 169-219 hypnum moss 475-578 reed-sedge 557-597 Humus 797-1055 The table also tells us: To convert kilograms per cubic meter to pounds per cubic yard multiply by 1.685. Accordingly, the above table, in pounds per cubic yard is: phangnum moss 285-369 hypnum moss 475-800 reed-sedge 939-1006 Humus 1342-1778 So, the number of cubic yards in a ton (2000 pounds) of peat comes to: phangnum moss 285-369 7.0-5.4 hypnum moss 475-800 4.2-2.5 reed-sedge 939-1006 2.1-2.0 Humus 1342-1778 1.5-1.1 So it seems your guess was awfully good as far as humus is concerned, but other forms of peat, being far less dense, need a lot more cubic yards to make up a ton of the stuff. No doubt, the water content of the peat types is a big factor in the weight difference. I trust this information fully answers your question.
