How many cubic yards is 2 tons of pea gravel?

There is a lot of info if you Google pea gravel weight.
The most frequent weight I saw in those postings was about 100 lbs. per cubic ft.
2 tons would be (4000 lbs divided by 100 lbs per cf) 40 cubic feet
Divided by 27 cf (cf in a cy) would be 1.48 cubic uards

My math came out the same, go with Smearcase's numbers.
