Weight to Volume For ROLS Building

I though a thread should be started listing what the weight to volume is for amendments we use.This would have been handy while i was figuring out my stuff.
For instance.
EWC 30lbs/ ~5 gallons.
Fish Bone Meal 8 Ounces / cup
Crab Meal 7 Ounces / cup
Kelp Meal 7.5 Ounces / cup
Neem Cake 6.5 Ounces / cup
Alfalfa Meal 2 Ounces / cup
Oyster Flour 8 Ounces / cup
Gypsum 9 Ounces / cup
Soft Rock Phosphate 9 Ounces / cup
Glacial Rock Dust 9 Ounces / cup
Barley Seed 6 Ounces / cup
(Thanks BuildASoil.com)

I like the idea, but we shouldn't forget about the rest of the ENTIRE planet that uses the metric system..
Stupid Americans
(yes i'm American, but we are stupid in a LOT of ways)

I agree. I wish we (United States) had converted to the metric system back when it was starting to be taught to my parents.
But im not going to do the metric. Im lazy. lol

Have a new one to add.
Wakefield Biochar weights 22 lbs for 1 cubic foot/7.48 gallons.

Yeah I just started a new soil replacing perlite and coco. I did 25% mvp and 13% biochar. Letting it sit I'll keep you updated.
