I think some where on here there's a post with a conversion chart for weight to cubic feet I will try to find it and post it i think it said 1 cubic foot of coal = 50 to 59 lbs. ill look for it

94# if it a solid square foot block, 69# when broken.
I believe it continues to get lighter as you make it smaller sizes.

From an old book (1980) in my library.

Taking into account the slight variations of coal qualities among producers the following table list average weights.

Coal Size - Lbs/Cu Ft
Broken ------- 56.85
Egg ----------- 57.74
Stove --------- 58.15
Nut ------------ 58.26
Pea ----------- 53.18
Buckwheat -- 54.04

The table does not have any other sizes. On another page in the book I found a dimensional chart for each size of coal. I did some mathematical analysis and plotting of the data to see if I could derive the figures for Rice and Barley and came up with some strange numbers. It's possible that there is/are other variable(s) in there such as accuracy of the data gathered (although they do show the Lbs/Cu Ft to two decimal places) and/or the operating characteristics of the breaker.
My best guess for Rice and Barley would be in the 53 to 54 area.

The rice would be slightly less per cubic ft. than the Buck and the Barley would be even less.
