Meaning, I thought 100 pounds of rice would take up slightly less space than a 100 pounds of stove size. I've never tried a comparison.

Well, I also always thought that rice coal would take up less volume per ton than stove coal, just not as much less as Isayre was saying, because I was questioning his calculation because of the estimate of the size of the pail he was using, knowing that pails can vary. I wasn't questioning his method. Since the pail he was using actually was actually bigger than he originally estimated, then using that new data in his formula (

bold print are the changes):

If you assume that a filled to the brim 5 gallon pail is actually holding about 5.57 gallons to the brim, then:

41 / 5.57 = 7.36 lbs/gallon

7.4805 gallons per cubic foot x 7.36 lbs./gallon = 55.05 lbs. per cubic foot

4 tons = 8,000 lbs.

8,000 /55.05 = 145 cubic feet

I am not sure what margin of error Larry would want to apply to that as he did previously. The result above is the same as his calculation plus his ballpark error margin. If you used the same 6 cu ft margin of error then he would estimate the 4 tons of pea to be 151 cubic feet.

I found in my notes from setting up my coal bin seven years ago, a volume figure of 38 cubic feet per ton for pea coal and that is the figure I used for my bin calculations. I am not sure where that figure came from but using that figure for an estimate yields a volume of 152 cubic feet for four tons of pea coal.

Larry and I are not far off.

I have some pea and some buckwheat, a "five gallon pail" that I will measure, and a scale. I will go through the exercise also and we will get to the bottom of the matter.
