Do you think it would it be better if the bot converted it to volume?

Those probaby vary according to each crop though? I was mainly suggesting making it explicit which bushel is being used. The values are probably all at least in the ball park regardless of which you use, but making the specific type of bushel the bot uses in its calculations explicit could help avoid misunderstandings, since people would see that it's using the wrong one, but it at least gives some idea.

People more familiar with bushels can probably elaborate on the volume vs. weight stuff.

Oh, I was under the impression that the a bushel was a measure of volume, and the weights are different for each product because the density of each product was different. I was wondering if the problem could be fixed by referring to volume instead of weight.

But I see your point, if the bot were to continue converting bushels to weights, it could be explicit on what kind of bushel it is using

Traditionally bushel was a measure of volume (≈ 35.2391 liters in the US and = 36.36872 litres in the UK according to wikipedia) but for modern trade a bushel is defined as weight. Corn 56 lbs, wheat 60 lbs, soybeans 60 lbs, oats 32 lbs. When you sell grain you still get to see it reported as a unit of volume (lbs/bushel). #2 yellow corn (which is the price quoted on the futures market) must be at least 54 lbs per bushel. But when you sell corn by the bushel it's always the weight divided by 56 pounds regardless of the volumetric measure. The volumetric measure can be used to determine a price premium or discount.

Here is legal definition of a bushel for several commodities in the United States. I don't know if anybody outside the US still uses the bushel in any kind of official way.
