Could anyone tell me how much rabbit pellets weigh? If I feed .25 cup per day for 4 months that is 120 cups or 7.5 gallons. This online calc has a converter for cups into pounds. Is cup a measurement of weight as well as volume ? http://www.calcul.com/measurement?from=120&fromUnit=d-4&toUnit=d-5

All brands of rabbit pellets are going to weigh different. You pretty much have to have a scale to figure out how much to feed.

No, a cup is not a measure of weight as well as of volume. Think about it. Is a cup of feathers going to weigh the same as a cup of lead? You need a scale. Inexpensive ones are readily available and very handy to have around.

never weighed pellets. But I'd be willing to bet, if you figured about 60 pounds to a bushel, and a bushel is about 8 gallons, you will be in the general ballpark.
