Food Storage Planner

Why we give you a range instead of a number

Because nobody can honestly give you the number. Extension services publish shelf life and packing method; none of them publish a fill-weight table, and the figures circulating on storage sites disagree badly. Wheat gets quoted anywhere from 25 to 37 pounds a bucket. Oats run from 15 to 35, because half the tables never noticed that rolled oats and whole groats are different foods with different densities. One widely copied chart has its pound and kilogram columns mismatched.

So a calculator that hands you 36.2 poundsis not being precise, it is being confident about somebody else's guess. The range above is honest about the spread, and the method below closes it properly.

Weigh one quart. That is the whole trick.

A 5-gallon bucket is exactly 20 quarts. Fill a quart jar with the grain you actually bought, set it on a kitchen scale, subtract the jar, and multiply by twenty. That is your bucket capacity, for your grain, at your moisture content and packing. It takes half a minute and it beats every table on the internet, this one included.

Do it once per food, write it on the lid, and you never have to trust a chart again.

The bagging penalty nobody plans for

Here is the mistake this tool exists to catch. People price out buckets using loose capacity, roughly a third of a hundredweight per pail, then decide to bag everything in 1-gallon mylar for rotation, and come up short on pails.

Only about four 1-gallon bags fit a 5-gallon bucket, not five. Bags do not tessellate; they slump, they trap air between them, and the fifth one will not go in without a fight you will lose. So the same weight of rice needs meaningfully more buckets once it is bagged. Decide your packing method first, then count pails. If you would rather not pay that tax, one 5-gallon bag per bucket wastes nothing, at the cost of committing to open thirty-odd pounds at a time.

Does the bucket have to be food-grade?

Only if the food touches it. Sealed mylar is the actual food contact surface and the actual oxygen barrier, so when every pound is bagged first the pail is doing a purely mechanical job: keeping rodents out and weight off the bags. If you are pouring grain straight into the plastic, then yes, buy food-grade. We work through that trade in bucket vs mylar bag.

What about the absorbers?

The totals above follow the same sizing as our oxygen absorber calculator: roughly 300cc per gallon of dense grain, 500cc per gallon of airy food like beans and pasta, and about 2,000cc for a bucket-sized bag. Round up without worrying. And keep the dry-food rule in front of you, because an oxygen-free container is the wrong place for anything moist.
