Compacted?

Depends on what kind of sand, it’s basically just chaos with tiny rocks, if they fit better they’ll be heavier. Also material of the sand. Big rocks, small rocks. All matters.

Weight is a property given to 3-Dimensional objects.

The measure you need is cubic inches. It depends greatly on how compacted the sand is.

Loose dry sand has a mass of 1602 kilograms/cubic metres or 100.00959284437472972860113884918 pounds per cubic foot
give or take~

Thank you. So 17 cubic inches for sand. Thank you! Would it change much if it was iron or steel filings?

Iron or steel would be a bit more. Compare atomic weights of iron and silicon.

If you are looking for heavy powders Zinc dust and tungsten carbide are insanely dense and heavy powders.

Lead bird shot would give you good weight per volume, say, #9 shot.

Dry sand is too broad a description. The particles each may have a different volume and weight.
Too many variables.
Mark a square inch area on a pallet and fill the area flatly (Good Luck) and weigh the sand, weight the pallet you put the sand on. Get the sand weight. Do the math: How many squares of that weight will it take to make a pound. You will have the answer for that particular sand.

Go metric…. Dr. Lawrence is right.

But remember to measure the density of the sand (or anything you’re trying to measure by volume) Take a Xml measure and then weight it. Extrapolate the result. I work with weight, not volume because the density of the materials I use vary.

Metrics is based on water volume=weight 1 liter (1000ml) water = 1 kg. (roughly) 1kg of salt takes up less space than 1kg of water. It’s more dense. So, if I was to add 1 liter of salt to something, but what I meant to add was 1kg I would be messing up my batch. Oil, on the other hand, is lighter than water, so if I buy 1liter of oil, it’s not going to weigh 1kg. It’s usually somewhere around 900g. depending on the oil.

Of course, you’re going to be dealing with packing and that effects your volume. Your sand will be more packed on the bottom of what ever it is your’re filling, so you’re only going to be estimating this, to be sure.

Is this a trick question? Do you mean to ask how many cubic inches of sand there are in one pound? If you are talking about cubic inches of sand then the answer is simple.

pallen123's avatar

Yes @gondwanalon, cubic inches.

To determine how many cubic inches of dry sand make a pound first find out how many ounces of dry sand are in 1 cubic inch of sand. Then calculate the number of cubic inches in 16 ounces. For example: Lets say that you determine that 1 cubic inch weighs 2.1 oz. Then just set up the following relationship:

2.1 oz/1cubic inch = 16 oz/X

X = 16 oz (1 cubic inch/2.1 oz) Then X = 7.62 cubic inches/16 oz

or 7.62 cubic inches of sand per pound

Of course you will want to note the conditions at the time of measurement such as the type of sand, humidity and temperature and atmospheric pressure.
