This may sound like a stupid question but i am trying to find out how much in weight a cup full would be. I intend to send a Soil Sample to A&L Canada Laboratories for analysis and they ask for a cup full of soil to be sent for sampling. A cup full here is only about 2 Ounces but that cannot be the same volume as the cup full A&L Canada Lab's are asking for.

Thank's in advance for any replies.

1 cup = 250 ml. If it were water it'd weigh 250 grams. Asume soil is half the weight of water, so about 125 grams? This is just a guess, I'll see if I can get a cup of soil weighed today before I leave work.

Liquid or Dry....A liquid cup is normally 8 ounces

it depends on what the density of the soil is.
light fluffy dry soil will not weigh as much as heavy compact wet soil.

doesn't the post office weigh it for you and then tell you what the cost is ?

As gordon said, it depends on the soil, but I checked it out, soil from my garden (sandy loam), completely dry, 250 ml of soil weighed just short of 200 grams. We added some water to where it looked like average damp soil, it weighed 230 grams, but it also compacted some, so additional soil should have been added to make it a full 250 ml. The Lab here is closed now though so this is the best I can do, hopefully I helped a little bit.

Thanks for the replies so far chaps. I decided to Email A&L Canada Lab's and ask them what their interpritation is of a 'Cup' of soil and they came back and informed me it was 1 to 2 Lbs in weight. Surely this cannot be correct and a Lab does not require that much soil to carry out an analysis. The soil i need to Ship over is completely dry and is a medium sandy loam type.

Any suggestions from people here, who have submitted soil to A&L Canada Laboratories for analysis, would be greatly appreciated also.

Weight has no bearing on volume unless we know the bulk density (specific gravity) of the item being measured.

If we're trying to discover the weight of a soil sample for calculating postage, we kind of can't. The moisture content will vary from one sample to the next so the weight for two identically *sized* sample will be different.

Try weighing a few soils of differing moisture but identical volume. Purchase enough postage for the heaviest sample plus 10%.

Here in the US the US Postal Service has scales at all the branches.

Thanks again for the additional replies Chaps. Hans, thank you for that calculation/conversion table, the weight of 8 Ounces for 1 Cup sounds most realistic. Don, same as with Hans, more realistic than the 1 to 2 Lbs i was asked for. Steve, i know exactly where you are comming from with your comments. I am going to get as much of the packaging & neccessary forms all together and put an 8 Ounce weight in with them and weigh it all on my postage maul scale. That way i will be able to get a postage quote.

Once again a very big thanks to everyone for their input.
