it references to the density of sand,
Density of sand can vary depending on the grain size and moisture content and how tightly it is compacted
If you dont need very accurate densities the following should help

Sand, wet, packed
2082
Sand, dry
1602
Sand, loose
1442
Sand, rammed

That would be good project for you - to get a cubic metre of sand and count the grains.
About one and 1/2 metric tons. But the weight varies.

1750-2400 kg per cubic meter of concrete

About One
With dry sand. 1.602 tonnes
depends of the mass of what u are measuring
Since about 20 grains of sand lined up is 1cm, then I can use the volume formula (bwh) and subsitute in 20 grains of sand. 20*20*20=8000. There are about 8000 grains of sand in a cubic centimeter.
it is 100 bags of sand/ballast
4.12g/cm cubed
100
The weight varies; but if it's dry sand, the cubic meter will weigh around 1500 kilos.
It isn't clear what "units" you are talking about.
