"1 cubic meter" is a perfectly good 'quantity'. If the 'quantity' you want is the weight instead, then you need to know a unit weight or density for sand, in order to convert a volume to a weight.
Sand, dirt, gravel and even concrete is measured by the cubic yard and each cubic yard is 1 unit. therefore 1 unit of sand = 27 cubic feet Hence 1 unit of sand = .772 cubic meters
A liter is a unit of volume not weight, therefore to determine how much a liter weighs it depends on what you're measuring. A liter of water has a different weight than a liter of sand and so on.
Sand, wet - 1920 kg/m³ Sand, wet, packed - 2080 kg/m³ Sand, dry - 1600 kg/m³ Sand, loose - 1440 kg/m³ Sand, rammed - 1680 kg/m³ Sand, water filled - 1920 kg/m³

2000 pounds.
millimeter is a unit of distance while milligram is a unit of weight
1 ton of quartz sand weighs 2,000 pounds, and oranges are colored orange.
The SI unit of measurement for weight is the newton.
The atomic weight unit is 1/12 from the atomic mass of isotope 12C.
That question cannot be answered, because you ask for a length or distance unit in yards and than for weight in metric tonnes. Length and weight does not go together. Sand is so very different as a naturally occurring granular material of finely divided rock and mineral particles. Sand particles range in from 0.0625, or 1⁄16 mm to 2 millimeters in diameter. An individual particle in this range size is termed a sand grain. The next smaller size class is silt, that are particles smaller than 0.0625 mm and down to 0.004 mm in diameter. The specific weight, also known as the unit weight, is the weight per unit volume of a material. The density of the material, mass per unit volume, is measured in kg/m3. You have to know many more parameters. Is the sand wet or dry. What is the weight of the water in it? Even if you meant "cubic" yards, the calculation of a weight cannot work. The question: "How many cubic yards of pure water make a metric tonne?" is easy to answer.
