**Unit Weight of sand in different unit like kg/m3, kn/m3, kg/ft3, g/cm3, cft** and lb/ft3, in this article we know about Unit Weight of M sand and river sand in kg/m3. The first thing is unit weight is as same as Specific Weight. And the specific weight of a sand is actually the product of its density and the standard gravity.

The **density of the sand is the per unit volume,** calculated in the unit of kg/m3 or lb/ft3 (pcf). The standard gravity is usually given in m/s2 of ft/s2, and on Earth usually taken as 9.82 m/s2.

In this article, details about unit weight of sand, how to determine it, and typical unit weight values of different sand types will be presented.

**Specific Weight or Unit weight of Sand**

Unit weight or Specific Weight of sand is calculated by the product of the density of sand and the standard gravity of sand. In another word, the Unit weight of sand is the ratio of the total weight of sand to the total volume of sand.

**Unit Weight of sand** is ranging between 1540 – 2000 kg/m3 based on dry and wet condition,1540 – 1600 kg/m3 is Unit Weight of dry sand and wet sand unit weight is ranging between 1760 – 2000 kg/m3.

**Unit weight, is usually determined in the laboratory** by measuring the weight and volume of a relatively undisturbed soil sample obtained from a brass ring. Measuring the unit weight of soil in the field may consist of a sand cone test, rubber balloon, or nuclear densometer.

The typical weight of sand is about **2,700 pound** per yard, **110 pound** per cubic foot, **17 pound** per square foot, **13.5 pound** per gallon, **1,600 kg** per cubic meter, 80 kg per square meter, **150 pound** per square yard. This can vary as per moisture contents.

**How to calculate Unit Weight of sand?**

How to Calculate the Unit Weight of Sand? To calculate the unit weight of sand, we have to know some information, the volume of one unit of sand, the composition of the sand, and the mass densities of each component. Sand weight calculator also has to be taken.

1) We have to know the constituent materials of the substance. In the Sand, assumed it was a mixture of the minerals olivine and basalt. For other types of sand, may have mixtures of quartz, gypsum, or silica.

2) We have to know the volumetric percentage of each constituent material in one unit of the substance.

3) We have to know the mass densities (or specific gravity) of the constituent materials.

4) From the volume and the mass densities, now we can determine the mass of each material. Now by adding the masses to get the total mass of the substance, which is proportional to the total weight.

**Unit Weight of sand in different unit like kg/m3, kn/m3, kg/ft3, g/cm3, cft and lb/ft3**

**Unit Weight of sand** is ranging between 1540 – 2000 kg/m3 based on dry and wet condition,1540 – 1600 kg/m3 is Unit Weight of dry sand and wet sand unit weight is ranging between 1760 – 2000 kg/m3.

**Unit weight of sand is around 1680kg/m3** or measured in other units- 16.4808 in kn/m3, 104.832 in lb/ft3, 1.68 in g/cm3 and 47.54 in kg/ft3.

**Unit weight of M sand is around** 1750kg/m3 or measured in other units- 17.16 in kn/m3, 109.2 in lb/ft3, 1.75 in g/cm3 and 49.52 in kg/ft3.

**Unit weight of river sand** is around 1710kg/m3 or measured in other units- 16.78 in kn/m3, 106.7 in lb/ft3, 1.71 in g/cm3 and 48.40 in kg/ft3.

**Conclusions:**

The typical unit weight of sand is about **2,700 pound** per yard, **110 pound** per cubic foot, **17 pound** per square foot, **13.5 pound** per gallon, **1,600 kg** per cubic meter, 80 kg per square meter, **150 pound** per square yard. This can vary as per moisture contents.
