The first thing is Unit weight is as same as Specific Weight. And the specific weight of a material is actually the product of its density and the standard gravity. The density of the material 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 9.81 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. Unit weight or Specific Weight of sand is calculated by the product of the density of sand and the
standard gravity of sand. According to the US customary measurement system, dry weighs 1.631 gram per cubic centimeter, this density is equal to 101.8 pounds per cubic foot [lb/ft³]. Different Sand Type DensityThe following table represents the typical dry density values for different types 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, 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. How to Calculate the Unit Weight of SandTo 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.
Unit Weight of Different Types of SandThe followings are the typical value of different types of sand.

Use this calculator to estimate how much sand in volume (cubic ft, cubic yards, or cubic meters) or weight (tons & pounds, tonnes and kilograms) you would need. It uses conventional sand density. Quick navigation:
Calculating how much sand you needMany builders and gardeners are faced with calculating or estimating the amount of sand they need to fill a given space with sand. Our sand calculator is of great utility in such cases, but you should keep in mind that the results will only be as good as the measurements entered. The calculation process is as follows:
There is finer and more coarse sand, so the density, measured for dry sand in kg per cubic meter or pounds per cubic feet, of your particular shipment may vary. For this reason, and due to potential loses / waste, you should consider buying 5-6% more sand than estimated so you don't run just short of what you need in the end. Square or rectangular areaThe volume formula for a rectangular (or square) box in cubic feet is height(ft) x width(ft) x length(ft), as seen in the figure below:  For example, to fill a box with a width of 3ft and a length of 6ft, to a depth of 1ft, you need to multiply 1ft x 3ft x 6ft = 18ft3 (cubic feet) of sand. Round areaIf the area you want to cover, or the shape you want to fill is round, the calculation is a bit different: The volume of a figure with a round foundation is its height times the area of its foundation. To calculate the foundation area we need its diameter, since the formula is π x r2, where r is the radius, or diameter/2. Irregularly shaped areaIn case the area you are calculating has an irregular shape what you want to do is divide it in several regularly-shaped sections, calculate their volume and sand requirements and then sum them up together. In case you end up needing to do this for a large number of sections, you might use our summation calculator. Sand basicsSand is a naturally occurring granular material which is composed of finely divided rock and mineral particles, rounded and polished to a varying extent. Sand can be thought of as finer gravel, or coarser silt. In some cases, "sand" refers to a textural class of soil, that is - a soil which has more than 85% of its mass comprised of sand-sized particles. Sand is a renewable resource in the long run, but in human timescale it is practically non-renewable. Sand is a major component of concrete and due to the high demand for concrete for construction, suitable for concrete sand is also in high demand. The most common constituent of sand in inland continental settings and non-tropical coastal settings is silica quartz (silicon dioxide - SiO2). The second most common type of sand, mostly encountered in islands and near the sea, is calcium carbonate which is created by various life-forms, like coral and shellfish. Of course, the exact composition will vary depending on local rock sources and conditions during the formation of the pebbles. Sand for domestic or garden use is usually sold in small packets of several pounds / kilograms, and for larger projects in bags of 40, 60 or 80 lbs - 25kg or 50kg in Europe and other places. For construction work, concrete mixing, etc. it is sold by the tonne and comes in trucks. Types and grades of sandContrary to what you may think, there is more than one type of sand, by the size of its pebbles and it's intended use [2]. Selecting the right type and size is crucial, as some sands have a different application than others. Sand types
Standard sand, in addition, shall be light grey or whitish color, should be free from silt and the grains should be angular, but a small percentage of flaky or rounded particles are permissible. Some manufacturers express the grade and type of the sand in other ways, e.g. "river sand" (a.k.a. "sharp sand", "builder's sand", "grit sand", "concrete sand"), "masonry sand", "M-10 sand" (granite sand), "play sand", each being finer and more expensive than the previous one. What is the density of sand?The density of typical sand is 100 lb/ft3 (1600 kg/m3). This corresponds to moderately damp sand and is the number used in the calculator. How much does a yard3 of sand weigh?A cubic yard of typical sand weighs about 2700 pounds or 1.35 tons. A square yard of a sandbox with a depth of 1 foot (30.48 cm) weighs about 900 pounds (410 kg) or slightly less than half a ton. The water content of the sand is assumed to be moderate. How much does a cubic meter of sand weigh?A cubic meter of typical sand weighs 1,600 kilograms 1.6 tonnes. A square meter sandbox with a depth of 35 cm weighs about 560 kg or 0.56 tonnes. The numbers are obtained using this sand calculator. How much is a ton of sand? A ton of sand is typically about 0.750 cubic yards (3/4 cu yd), or 20 cubic feet. Sand is assumed relatively damp, since adding water can increase or decrease the density of the sand considerably (e.g. if it was raining or if you dig up and leave sand under the sun so water evaporates).How much is a tonne of sand?A tonne of moderately damp sand typically fills about 0.625 m3 (cubic meters). It can be more or less dense depending on water content and the size of the sand particles. Ton vs tonne, tons vs tonnesWhen calculating the sand's weight, make sure you do not confuse the tonne (metric ton) with the ton (short ton). The first one is used by all countries in the world and is defined to be equal to 1000 kg by the international body of standardization. The ton is currently only used in the United States and is equal to 2000 pounds (2000 lbs). The difference between the two is not huge but can quickly add up to a significant number as the amount increases. References[1] Krinsley D.H., Smalley I.J. (1972) "Sand", American Scientist 60:286-291 [2] ASTM C-778 - 17 "Standard Specification for Standard Sand" What does 1 pound of sand weigh?One pound of beach sand converted to gram equals to 453.59 g.
What does dry sand weigh?Dry sand weighs between 2600 to 2900 pounds per yard or 1.3 to 1.45 tons per yard. The unit weight of dry sand is between 96 – 108 pounds per cubic foot, which equals around 2600 – 2900 lb per cubic yard.
Is dry sand heavier than wet sand?So equal volumes of wet and dry sand would not weigh the same; the wet sand would weigh more because it has more mass, the mass of the water in-between the sand and the mass of the sand itself.
How much does a 5 gallon bucket of sand weigh?Here is how much sand these item will hold: 5 gallon bucket = 70 pounds of dry clean play sand (80 to 90 lbs if wet sand) Large Plastic Garbage can (50 or 55 gallon size) = 700 to 770 lbs if play sand is dry.
