Generally gravel quantity measured in volume and their mass, volume of gravel based on Imperial or US customary measurement system measured in cubic yard, cubic meter, cubic feet and cubic inch. Mass of gravel generally measured in kilograms, pounds and tons.

During the estimating gravel and crushed stone quantity for your construction work, preparing of concrete mortar, you can do gravel calculation to know about how much gravel do i need and how much gravel in truck you can load. Gravel calculator will help you in determining quantity and volume of gravel

Gravel is made of rock is to build roads, path, driveway, Patio, pedestrian, pavement, pathways, roadways, landscaping, and etc.

Gravel is categorized according to their size, size more than 5mm put in the category of gravel, it is formed of igneous rocks. It is categorized as fine gravel (4 – 8 mm), medium gravel (8 – 16 mm), coarse gravel (16 – 32 mm), pebbles (32 – 64 mm), cobbles (64 – 256 mm) and Boulder more than 256mm.

You are looking to buying gravel and crushed stone for your construction work, if you want to apply them in normal depth 50 mm for your driveway and 35 mm depth normally in pedestrian pathway, you need to know how much gravel do i need and you should purchase and you can load in your vehicle.

Most of gravel supplier which are available nearly to you, will give you option to deliver gravel and crushed stone at your homes, for this they should cost some money for transportation.

Weight of gravel and stone depends on the rocks type, loose and dense condition, compact, moisture content, dry and wet condition. Typical gravel density (dry) is between 1520 and 1680 kg/m3 (95 to 105 lbs/ft3). If it is mixed with sand the density is around 1920 kg/m3 or 120 lbs/ft3.

A cubic meter of typical gravel weighs 1,680 kilograms 1.68 tonnes. A square meter of gravel with a depth of 5 cm weighs about 84 kg or 0.084 tonnes. Gravel used as landscaping materials, generally depth of landscaping projects will be 50mm, 80mm and 100mm thick.

Gravel calculation/ gravel calculator- how much gravel do you need

To calculate amount of gravel you might need for your projects, generally you calculate volume of excavation or backfill by multiplying length, width and their depth which is equal to volume of required gravel quantity.

Cubic yard gravel calculator: Yards of gravel = Cubic feet of excavation × 0.037. To calculate how many cubic yards of gravel you will need for excavation, multiply the total cubic feet needed by the 0.037 to get cubic yards of gravel.

Cubic meter gravel calculator: cubic meter of gravel = Length × width × height in meters. To calculate how many cubic meters of gravel you will need for excavation, multiply the length, width and height to get cubic meters of gravel needed.

Calculate the volume of gravel needed which is equal to volume of excavation or backfills, you can do gravel calculation/ calculator in following methods:-

1) determine the length width and depth of landscaping, it may be in cuboidal round or irregular shape, suppose length of cuboidal shaped landfill = 5m, width of excavation = 4m and depth = 5cm

2) Calculate Area of excavation by multiplying Length and width, such as 5m × 4m = 20 m2

3) Convert depth 5cm into meter = 5/100 = 0.05m

3) Calculate volume of excavation by multiplying area and depth, such as 20m2 × 0.05m = 1m3

4) the volume of gravel needed is equal to the volume of excavation or backfill you need to fill, so you will need about 1m3 (1680kg, or 1.68 tons) of gravel and stone to fill 5m × 4m × 5cm dimension of your excavation or backfill.

How much gravel do i need for 50m2

A cubic meter of typical gravel weighs 1,680 kilograms 1.68 tonnes. A square meter of gravel with a depth of 5 cm weighs about 84 kg or 0.084 tonnes.

To calculate how many cubic metres (m3) of gravel you will need to use, firstly measure the area of the garden to be covered.

The width x length will give you the area in square meters (m2). eg. an area measuring 10m x 5m = 50 m2. Then multiple your square meter measurement by 0.05 ie. 50 x 0.05 = 2.5m3 of product required for good surface coverage.

Area of garden (m2) x 0.05 = volume of gravel required (m3). This will cover your garden in gravel to a depth of 50mm which is recommended to retain valuable soil moisture and inhibit weed growth.

You would need 2.5m3 (4200 kilo, or 4.2 metric tons) of gravel for 50m2 area to cover at standard depth of 5cm (50mm), 1.75m3 (2945kg, or 3 metric tons) of gravel at 3.5cm (35mm) thick, 4m3 (6730kg, or 6.7 metric tons) of gravel at 8cm (80mm) thick, and 5m3 (8400kg, or 8.4 metric tons) of gravel at 10cm (100mm) thick.

You might need 2.5m3 (4200 kilo, or 4.2 metric tons) of gravel to cover 50m2 area at standard depth of 5cm (50mm), 1.75m3 (2945kg, or 3 metric tons) of gravel at 3.5cm (35mm) thick, 4m3 (6730kg, or 6.7 metric tons) of gravel at 8cm (80mm) thick, and 5m3 (8400kg, or 8.4 metric tons) of gravel at 10cm (100mm) thick.
