Gravel or coarse aggregate is one of the most important construction material required in every civil construction work, for landscaping projects, gravel rods, its required for fill the excavation area, used as backfills, required for preparing the concrete mix, it will be in round or oval, angular, pea size shaped gravel.

Density of gravel is unit weight define by mass by volume, measured in kg/m3, pound/ cubic yard, kg/ cubic feet, pound per cubic feet. In this article we know about “how do I figure out how much gravel I need?”. Required gravel quantity calculate in volume and mass. Volume of gravel measured in cubic meter and cubic feet. Mass of gravel measured in tonne or in kg.

**How do I figure out how much gravel I need?**

Calculate gravel for your garden: if your an area measuring 5m x 4m = 20 m2. Then multiple your square metre measurement by 0.05 ie. 20 x 0.05 = 1m3 of product required for good surface coverage. This will cover your garden in gravel to a depth of 50mm which is recommended to retain valuable soil moisture and inhibit weed growth.

Thickness is important factors to determine how much gravel do you need, if you choose a 10mm aggregate such as Premium Quartzite Pea Gravel 10mm or Cottage Cream Gravel 10-20mm, you may want to lay it to a depth of around 30-40mm. If, however, you are buying gravel or granite chippings for driveways, you will probably need to lay it up to a depth of around 50mm-60mm.

To figure out how much gravel I need?, To figure out quantity of gravel for driveway in cubic feet, multiply the length (in feet) by width (in feet) by depth (in feet). For cubic yards, multiply the total cubic feet by 0.037. Because one cubic yard of gravel is equal to 1.35 tons, you can multiply your total cubic yards by 1.35 to convert this measurement to tons.

**How do I figure out how much gravel I need in cubic feet**

To figure out how much gravel do i need for your garden in cubic feet: if your an area measuring 15 feet x 12 feet = 180 square feet. Then multiple your square feet measurement by 0.166 ie. 180 x 0.166 = 30 cubic feet of product required for good surface coverage.

**Formula for quantity of gravel in cubic feet = Length in feet × Width in feet × Thickness in feet.**

For example: if your garden are measuring 20 feet in length by 15 feet in width by 2 inches in depth. Then total cubic footage of gravel you will need = 20 × 15 × 0.166 = 50 cubic feet.

**How do I figure out how much gravel I need in cubic yard**

To figure out how much gravel do i need for your garden in cubic yard: simply multiply Length in feet × Width in feet × Thickness in feet to get cubic feet. Then multiply your cubic footage by 0.037 to get gravel quantity in cubic yard.

**Formula for quantity of gravel in cubic yard = (Length in feet × Width in feet × Thickness in feet) × 0.037.**

For example: if your garden are measuring 10 feet in length by 10 feet in width by 2 inches in depth. Then total cubic footage of gravel you will need = 10 × 10 × 0.166 = 16.6 cubic feet. Then multiply your cubic footage by 0.037 to get cubic yard = 16.6 × 0.037 = 0.62 cubic yard.

**How do I figure out how much gravel I need in cubic meter**

To figure out how much gravel do i need for your garden in cubic meter: simply multiply Length in meter × Width in meter to get area in square meter. Then multiply your area by 0.05 to get gravel quantity in cubic meter.

**Formula for quantity of gravel in m3 = (Length in meter × Width in meter × 0.05**

For example: if your an area measuring 10m x 4m = 40 m2. Then multiple your square metre measurement by 0.05 ie. 40 x 0.05 = 2m3 of product required for good surface coverage.

**How do I figure out how much gravel I need in tonnes**

To figure out how much gravel do i need for your garden in tonnes: simply multiply Length in meter × Width in meter × depth in meter to get volume of gravel quantity in cubic meter. Because 1m3 of gravel equals 1.68 tonne, so, multiply your m3 by 1.68 to get tonnage of gravel.

**Formula for quantity of gravel in tonne = (Length in meter × Width in meter × depth in meter) × 1.68**

For example: if your an area measuring 8m x 4m × 50mm = 1.6 m3. Then, 1.6 × 1.68 = 2.688 tonnage of gravel product required for good surface coverage.

**How do I figure out how much gravel I need in ton**

To figure out how much gravel do i need for your garden in tons: simply multiply Length in feet × Width in feet × Thickness in feet to get cubic feet. Then multiply your cubic footage by 0.037 to get gravel quantity in cubic yard. Your cubic yard multiply by 1.35 to convert this measurement to tons.

**Formula for quantity of gravel in tons = (Length in feet × Width in feet × Thickness in feet) × 0.037 × 1.35 .**

For example:- if your garden are measuring 15 feet in length by 12 feet in width by 2 inches in depth. Then total cubic footage of gravel you will need = 15 × 12 × 0.166 = 30 cubic feet. Then multiply your cubic footage by 0.037 to get cubic yard = 30 × 0.037 = 1.11 cubic yard. Multiply your 1.11 yard by 1.35 to convert this measurement to tons = 1.11 × 1.35 = 1.5 tons.

**Conclusion:**

To figure out quantity of gravel for driveway in cubic feet, multiply the length (in feet) by width (in feet) by depth (in feet). For cubic yards, multiply the total cubic feet by 0.037. For tons, multiply the total cubic yards by 1.35.
