So, you’re landscaping an area with a wish to cover the space with gravel and are now wondering how many tons of gravel you need for each yard of your lawn.
At this stage the only thing you know is the square footage area you need to cover with gravel. So, how’d you tell the supplier about the weight of gravel, since they take orders in weight instead of area.
Here in this guide we’ll explain about everything you need to know for knowing how many yards are in a ton of gravel.
So, let’s get started:
Different materials – different units
Dealing with building materials and supplies in renovation project seems a daunting task. Ordering building materials need accurate estimating to avoid unnecessary surprises. Some building materials are measured in units of area, length while some are measured by weight. When it comes to gravel, the industry takes it by estimates it by volume but the suppliers take it by weight.
Gravel is a coarse aggregate having widely uses in various construction and renovation projects. It is used for construction of roads, walkways, railway ballasts, in foundation, concreting and hence most widely used in construction industry. Therefore, before buying gravel, you must know the right quantity. Gravel is always estimated in unit of volume.
There are various units, that are in used in construction industry which includes:
Meter: Cubic meter, square meter.
Foot: Cubit Foot, square foot.
Inch: Cubic inch, square inch.
Yard: Cubic Yard, square yard.
Since there are various units in construction industry for measurement of quantity of material so there is always needed to convert one unit to another unit for efficacy of project.
Yards to Ton unit conversion
Here, we have to deal with unit conversion of yards to ton. Therefore, we will consider these units and their conversion.
Yard is a unit of length and it measure 1-yard equals to 36 inches or 3 feet.
Ton is the unit of weight. In SI unit 1-ton measure weight equal to 1016kg. While in Indian or Asian market 1-ton equals weight of 1000kg and it is practically used in our construction industry.
Conversion of Yard to Ton:
Since yard is the unit of length while ton is the unit of weight so technique is needed to convert this unit of length to unit of weight and this unit conversion is totally dependent on the density of gravel used. As, this density of material changes this yard to ton conversion factor also changes.
Number of yards in ton of gravel
As in construction industry, gravel is available in various shape and size therefore density of gravel is also different for different type of gravel and conversion factor of yard to ton is gravel also varies. Let us consider following type of gravel and their conversion factors.
It has density of 85lb/ft^3. To find conversion factor for this loose gravel consider
Given density is 85lb/ft^3. By converting this density into cubic yard and find its weight as.
per cubic yard
So, ton per cubic yard
Therefore, it is found that 1 cubic yard of gravel = 1.15 tons
So, in 1 ton of gravel there are yards
Thus 0.87 is the conversion factor of number of yards in ton. If there are 3 tons of loose gravel then, Number of yards = 3 x 0.87 = 2.61
½ to 2-inch size dry Gravel
It consists density of 105 lb. ft^3. Which shows 105 pounds weight in per cubic feet. By converting in cubic yard, we will get 2835 pounds per cubic yard. As, 2000 pounds equals 1 ton. Therefore 2835 pound per cubic yard equals to 1.42 tons in 1 cubic yard. As we did in above procedure. So, in short, for ½ to 2-inch wet gravel
1 yard of gravel = 1.42 tons
So, number of yards in 1 ton = 1/1.42 = 0.704
In 3 tons of gravel there are 3 x 0.704 = 2.11 yards.
How’d you do measurements for your home renovation project?
Determining the area
So, the first step is to determine the area that you wish to cover with gravel. For that, take a meter tap and ask someone to help you while stretching the tape measure.
You need to determine the longer dimension of your lawn or area. Take note of the length on a piece of paper. It is always helpful to draw a rough sketch with dimensions for better understanding later on.
Before leaving the tap measure, mark the spots on the field so you clearly know which dimension has been taken off. Now move on to the other side of the field and determine the width of the area. Once you have the lengths and width on the piece of paper; it’s time to do the reckoning.
We have the lengths and the widths, so we can multiply the two to get the area to be covered with gravel.
So, area for gravel = length x width
Determine the volume
For the volume, we need to determine or estimate the depth for the layer of gravel. Generally in landscaping projects, the common depth is 1 to 2 inches. Now we can multiply the three dimensions to determine the volume of required gravel.
so, volume of gravel = length x width x thickness
Convert Yards to Tons in Gravel
I recommend you to convert inches or feet to yards as per the conversion factor above. Once, you’ve got the cubic yards; you can easily relate that to tons for ordering supplies.
Let’s say your area of landscaping came out as 100 cubic yards. As a general rule of thumb, landscapers multiply this with 1.4 and say you need 100 x 1.4 = 140 tons of gravel for covering the space with gravel.
But for different types of gravel in terms of quality; the weight can be different.
So, how to Convert Yards to Tons in Gravel for different types?
Here’s how they weigh per cubic yard;
- Wash gravel – 2,835 pounds per cubic yard
- Screened stone (fine quality) – 2,970 pounds per cubic yard
- Sand – 2,700 pounds per cubic yard
So, whatever quality of gravel you wish to choose, use the correct density factor for estimating yards in ton of gravel.
A pro tip
A 10-wheel dump truck carries 12 to 20 tons of gravel or around 8 to 10 yards depending on the rock size and type.
Yard is the unit of length and ton is the unit of weight. To find number of yards in one ton, it is dependent on density of material and procedure for finding number of yards in one ton is stated above.
