## MATERIAL CONVERSIONS

### 1 Cubic Yard Equals:

27 cubic feet

(54) ½ cubic foot bags

(36) 5 gallon buckets

(23.5) 1.15 cubic foot rubber mulch bags

(13.5) 2 cubic foot mulch bags

(9) 3 cubic foot mulch bags

### Tons Per Cubic Yard: Gravels

Lava Rock (all) = .5 tons (1000 lbs.) per cubic yard

Eastern Sunrise = .9 tons (1800 lbs.) per cubic yard

Crimson = 1.1 tons (2200 lbs.) per cubic yard

Rock (57 & 89) = 1.2 tons (2400 lbs.) per cubic yard

Lime Rock (919) = 1.25 tons (2500 lbs.) per cubic yard

River Rock (all) = 1.325 tons (2650 lbs.) per cubic yard

Granite (all) = 1.325 tons (2650 lbs.) per cubic yard

Marble (all) = 1.35 tons (2700 lbs.) per cubic yard

### Cubic Footage Per Ton Of Building Stone & Flagstone

15 cubic feet per ton*

or 133 lbs. per cubic foot*

*Note: The true cubic footage weights are 145-160 pounds per cubic foot, for solid unbroken stone, or about 13 cubic feet per ton on average. Being unlikely that you will be able to stack the stone that tightly, using the true numbers would result in an erroneous quantity being delivered to your site, further resulting, upon completion of the job, in hostile thoughts being pointed in our general direction, therefore, we have adjusted this number to be more consistent with reality in order to circumvent those aforementioned hostile thoughts and have happy customers in perpetuity. So you don’t have any leftovers we thought it best this way.

## MATERIAL FORMULA BASICS

Convert all measurements from feet and inches into their decimal equivalent in feet only.

Example: You have a measurement of 6′ 9″

(9″/12″) + 6′ = 6.75′

### Formulas

Square Footage (squares & rectangles)

(length x width) = Square Footage

Square Footage (circles)

(radius x radius) 3.14159 = Square Footage

Square Footage (right triangles)

(1/2 x width) length = Square Footage

Cubic Footage

(square footage x depth) = Cubic Footage

Cubic Yardage

(cubic footage / 27) = Cubic Yardage

Circumference of a circle

(diameter) 3.14159 = Circumference

## MATERIAL CALCULATE QUANTITY NEEDED

### Gravel, Mulch, Sand & Soils

Figure out the square footage to be covered

Multiply the square footage by the depth desired to get the cubic footage

Divide the cubic footage by 27 to get the cubic yards needed

Example: A rectangular landscape bed is 12′ 8″
long and averages 5′ 6″ wide and the depth desired is 2 ½” deep.

(12.66′ x 5.5) = 69.3 square feet

(69.3 x .208) = 14.414 cubic feet

(14.414 / 27) = .534 cubic yards needed

### Flatwork (Patios, walls, etc.)

Figure out the square footage to be covered

Get the coverage per ton of the product desired

Divide the square footage needed by the coverage per ton

Example: A patio or wall is 20′ long and 8′ wide
or high and you would like to use Buff Patio flagstone that has a
coverage of 110-130 square feet per ton.

(20′ x 8′) = 160 square feet

Average coverage is 120 square feet per ton

(160 / 120) = 1.333 tons needed

### Stacked Stone Walls & Waterfalls

Determine the average length, the average height and the average width of the stone in feet

Multiply the length by the width by the height to get the cubic footage

There
is about 15 cubic feet in a ton of building stone or flagstone so
divide the cubic footage by 15 to determine the quantity of stone needed
in tons

Example: A 20′ long stacked stone wall that is 1′ thick and 2′ tall

Length = 20′, Height = 2′, Width = 1′

(20′ x 2′ x 1′) = 40 cubic feet

(40 / 15) = 2.667 tons of stone needed
