**Easy Quantity Calculators **

**Factors:**

**This converts inches of coverage to feet of coverage**

1'' = .08 ft 5'' = .42 ft

2'' = .16 ft 6'' = .50 ft

3'' = .25 ft 7'' = .58 ft

4'' = .33 ft 8'' = .67 ft

**Estimating mulch, stone, or loam in cubic yards for square or rectangles**

**Step 1** WIDTH (x) LENGTH (in feet). Multiplied by Thickness (factor) = Cubic Feet

**Step 2 **DIVIDE Cubic Feet by 27 = CUBIC YARDS of material needed.

Example: How much loam needed to cover an area 25' wide by 50' long, 3'' thick, so 25x50=312.5 cubic feet divide by 27 = 11.57 yards.

**Estimating mulch, stone, or loam in cubic yards for circles**

**Step 1** Divide the diameter of the circle by 2

**Step 2** Multiply the radius found in Step 1 (radius) x (radius) x 3.15 x (Factor) = CUBIC FEET

**Step 3** DIVIDE Cubic feet by 27 = CUBIC YARDS of material needed.

Example: How much loam needed to cover an old pool area, 20 feet in diameter (round), 3'' thick.

20 feet divided by 2 = 10 foot radius

10 x 10 x 3.15 x .25 = 78.75 cubic feet

78.75 cubic feet divided by 27 = 2.92 yards

**Weight of materials**

**1 Cubic yard of:**

Stone, sand, stone dust, or dry loam weights approximately 3,000 lbs

Wet loam weighs approximately 3,400 lbs

Bark mulch weighs approximately 850 lbs
