Estimate Square Footage:

Width (feet) x Length (feet)



Other handy garden formulas:

* To determine the area of your yard, multiply the length by the width (both in feet). The answer will be in square feet.

* To determine the diameter of a circle (such as a tree trunk): circumference divided by 3.14. To measure the circumference of a tree trunk, wrap a fabric tape measure (or a piece of string) once around the trunk, about waist high.

* To determine the area of a circle: 3.14 times the radius squared. When measuring the area beneath a tree, the radius can be calculated by extending the ruler from the trunk to the drip line (the furthest extension of the tree branches).

* Approximately one cubic yard of mulch will cover 100 square feet with three inches of mulch. A more exact formula: Area (in square feet) times depth of mulch or compost you want to apply (in inches) divided by 324 will give you the number of cubic yards to purchase.  Also see our mulch calculator.

*27 cubic feet equal one cubic yard.

* Three teaspoons equal one tablespoon. Two tablespoons equal one ounce. 16 tablespoons (eight ounces) equal one cup.
