Examples
- You just put in a new 10 x 30 ft garden. You’re going to amend the soil by digging in a 3 inch layer of compost. How much compost will you need? On the calculator, you would enter:
– 300 for Square Feet (10*30)
– 3 for Inches Deep
– Press the Yards button, and you will see that you need 2.77778 yards (cubic). - Now, using the example above, let’s say you will round the yards to 3. How many inches of compost can you dig into your new garden?
– Leave Square Feet the same, just enter 3 for Yards and press Inches.
– You will be able to dig a 3.24 inch layer of compost into your garden. - Suppose you can get a great deal on mulch, but you can ony get 10 yards at that price. You want to know how many square feet that mulch will cover if you make it 4 inches deep. You would enter:
– 4 for Inches Deep
– 10 for Yards (cubic)
– Press the Square Feet button, and you will see that you could cover 810 square feet 4 inches deep with that mulch.
