I find its hard to buy the most for my money when I don't know how much I'm getting. When I try to buy potting soil, one store has a package measured in cubic feet then another has it measured in qts. Then another has it in liters. My math skills are not the best to calculate. Help me please?

Quarts is a measure of volume; pounds is a measure of weight. There is no standard conversion. The rate of quarts per pound will actually depend upon the density of the soil. A denser soil will weigh more; and therefore convert to less quarts per pound.

Based on my research on potting soil, each quart weights approximately 0.875 pounds; thus, 10 pounds means roughly 11.43 quarts. 10 Quarts equals 9.4 Liters. There are about 25 and 3/4 dry quarts in a cubic foot. A 20 dry quarts package of potting soil is approximately 3/4 of a cubic foot. Still confused? Potting soil is usually less expensive in the larger bags. Here's how many containers one cubic foot of potting soil will fill: Standard round pots; 2 1/4-inch: 256, 4-inch: 48, 8-inch: 6. Hanging baskets; 8-inch: 11, 10-inch: 5. Seedling trays; 20-row tray: 11. Germination flats; Standard flat: 7.

Hope this helps!
