Hello,
Can someone please explain to me what a 5gallon, 15gallon, etc. pots are equivalent to pots measurements in inches or centimeters?.
I thank you beforehand. Bye bidwi.

ok I'll try.

5 gallons (US DRY Measurement) equals 1,344 cubic inches, or .77778 cubic feet, or 22,024.419 cubic centimeter

http://www.onlineconversion.com/volume.htm is the conversion website I use for those kinds of things. I hope this will help you some.

This info is from Iowa State university Extension.

Round pots are measured in inches using the inside diameter of the top rims of the pots. Capacity is the amount of soil needed to fill up the pots.

Measurements/Capacities
Inches [Centimeters] = Cup/qt/gal [liters]
-----------------------------------------

3" [7.60cm] = 1 Cup [.24 liter]

4" [10.16cm]= 2.5 cups [0.60 liter]

5" [12.70cm] = 1 quart. [.94 liter]

6" [15.24cm] = 2.5 quarts. [2.35 liters]

8" [20.32cm] = 1 gallon [3.76 liters]

10" 25.40cm] = 2.25 gallons [8.46 liters]

12" [30.48cm] = 3.5 gallons [13.16 liters]

14" [35.56cm] = 6 gallons [22.56 liters]

Hope this helps.

That was an awesome post Thank You!
