    How to know exactly how many lgallons/itres your round plant pot is ...

    Hi.

    The workers at the place where i bought my pots didn't know how many litres they were, i judged they must be about 7 litres since they were 8" tall, 8" across the top and 6" across the bottom.

    I wanted to find out how much they really held so i looked for and found a formula that gives you the volume of a plant pot (in maths it's called a frustum of a cone), it gives the volume in cubic centimetres :

    Calculate volume of a truncated cone and its surface area (mobile)

    I plugged in my plant pots numbers and the result is 19,373.154697 cubic centimetres.

    I then type in 'convert 19,373.154697 cubic centimetres to gallons' and got the answer 4.26149651 gallons, in litres this is 19.373 litres !

    There's no way my plant pot is 19 litres at that size is there ? Am i missing something ??


    Cheers,

    nibs.

    I just sealed the bottom of my pot using clingfilm inside, i filled it with 5 litres of water.

    Does 5 litres of water equate to 5 litres of soil ?

    Hi Nibs and welcome to Cannacom!

    Try this link out and see what you get?

    Liters To Cubic Inches (l to in3) Conversion
    Just a small question though: Why on 'earth' would you want to equate your dirt to water or: liter to cubics'?pr

    Wink Standard size

    8" dia, 8" high is a 1 gallon pot.

    Nominally speaking.

    Thanks Weez and pain, it was, of course, human error

    I put the top radius as the bottom radius and vice versa so the formula didn't work.

    Now i've done it correctly and it comes out as 5 litres so yes about a gallon.

    Hope that's not too small for my plants i thought i'd bought 6.5L pots.


    Cheers,

    nibs.
