# pot size in CM unit? ### Help Support Homebrew Talk: #### zzyvba

##### Active Member
Why would someone be interested in pot's length? I went to some local stores to buy a boiling pot and found that all their sizes were in CM! 40x40CM 40x35CM...etc.

I searched for unit converters .. but didn't find any. How to convert "size" from CM to gallon?

Help!

3785.4 cubic cm per gallon.
Volume of a cylinder equals (pi X r^2)Xheight
Example: 40x40cm

V=(3.14X20^2)X40
=50240 cubic cm
Divide by 3785.4 cubic cm per gallon=13.27 gallons

You just have to know which measurement is which, diameter or height, to figure out other volumes.
Example: 40 X 35cm.
