Anyone know how to calculate gallons?

payley Jan 06, 2004 08:36 PM

I have a tank and I want to calculate exactly how many gallons it is. Is there a way to tell based on length/width/height? If so, what's the formula?

1 gallon equals .13368 cubic feet, so a tank that is 2x1x3.5 would be 52.3635 gallons
LxWxH /.13368
or the reverse 1 cubic foot = 7.4805 gallons
LxWXH X7.4805

231 cubic inches per gallon, so a tank 22"x18"x48" would be 82.285714 gallons

LxWxH /231
or the reverse
.004329 gallons = 1 cubic inch
LXWXH X.004329

Convert all of the tank measurements to feet. Then multiply all of the measurements together to obtain the volume of the tank in cubic feet.

Example: 2.5 x 1.1 x 1.5 = 4.125 cubic feet

Multiply this result by 7.4805 to obtain gallons
