I get the same as small. 26.7 (Typo, Sam?)

cubic inches x .00433 = US gallons

.

Water weighs 8.34 lbs /gallon. Weigh the tank empty, fill with water, weigh again, subtract empty weight then divide by 8.34 and that will give you gallons.

You also have to take into consideration that the area above the bottom of the fill spout is unusable.
Total Volume = 26.74 Gallons US
Filled Volume = 23.42 Gallons US

figure for cubic inches and divide by 231, your example is about 24.5 us gallons. the round ends would require more math than my brain can survive.

there's a little Buick in every US gallon, get it? 231ci.
