Ok all you smart guys tell me how many gal this tank will hold it is
65" long 23" wide and 21" tall if I am right in my math I get 130 gal by volume and 139 by size. Please advise.

Thanks

I use this online calculator for figuring tank capacity:
http://www.calculatorsoup.com/calculators/construction/tank.php (http://www.calculatorsoup.com/calculators/construction/tank.php)

135.91 gallons.  That assumes measurements are of the inside dimensions of the tank.  130 gallons is probably closer to its actual capacity if you measured the outside dimensions.

Edit: I have nothing better to do... strep throat has me stuck here at my computer for a couple days.

LWH = V
231cu.in. = 1gallon

(65in)(23in)(21in) = 31395cu.in.
31395cu.in. = 135.91 gallons

Should be 135.9 gallons.

A cubic foot of water is roughly 7.5 gallons.

So (65x23x21)/12^3=18.17 x 7.5 = ~135.9 gallons.

So guess I can call it close enough. It is the fuel tank in my mci8 the plate on it says it is 144 us gal but it look like
the PO cut so he could but the gen. in behind it. It had a 150 gal tank in beside it that I took out and am going to get ride of.
Don't need to carry that much fuel.

For easy reference in the future, the BCM tank capacity calculator:

So your aforementioned size equals about 135.90909090 US Gallons, or thereabouts.  Then you must divide by a factor to determine net capacity and then again to determine actual draw capacity then again to determine available capacity and then again to get practical capacity.  Are we having fun yet?  Do not also forget to include the interior baffles if you have them.  That will remove a little also also.  So on and so on.   HB of CJ (old coot) :) :) :)

Oh ... there is more I forgot kinda.  These are inside sizes and does reflect outside sizes as the wall thickness can vary.  Wow!  Also the contents temperature makes a difference.  A gross example would be the water completely freezing up solid, which would expand the water resulting in either a over full tank or a tank holding slightly less.  Then we have ....

be certain not to put the 135.90909090 US Gallons in during cold temps wwith out burning a few off before the temperature rises 30-40 degrees  :o

Pretty obvious most of us don't have enough to do today or we're just avoiding what we should do.
