I get 98.7 US gallons for the outside dimensions you gave. Close enough.

Just bought a used aquarium which measures 19" x 20" x 60". The seller said
it was Oceanic Brand and held 100 gallons. My calculations came up with
less than 100 gallons, though math is not my strong point. Oceanic no
longer makes that size. Any opinions?

Yes, that's close enough for me too. Thanks.

A US gallon is 231 ci.

19x20x60=22800 ci = 98.7 US gallons.

Now, assuming your glass is 1/2"

18.5x19x59=20738.5 = 89.77 US gallons inside.

But tanks are sold by the outside dimensions.

Let's see (using round numbers):
19"x20"x60" = 47cm x 50cm x 150cm = 352500 cm^3 = 356 l = 93gal

That's what I came up with, comparing it to my 45 gallon tank.

I guess I'll just measure the water while I put it in during initial setup.

If you want to know how much water fits in the tank, then that is the only
way anyway, because you are loosing quite a bit of space for gravel,
decoration, machinery, empty space on top of tank, etc. While the water
volume can be very valuable for e.g. medication, it is a different number
than the nominal size of a tank.

Therefore I prefer the European custom where tank size is specified in
outside dimensions (e.g 50x50x100) instead of by volume such that you cannot
confuse nominal size and water content.
