which shows inches to gallons for a 290 gallon oil tank. I have tried every combination I could think of in my search, but can not come up with anything. I have found a 275 gallon tank and a 300 gallon tank. As far as I know, the 290 gallon tank is 33" in diameter and is round.

Wouldn't it be 8.8 gallons/Inch?

290gal / 33" = 8.78 gals/in

I guess it that would be if the tank was square.

Compare that calculation to the ones you've gotten for the 275 and 300 gal tanks. How do they compare? I'm guessing it's probably not off by much

No, the first inch is a lot less than the center inch of the tank

I'm assuming your tank is a cylinder and standing on end
Diameter = 33" = 2.75ft
In order for your tank to have a volume of 290 gallons, it would have to be approx. 6.5ft long.

So...

V = Pi * 1.375ft^2 * 6.5ft = 38.58766 ft^3

There are 7.481 gallons in one ft^3

Multiply V * 7.481 gallons/1 ft^3 = approx. 289 gallons

so now...go back to the original formula and substitute 1 inch (.083 ft) for H and run the conversion. You should get 3.69 gals/in

This assumes the ends of your tank are flat and not buldged out.

Most cylindrical tanks of this type are mounted on their sides.
