Post by: Gordon Tarbell on July 08, 2007, 09:18:16 PM

What is the conversion from cubic inches to oz. of fuel?

Here is an online conversion calculator. Quick and easy to convert almost anything you have ever heard of and some that you have never heard of  to  almost anything you have ever heard of and some that you have never heard of. Do I make myself clear? LOL

Oh my gosh. I hope ''what ever works for you'' enters into this question. Bill Bischoff of navy carrier fame wrote an article in the NCS news letter (Dec. 1995) about fuel tanks for carrier and his formula was ''one fluid ounce equals 1.8 cubic inches'' so I've been figuring out the cubic inches of my tanks and then dividing by 1.8 and wala the ''capacity''. It seems to be working for me (for the last 13 years anyway). Geeezz, eric

The correct answer is .554 oz. If you look under the Download Area then Helpful Programs, Newest Programs, you will find Convert ZIP. This is a great little program that will convert about anything you want, and also allows you to do custom coversions.

Yes Eric;

   Whatever works for you comes into play here. Both figures are correct. Now about yours, LOL if you really want to come close the whole number is 1.8046875.   LL~ LL~ LL~  Just thought I'd lighten it up a "little" (sorry Billy Boy)

OK, all!

I generally have an idea how many fluid ounces I want for the particular tank, so I multiply that by the 1.804 to get the cubic inches needed.

If you know any two of the three terms (Length, Width, Height)  in tank volume, you can solve for the third one. Gets a bit more fun with unsual tank shapes... I usually build tanks with a rectangular front face, outer wall parallel or slightly outboard biased from the inner and a 90° wedge on the rear face.

Just another aspect of our hobby I enjoy... And it feels great when the pieces fit accurately, and the calculated volume checks out on the dot.

Fabricate your tank too long, fill it with the desired volume, cut it off there and solder on the end.  Foolproof.
