Best tank?

[American Patriot]

Does anyone know what the best tank for fuel:weight ratio is? I don't want to divide the values on the wiki myself(though I would already be done if I had just done that in the first place)

Welcome to the forum, @American Patriot, your question has been moved to gameplay questions.

Generally, tanks storing the liquid fuel/oxidizer combination used for rockets all have the same mass fraction. For example: all 1.25m FL-T tanks have a mass fraction of 9 (meaning 8 tons of fuel for every 1 ton of dry mass). The 1.875m FL-TX tanks also have a mass fraction of 9. As does the 2.5m Rockomax X series... and the 3.75m Kerbodyne S3 series... and even the 5m Kerbodyne S4 series.

If you look at different fuel types, then you start to see differences. For example, the three tanks in the FL-R monopropellant tank series all have different mass fractions (5, 7, and 8.5, resectively). The liquid fuel fuselages used in aircraft also do not always follow a consistent pattern.

To determine the mass fraction, simply divide the full weight of the tank by its empty weight.

streetwind said it right. you need not worry on which tank you use, they all have the same fuel:weight ratio
