Jet fuel references and the "Real world equivalent" section.

The statement claiming the terms "liquid fuel" and "jet fuel" are interchangable is inaccurate and unsubstantiated. "sometimes called jet fuel" and "Because jet engines use this fuel too, it is sometimes called jet fuel" are used to back up this claim. Sometimes by who? By you? Three of your friends? This is weasel word use. Jet fuel can be a type of liquid fuel but regardless of how many people incorrectly use jet fuel in place of liquid fuel it's inaccurate and should be removed.

In the Real world equivalent section there's more weasel word use: "some compare liquid fuel to RP-1", it needs to go. RP-1 is also referenced in the same manner jet fuel was above in that it's comparable to liquid fuel. Both jet fuel and RP-1 can be types of liquid fuel, you keep referrening to them as an alternative to liquid fuel which is inaccurate.

As there is no mention of either jet fuel or RP-1 in KSP there's really no reason for these terms to appear in the article at all other than external reference links for further reading. I'll delay further editing so xZise or someone else can make a legitimate case for these statments to remain rather than provoke an edit war because the rest of what he changed/added was beneficial to the article and he should be allow to present a case. — Preceding unsigned comment added by ‎SamBanford (talk • contribs) 11:03, 11 March 2014‎ (UTC)

Hi, unfortunately I can't provide any references both claims without doing further research. But at least some indicators why I added both back in. There existed an jet fuel article, which I changed into an redirect to liquid fuel, as there is no dedicated jet fuel resource (yet). There is actually indication of jet fuel in Mk1 Fuselage - Jet Fuel.

And the RealFuels mod previously added some fuel types (with it kerosene) but some engines still wanted LF. He then said, that he wants to replace LF with kerosene (okay granted this might not be exactly RP-1, but afaik this is the most common kerosene used in rockets (at least in the US)). ([1] and [2]) Of course he is not an official spokesperson, but maybe that's why I think LF is RP-1. The previous version of RF, Modular Fuel System, also treated LF as RP-1 ([3]). — xZise [talk] 07:09, 11 March 2014 (CDT)

Unit of measurement

Changing liters to units because densities are inaccurate to volume of containers. PDS314 (talk) 14:27, 11 December 2013 (CST)

Nevermind, I was unable to edit this. Someone with more experience, please edit everything on the wiki to give accurate densities of fuel as per unit not per liter or per meter cubed. For example, all Rockomaxx or FL-T tanks store slightly over 800 kg of fuel per meter cubed, not 5000 kg as various pages on this wiki mention. The other types of tanks (ROUND-8 Toroidal, Oscar-B, all jet tanks) store at even lower densities. As proof, consider that the external volume of an X-64 Orange tank is slightly over 39,000 liters and the tank stores 32 tonnes of fuel. PDS314 (talk) 14:37, 11 December 2013 (CST)

As noted in the infobox (when you hover over the liter unit) it asumes that 1 liter == 1 unit. As ingame the unit liter never appears we can be sure in what unit they measure it. It can also be that 1 liter isn't defined as 1 dm³ in the KSP universe. Instead of applying some conversion, I would suggest dropping the unit and simply use the ingame unit like with xenon gas.

Using another value might irritate others. So when ingame a tank has a “capacity” of 1000 but here in the wiki it shows as 500 l (I don't know the conversion factor so this is only an example) others might wonder which value is correct. Also all formulas need to be updated that 1 l ≠ 1 unit and that the formulas work with units instead of liters. — xZise [talk] 16:10, 11 December 2013 (CST)
