Unit of fuel

[Daze]

1 Unit of fuel is 1 liter right?

[Holo]

Yes tencharlimit?

[Daze]

Thank you!

[Ydoow]

Probably no.

It honestly shouldn't really matter though. Just think of it as its own special type of unit.

The reason I assume no, is because weights/thrust/volumes are all adjusted purely to make the game enjoyable.

So, I assume, that if you took the volume, weight, and density of the fuel parts contain, I'd bet a lot of money those values wouldn't match up to anything in real life.

So that is to say, 1 Unit of Fuel is exactly that. 1 Unit. It's a general, ambiguous irrespective unit that holds no real value. It's just a unit.

You can still use it in math and everything, of course.

[Sir Nahme]

Yeah I have to second the determination of volume being irrelevant. Determination of mass for one unit of fuel is far more important

[Daze]

Mhm, but i wish to know how "much" it was that unit (for example compared to one Kerbal) just to see how much fuel i was wasting.

[Holo]

It is 1 liter, someone measured the fuel tank's volume.

EDIT: Also, in 0.17, LiquidFuel actually was measured in L, IIRC.

[Sir Nahme]

you'd still be better off determining that by mass, it's a better format because you can covert to energy density

[Daze]

So can i say that 1 unit can be compared at 1 bottle of water?

[Pedonymous]

Well it depends on if the bottle of water has a litre of volume or not.

It's definitely best to calculate mass rather than volume, because I don't care how much space it's taking up, I care how much it weighs.

Mass = Volume * Density

So with volume, you can work out mass

[comham]

Only if you know the density of the "liquid fuel" kerbals use. Which I guess we do, since we've got dry weight/full weight, and assuming fuel units are litres, yeah.

Squad ought to state the units used in the VAB tooltips. Like, put them in there, so it doesn't say "weight: 1.1" but "weight: 1.1 tonnes"

[HoY]

It can't possibly be in Liters. 1000 liters of liquid takes up exactly 1 cubic meter. 1x1x1. Our tanks would be a LOT smaller, or our volumes would be a lot higher if it were scaled in liters properly.

Edit: I don't actually care that its not scaled properly, I'm going to keep calling it liters because the system they decided to go with is metric. Keeps it simple by not mixing systems

Density is in the config files.

[Sir Nahme]

Note entirely true, we know the dry mass/full mass, not the weight

[Holo]

Note entirely true, we know the dry mass/full mass, not the weight

Mass * g = Weight

It's easy enough to calculate.

[Sir Nahme]

of course, but why would you calculate the weight when you already HAVE the mass to calculate energy density?
