Trouble calculating delta-v


Recommended Posts

Since I used MechJeb as a reference for the delta-v calculation I think it isn't on Sqaud's side to fix this, rather than on whoever-made-MJ's side.

The problem is KSP uses 9.82 as the constant. It should be 9.81 - which has nothing to do with gravity. It's purely for converting between force units and mass units. MechJeb just uses the value that works with KSP.

That was what bugs me in the first place.

MechJeb and KER both use 9.82, because that's what KSP uses to calculate mass flow rates from thrust and Isp. If they used 9.81 it would be true to real life but not accurate for KSP. If KSP changed to use 9.81 the mods would quickly follow.

Thanks Crown, this is very helpful! :)

You're welcome.

I didn't know that. Well, then ... Squad, fix your game :D

No, really. Since we know that now I'm fine for now. It's an inconvenient thing but I'll get used to it, changing that would be nice but is not of high priority (for me at least).
