I need a comprehensive way to calculate Delta-V

[mobkillertman]

I love KSP but I have looked up delta v equations (specifically delta v is equal to Isp times the Log of M1/ M2) and i try doing it but it comes up with some weird number, I just need to know what my ships can do.

For the delta-V equation, the ISP listed in the game should multiplied by ~9.8. Also I would recommend Kerbal Engineer Redux, it's a great mod that calculates delta-V, Thrust-Weight ratio, and some other useful information.

I'll second KER. It actually gives more detailed information than MechJeb does, without the temptation to use the autopilot. On the other hand, MechJeb does provide most of the information, so if you want an autopilot (or a fly by wire system, for that matter), it will provide the important information.
