Hey guys,

after screaming at my screen for 5 minutes because my calculations didn't make any sens whatsoever I realized that the Isp in ksp is in [m] not in [m/s]. So I wanted to ask if there is a mod which automatically calculates the Isp in [m/s]. Because viva la metric system!!! xD

Thank you for your help in advance.

The ISP listed in Kerbal is in seconds, not meters (which isn't a measure of ISP at all) or meters / second.

To convert from ISP in seconds to meters / second (also known as effective exhaust velocity), simply multiply by Kerbin's acceleration due to gravity (9.8 m/s/s). I usually just multiply by 10 for even more simplicity.

This; which is why the rocket equation is: dV = (Isp * G) * LN(Mf/Me)
