Rocket Engines give you their max output in kN with this you can calculate what they can reasonably carry into orbit depending on the planet or moon you are on. Force = Mass * Acceleration. Acceleration is equal to the planet's gravity, Mass is given in kg per part of the rocket, and Force is kN. If your thrust force listed below is less than the weight of the rocket in kN then you will not even take off. It is better to have a thrust much higher than the weight of the rocket or else you risk running out of fuel on launch and on landing.

Name Base Power Usage Rocket Mass Contribution Max Thrust Efficiency Exhaust Velocity
Pressure Fed Liquid Engine 20W 500kg 29,2kN 160% 6,18km/s (Isp: 631s)
Pressure Fed Gas Engine 10W 500kg 40,3kN 96% 3,86km/s (Isp: 394s)
Pumped Gas Engine 200W 500kg 16,2kN 100% 4,02km/s (Isp: 411s)
Pumped Liquid Engine 200W 500kg 17,6kN 140% 5,47km/s (Isp: 559s)
