Where can I get the unit of the parameters?

[Frank_Black]

Hello everyone~ I wanna do some calculations about my rockets, but the problem is I am not sure what the unit of every parameters given by KSP is. For example, when it comes to rocket engine, there is always some parameters like 'Maximum Thrust: 200', but wait, what exactly the number '200' means? Is there someplace where I can find all these parameter units in this forum?

Thrust is usually in kN (kilo-Newtons) fuel units are in terms of mass, Isp is in seconds (IIRC) but really, if you use the rocket equation correctly units really don't matter since they will always work themselves out.

In game:

Part masses are in metric tons (megagrams or 1000 kilograms)

Thrusts are in kilonewtons

Isp is in seconds

Fuel/Oxidizer in 5 kilogram units

RCS fuel in 4 kilogram units

Some I'm not sure of:

Electrical charge

Xenon <- this is a mass, but not sure of the units

According to my experience, electrical charge units are completely arbitrary. Fortunately electricity has no mass.

Torque is probably in kN.m (not sure)

Xenon unit is 0.1 kg or 100 g.

A spotlight with "resourceAmount = 0.277" drains a battery holding 1000 "ElectricCharge", in one hour.

"resourceAmount" in the cfg of parts that produce or consume electricity is in units/second.

Assuming the unit of battery storage is Watt-hours, those units/second correspond to 1/3600 Watt. That can't be right, it's more like 1 unit/sec corresponds to 3600 Watt.

Following that, the Illuminator Mk1 draws 144Watt, Illuminator Mk2 draws 75Watt, the RTG produces 2.7kW, as does the OX-STAT Photovoltaic Panel (insanely OP).

OK, thank you all very much~
