[Solved] How to figure out true weight of a vehicle?

I am making a mod, and i want to make the prop have a very specific weight. It is too large to fit on the weight pad in the game. So, for example, if something had about 5,000 nodes, and the node weight in the jbeam file is set to 50, what would the weight be in pounds?
Another way of asking this could be what does one unit in jbeam node weight equal in real life?

 

The Game is from Germany so I would think it would be in Kilos

 

In my experience a value of 40 is about 800 pounds and 50 is more like 1000 pounds.

 

Thanks, i didn't know about that.
