Velocity unit after NBodySimulation calculation?

Hello!
I created a simulation of the Solar System by using NBodySimulation and now I would like to see velocity of Planets at a specific time (tend) But I have a problem with the units. As you can see in the picture, there is 1/kg unit. This changes during NBodySimulation, because before calculating the velocity unit is correct.

Please post a simple example. It’s hard to answer that question in the abstract. Also be sure to use the code button in the upper left corner so the code can be copied and pasted.

Regards

I added the attachment. Maybe it will be easier
