Warning about units in Simulink

I am rotating a vector containing forces using a quaternion, and I can't find a way to make Simulink understand that the result units are in newtons.

I added a block "signal specification" but it doesn't solve the problem.

Hi Jesse Beaupre,

I understand that you want to get the output of the Simulink model In Newton.

For the conversion of the unit, you can use the ‘Force Conversion Block’ present in the ‘Aerospace Block set’, or you can enable the Automatic unit conversion command if its disabled.

For better understanding, kindly go through the following links:
