As someone who uses parameters on a daily basis, it would be awsome to use unit-combinations. When calculating part dimensions depending on loads, the calculation of torque in Joule is unconvenient. The given units are great, but i miss some basic units made up of already given units like: [m/s^2] for general acceleration or just to define gravity [N*m] as torque input [mm^4] aerial moment of inertia or other combinations.
