These units are not compatible

[BB_14100646]

I'm using MathCAD 9.0.0.0. For whatever reason, MathCAD is having a problem with variable units of my final equation in my attached file.

When Prime moans about incompatible units its usually correct. Unit checking is one of the strengths of the program.

In your case "B_cg" is a length/distance, but "w_L" is a weight. You sure can't add quantities of different dimensions.

Maybe you meant a product instead of the sum?

Or more likely you wanted to use "w_b" instead of "B_cg" !?

Yes, you are correct with the wb. Thank you! I have another one with the same error, but different problem. I'll start a new post.
