These units are not compatible

Hello everyone,

I hope you are doing fine!

I recently calculated concrete bending stiffness using Mathcad Prime 8.0.0.0.

However, when I was writing an equation, I got the message "These units are not compatible" in the Composite Bending Moment Equation.

Can someone please help?
I attached the full calculation below.

Thank you in advance!

It looks to me that the problem is in sigma.conc where you should add the unit Pa.

As an alternative you may use "Zero" instead to let Prime chose the appropriate unit, Note the capital "Z", its mandatory.

Personally I would prefer the first fix, adding the correct unit explicitly.

N_conc returns 1/m², whereas it should be N.

You might find it helpful to use a try-else programming operator to catch errors and return values that might be of interest.
