Hi, I am looking for a way to handle units in Sagemath, both numerically and symbolically. I am trying to see how I can emulate the Mathcad capability of unit consistency in Sagemath. For example, How would I be able to do the following: Symbolic: delta= PL/AE , P=3F N, F=deltaAE/3*L N

numerical: 1kN +500N = 1.5kN

Thanks for the help

This may enlighten you

I found this facility a bit awkward (at least initially) but useful. LaTeX output may use a bit of love...

@Emmanuel Charpentier I have seen that documentation. Though, it functions like a symbolic variable. You can't change m to mm and vice versa easily.

Huh ?

m=units.length.meter
mm=units.length.millimeter
sage.symbolic.units.convert(2/10*m, mm)
200*millimeter

Also :

(200*mm).subs(mm==1/1000*m)
1/5*meter

@Emmanuel Charpentier Does this work the same way if I want to change the unit of the same variable ? for example; L =10m to L=10000mm ?
