Using SolveSys to solve equation with variable using unit
Sorry if it's a duplicate or already solved but I don't find ...
how can I use solvesys (on hp prime) to solve system with variable using units: i.e.: distance=time*velocity distance in nmi, time in hour and velocity in knot I know I can remove unit and it's done. but if the velocity is in m/s, I must convert it before or adding a factor in equation. I come from hp48 and on this one it's easy. Can you help me ?

RE: Using SolveSys to solve equation with variable using unit
I’m not sure if this is what you’re looking for, but you can solve in CAS:
solve(10_nmi=5_h*x,x) Returns [2_nmi/h] You can use USIMPLIFY if you get a mix of units like m*s/s > m, and MKSA to go from nmi/h to meterkilogramsecondampere system.
