Re: Solve equation with variables of different units

sir, as per this thread, can you help me with this equation, the unit of result according to my design code should be as Mpa (N/mm2).

Its always better to open a new thread for a question.

 

You are talking the square root of an value with unit MPa, so you cannot expect the result to have the unit MPa, too.
Rather it has to have to unit root of MPa, whatever that may be:

The formula you are using presumably is an empiric formula which is not unit consistent.
So one way to deal with is to divide the the values by its expected units and add the desired unit of the result at the end:
