How Does Changing MPa m^0.5 to MPa m^-0.5 Affect Calculations?

[PetePetePete]

I know the units of measurement for this are: MPa m^0.5

However a question I am working on has it as MPa m^-0.5

What is the difference and does it affect the way I calculate the answer?

Would appreciate your insight.

Thanks
Pete

The difference between MPa m^0.5 and MPa m^-0.5 is that the sign has been changed from positive to negative. This means that the value of the unit of measure is inverted. Therefore, it will affect the way you calculate the answer, as you will need to invert the value when you use it in your calculations.
