Unexplained behaviour when using .prefix("") #253
Description
Hello,
I am trying to force a variable 'l' into units of m by using .prefix("unity").
In the first image, you can see the calculation of F_st,90 carried out using the 'unprefixed' value of 'l' which is in units of mm. F_st,90 has final units of N as expected.
In the second image, the calculation is carried out with the 'prefixed' value of 'l' which is in units of m. However, F_st,90 now has final units of Pa for some reason. This then causes an error in the rest of the code since the units are not N as required.
Does anybody have any idea why this issue occurs and if there is any way I can avoid it?
