You've given us units but we'll never be satisfied.

Most of the know universe uses SI units for dimensioning and calculations. But in the United States we still us US or Imperial units i.e. feet, inch, lbf(force), lb(mass), kip. SMath seem to do it calculation in SI units and that's what's output.

When you have the time can you implement an option to select a consistent set of the units for output.

Sure, this will be implemented later.
