Putting text at the end of formula results

I'm trying to enter relatively simple drug calculation formulas in Excel where the result is appended with the proper units to administer. For example, if I'm calculating for units of regular insulin with a formula such as:

=0.75*f2

I'd like the cell to make the above calculation, and append it with "Units Reg Insulin" or something similar. Thus far, I've just been putting the units as text in adjacent cells but the result looks a bit messy.

Is this possible? I'm using Excel 2007 and the Help index does not seem to offer much guidance about this.

Thank you for any help!
