Hi,

I am in the process of converting string variables to numeric (e.g. weight values), but many have the units entered with the numeric value...

For example,
 101.36kg      
      101.5          
      101.7     
     102.51           
       102kg

Is there an easier way to get rid of the "kg??" 
Than to have to do:
replace  var = "101.36" if var == "101.36kg" (for every entry with units attached)

Thanks so much,
Rebecca
