Subject   st: Getting rid of units in string variable

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,

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,
