#"1 mile"# #-=# #1.609*km# #=# #1.609xx10^5*cm#

Explanation:

#"1 mile"# #-=# #1.609*km# #=# #1.609xx10^3*m#

#=# #1.609xx10^3*cancelmxx10^2*cm*cancel(m^-1)# (because #1*m-=100*cm#).

#=# #1.609xx10^5*cm#

And thus, #345*cm# #=# #(345*cancel(cm))/(1.609xx10^5*cancel(cm)*"mile"^-1)# #=# #??"mile"#

Is there any move in the States to adopt the metric system?
