Re: making a shorter code!

[tlhf]

#!/usr/bin/perl -l
print"Enter the distance to be converted:";
printf"$_ kilometers= %f miles\n$_ miles= %f kilometers",($_=<>)*0.621
+4,$_*1.609;

Is the shortest I could think of in a short period of time. At 144 bytes. The chomp seemed unecessary (Perl 5.6.1/Win32), and -l allowed me to skip \ns, and using printf allowed the three chars of %f and a commer, rather than "..". I didn't seem to get much benefit by using $m=miles or $m=' miles' tho.
