I really hope your default is in lbs

I'm a big fan of using units. There wasn't really anything (update: unit-self-aware) on CPAN at the time, so I wrote Math::Units::PhysicalValue, which would make the initial weight so much clearer. 

use Math::Units::PhysicalValue qw(PV);

my $weight = PV "170 lb";
my $mass   = $weight + "0 kg";

print "My mass on earth at sea level is $mass.\n";

    I feel obligated to point out here that your mass is not dependent on your position. :-) (Oddly enough, though, nobody seems to want to figure their weight in Newtons.)
