in reply to Calculate Your Weight On Various Heavenly Bodies

I really hope your default is in lbs...but 

if ($default->is_KG()){
   require Rope;
   my $exerc = Rope->new(weight=>'+5');
   $exerc->skipping until $default < 100;
}

    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.)

    Yes, that default is definitely pounds, not stone, kilograms, ounces (avoirdupois or otherwise), or anything else. It's still too high of a default, though.
