Converting hash values from fahrenheit to celsius.

cheako has asked for the wisdom of the Perl Monks concerning the following question:

What's your fav read/write iterator for a hash's values?

Temperature:
foreach (keys %temp) { $temp{$_}-=32; $temp{$_}*=5/9; }

Percent:
foreach (keys %ratio) { $ratio{$_}*=100; }

My favorite would be `$_-=32, $_*=5/9 for values %temp;` [download]	[reply] [d/l]

If you don't care about the keys, why not use values instead?	[reply]
