Subject: iterating methods on multiple parameters

I'm thinking there must be a great Ruby-way to do the same thing to many
different variables. Here is a boiled down version of what I have:

        @yn = Unit.new("#{@yn} feet")
        @yc = Unit.new("#{yc} feet")
        @v = Unit.new("#{@v} fps")
        @twmax = Unit.new("#{@twmax} lbs/ft^2")
        @tc = Unit.new("#{@tc} lbs/ft^2")
        @twc = Unit.new("#{@twc} lbs/ft^2")

My first thought is to create a hash of variables like this:

        results = {'yn' => "#{@yn} feet", 'yc' => "#{yc} feet", 'v' =>
"#{@v} fps", 'twmax' => "#{twmax} lbs/ft^2", 'tc' => "#{tc} lbs/ft^2",
'twc' => "#{twc} lbs/ft^2"}

then use a block something like this?

        results.each_value {|item| Unit.new(item)}

...but that doesn't seem to work. Any ideas to make this better?

Thank you!
