Subject: build hash by iterating

I am building a hash this way:

h = {}
i = 0
j = 24

while i < 15 do
  h[i] = j
  i += 1
  j += 6
end

=> {5=>54, 11=>90, 0=>24, 6=>60, 12=>96, 1=>30, 7=>66, 13=>102, 2=>36,
8=>72, 14=>108, 3=>42, 9=>78, 4=>48, 10=>84}

Just what I need, but doesn't seem very Ruby-friendly

And if I want to change each hash value from fixnum to string, how would
that be done?

this is not working:  new_hash = h.each_key {|k| h[k].to_s}

thank you!
