   You're on a roll.  First the verb/vowel thing, and now the atm/feet of
water thing.

(1 atm = approx. 32' water) 

  At sea level = 1 atmosphere

At 32' underwater = 2 atmospheres

If you descend from a depth of 32' to 64' how many atmospheres has the pressure increased?
And so... how many atmospheres is 32' of water equal to?
