So I'm given that the barometer reads 738.5 torr, and :delta: = 2.35 cm, SO, I know what an open-end barometer's pressure is P_gas = P_atm - :delta: h when P_gas < P_atm

What is the pressure in atms?

I do:

738.5 - 2.35 cm = 736.15 torrs x (1 atm /760 torr) which gives me .9686 atm

But the book says .9408 atm!

What am I doing (trivially) wrong?!

Not converting between cm and mm correctly. 
1torr = 1mmHg
1cm = 10mm

Now try again.
