1,000,000,000,000,000 = One Quintillion
1,000,000,000,000,000,000 = One Sextillion
1,000,000,000,000,000,000,000 = One Septillion

The Wiki FACTS! section (un-editable)
tells us there are 908,400 drops in one Gallon.

According to a Naval Meteorology & Oceanography Command
conversion worksheet for Junior and High School curriculums:
http://www.inventionfactory.com/lounge/scienceaction/gallons.htm
3.612 x 10^20 gallons of water in the Ocean
3,612,000,000,000,000,000,000
*328 million cubic miles* (Volume)
..........................................................................................................
According to an article at CNN/tech/science department,
they confirm the number of Gallons in the Ocean to be:

3.612 x 10^20
361.2 Quintillion gallons of water in the ocean
..........................................................................................................
This strengthens the reliability of their estimation of the Ocean's Volume:

According to "Physical Geography Fundamentals department:

*329 million cubic miles* (Volume)
==============================================
3.612 x 10^20 x 908,400 = 3.2811408 x 10^24
32.8 Septillion drops of water in the Ocean. 🙂
(or 32,800,000,000,000,000,000,000,000,000)
==============================================
According to the editors
of the Wall Street Journal Opinion Page,
based on an unscientific experiment to calculate the amount of drops in a Gallon,
they concluded it's roughly 22.2 Septillion drops of water in the ocean.
They calculated their number of drops in a Gallon,
with the factual estimated amount of Gallons in the Ocean,
based on the US Navy/Military,
which again, concludes the estimation to be at 3.612 x 10^20, g/w.
(or 361.2 Quintillion gallons of water)
http://www.opinionjournal.com/best/?id=110002460 (under Water Torture--II)
"According to the U.S. Navy,
there are actually 361.2 Quintillion gallons of ocean water."
==============================================
Editor's of the Wall Street Journal arrived at ... 22.2 Septillion.
Mr Master arrived at 32.8 Septillion.
To be fair considering the benefit of the doubt, I'll say roughly 25 Septillion. 👆
