You made a mistake common to those that don't understand diiving physics... depth (for diving applications) is a unit of pressure NOT length.. you used a length conversion..
Hmmmm... I believe what you intended to say was something like this:
Depth is a measure of distance (see your dictionary, mine were Funk & Wagnalls and a Webster) but divers actually use SPG's which measure pressure and convert it to an equivalent depth measurement.
By the way, I was disappointed to find that my computer is set to assume I'm diving in fresh water, thus it over-estimates depth when I dive in salt water. I guess I've really been to 200 ft... just close.
