believe it's 6 feet per.

confirmed:

http://www.ilpi.com/msdS/ref/distanceunits.html

has a fair table

also, typing something such as "4 fathoms in feet", " fathom in feet", or "10mm in inches" into google will convert it

Smile it is

I just looked in my wonderful new sailing book called Sailing Fundamentals( hope I spelled that right!), and a fathom is 6 ft.

Might also be interested in knowing that a cable is 720 feet or 120 fathoms

FWIW, a related bit of information is that charts which show depths in fathoms will express them as, for example, 6-1 (with a smaller figure 1 than the figure 6) which is interpreted as fathoms plus feet, or a depth of 37 feet.

And, of course you will find charts showing depths in meters which you can 'roughly' convert by multiplying by 3.

Most depth guages allow you to select the displayed units so you can synchronize the display with the chart but I find that a bit confusing so usually do the math in the head. With approaching age I may have to change the display :-)

Valhalla:

Since a meter is a tad over three feet (39.3") I'd say you better use a factor of 2 rather than 3 for converting to fathoms, or you may get a nasty surprise one day.

OOPs - sorry - guess you were converting to feet........

I always thought it was a tenth of a nautical mile, or 600 feet. So Googled it, and saw both 600 and 720 mentioned. Most of the blue-water merchant captains I've talked to said they use 1/10 mile, 10 cables in a mile. Maybe the "common" measurement has overtaken the "correct" one.

A cable is 1/10 of a nautical mile. A fathom is 1/1000 of a nautical mile. A nautical mile is 1 second of latitude (1/60 of a degree)
I think.
