Notes: 
U.S. survey feet may be converted to meters by multiplying U.S. survey feet by the fraction 1200/3937.

The common foot is a different unit of measurement, one-third of the Imperial standard yard, which is defined to be 0.9144 meters, exactly. Thus the (Imperial) foot is defined as 0.3048 meters, exactly.
