Since the destroyer was the only surface fleet unit that could effectively locate, attack and destroy a submarine, it was logical that we should develop a destroyer type that would concentrate on the submarine and thereby release destroyers for fleet assignment. Hence, the destroyer escort. By July of 1943, the program was going full blast. No less than sixteen U.S. yards were involved in building DEs. Between February 1943 and the end of the war in September 1945, 563 DEs were built.
Convert kilometers per hour to miles per hour. You are currently converting speed units from kilometers per hour to miles per hour. 1 kph = 0.62137119223733 mph. kilometers per hour.
The wind speed must be in meters per second for the equation to be accurate. Convert mph to meters per second (m/s) by multiplying the speed in mph by 0.447. This value is obtained by dividing the number of meters in 1 mile, 1609, by the number of seconds in 1 hour, 3600.Example: 23 mph x 0.447 = 10.3 m/s.he amount of pressure exerted by wind on an object depends on the wind's speed and density, and the object's shape. If you know these three variables, you can easily convert wind speed to pressure in pounds per square inch (psi).
