It is not 1.2 mph, one knot equals 1.15 mph rounded out to 2 decimal places

It's one nautical mile per hour. A nautical mile is one minute of latitude. 60 NM is 1 degree of latitude. So the circumference of the earth is 21600 NM. This is super handy in navigation- when you measure on the charts that you need to go 5 degrees of latitude to the north, that's 300 NM. At 60 knots, you go 1 degree per hour.
The term comes from sailing ships, when speed was measured by tossing a float with a knotted line in the water, and timing a certain length of time and counting the knots- which were calibrated to speed.
A nautical mile is 6080 feet.

a knot is one nautical mile per hour.
As stated above, that's 1.2 miles per hour.
I don't know why it's different, but there you go.
