1 Knot is 1 nautical mile per hour.
One mile is 5280 ft, whereas a nautical mile is 6076 ft.
To convert Kts to mph, multiply by 1.15.

There are a couple of issues to clarify here. You ask about "Miles" and "Knots". In dealing with marine navigation, unless otherwise specified, when the term "miles" is used, it is presumed to mean "Nautical Miles" and the conversion factor from Statute Miles to Nuatical Miles is 1.15 . A nautical mile is equivalent to the length of one minute of arc of Latitude at the Equator and is also the distance that the Ground Position (GP) of the sun travels in 4 seconds.
Knots are the measure of speed. The term comes from naval history. Knots were tied in a line at a predetermined spacing. This line was then payed out from the boat while under way and the number of knots that passed through the fingers during a specific time frame were recorded. Hence if 6 knots were felt during that time frame, the boat was moving fast enough to cover 6 nautical miles in an hour.

A Knot is one nautical mile per hour. It is easier to calculate a nautical mile in terms of yards than feet. It is close enough to figure a nautical mile at 2,000 yards. A land mile is 1760 yards. And yes, Jack H. is right.

A knot is one nautical mile per hour. A nautical mile is a unit of distance used in navigation, an internationally agreed standard (since 1959) equalling the average length of one minute of arc on a great circle of the Earth, or 1,852 m/6,076 ft.
In other words, I knot is 1.15 mph, so 10 knots is 11.5mph, 20 knots is 23mph and so on.

A knot is 1 nautical mile per hour or 1degree of latitude, so its the time it takes for a vessel to travel one degree of latitude

1 international knot = 1 nautical mile per hour = 1.852 kilometres per hour exactly.
This is based on the internationally agreed length of the nautical mile. The international definition was adopted by the US in 1954 (which previously used the US nautical mile of 1853.248 m)[2]. The international definition was adopted by the UK in 1970 which previously used the UK or Admiralty nautical mile of 1853.184 m. This is the definition used in most, if not all, modern circumstances. A common error that should be avoided is to use the term 'knot' to refer to the nautical mile itself.

distance on all navagation charts are in knots and a knot was devised by tying nots on a rope at equal distance and paying the rope into for a given period and that is where knots came from Donadea

Daniel is right. I will add it is used by vessels, sea and air.
Also Zulu time is used. Sea and air communication times are always made in Zulu time which is a world wide time reference. Zulu is the name for Meridian Time Zone which is zero. So if I say 1400 zulu, then it would be 0700 where I am now.
