whats the different between a mph and a knot?

Answer 1

A nautical mile is based on one second
of longitude (a second of latitude changes in footage
as you approach the N,S poles. Longitude stays the
same.) To convert knots to mph divide 6076 by 5280
times # of knots. To convert mph to knots divide 5280
by 6076 then times # of mph. Also, "knots" is a term
meaning nautical miles per hour.

In other words:
1 knot = 1.15077945 miles (6076/5280 = 1.15077945)

So for every knot you've travelled, multiply by 1.15077945 and you'll get the number of miles you travelled.

Answer 2

One mile per hour and one knot both relate to speed. A knot is one nautical mile per hour and is based on one minute of latitude or 6,076 feet. A statute mile is 5,280 feet.

Latitude is used to measure distance on a chart because all latitude lines are parallel to each other. One minute of latitude equals 6,076 feet anywhere between the equator and the pole.

Longitude lines, on the other hand, are not parallel to each other. One minute of longitude is equal to 6,076 feet at the equator and 0 feet at the poles (all longitude line intersect at the poles).

Answer 3

Thats simple - 1 knot = 1,151 mph

Answer 4

one knot is 1.15 mph rounded out to 2 decimal places.
one statute mile is 5280 ft and a nautical mile is 6076 ft

Answer 5

mph refers to statute miles.(5280 feet)
knots are nautical miles per hour.
Nautical miles are based on latitude. A minute of latitude is a nautical mile. (6076 feet)
A nautical mile is 1.15 statute miles
