How many mph are in a knot?
One knot is approximately 1.15078 mph (exact: 1 knot = 1.852 km/h and 1 mph = 1.609344 km/h).
Detailed answer
A knot is one nautical mile per hour. The international nautical mile is 1,852 m, so 1 kn = 1,852 m/h. Divide by the meters per mile (1,609.344 m/mi) to express the same speed in mph.
Relationship context
Marine and aviation navigation traditionally use knots; comparing to road mph needs this factor.
