98 km per hour. can u believe this? why not refer ny good reference books or sites.
1 knot = 1 nautical mile/hour = 1.852 km/h exactly. This is based on the internationally agreed length of the nautical mile, as adopted by the US in 1954, the UK in 1970 and other countries. This is the definition used in most, if not all, modern circumstances. Knot is sometimes mistakenly used to refer to the nautical mile itself, but this is incorrect.
The speed of a vessel relative to the fluid itself, and not land, is referred to as 'boat speed' or, for aircraft, 'air speed' and is usually measured in knots. If the medium is flowing, this differs from the ground velocity by the velocity of the medium. 'Velocity made good' refers to ground velocity and may also be expressed in knots in navigation.
In some sailing ships, speed was measured by casting the chip log from the stern. The log was relatively immobile, and attached by line to a reel. Some sources suggest that knots placed at a distance of 47 feet 3 inches (14.4018 m) passed through a sailor's fingers, while another used a 28 second sandglass to time the operation. The knot count would be reported and used in the sailing master's dead reckoning and navigation. This method gives a value for the knot of 20.25 in/s, or 1851.66 m/h. The difference from the accepted value today is a bit less than 0.02%.

It really depends on the speed of the boat that the rope with the knot is tied to :-)

Faster than one mph and slower than two knots.

one knot = 6000 feet
one mile =5280 feet
6000 / 5280 = 1.364 MPH or 100 ft per sec.

just over 1 mile per hour
1 nautical mile is the same as a normal mile, exept it doesn't have the curve of the earth

One knot is equivalent to 1.15 miles per hour. (1.85 km/h)

about 1.150779 mph, just multiply, say 30 KTS=34.5 MPH, to go the other way just divide, hope this helps.
