Nonsensical question. 'Knot' is a measure of speed or velocity and kilometre of distance or length. The two are not compatible. You might as well ask how many ounces are in a kilowatt.
To cover 41 kilometres/hour you would be sailing (presumably) at 22.14knots or 22.13 UK knots.
Originally the knots that gave their name to the unit were placed at intervals of 47ft 3in along a rope. I suppose - in a round about way - you could say that there would therefore be 341.62 knots in your 41km but I suspect that isn't the answer you were looking for...
"41 knots" means 41 nautical miles per hour. In terms of a few other more familiar units: -- 75.9 kilometers per hour -- 69.2 feet per second -- 47.18 miles per hour
41 Knots is 47.19 miles per hour.
55 knots = 101.86 kph
Its 25.928kmph.
18.5
That would be 41 kilometers
879.7 kilometers per hour.
Answer: 41 mi. = 65.9831 km
30 Knots = 55.56 Kilometers per Hour
48 Km/hour
Approximately 621 statute miles per hour or about 1,005 kilometers per hour.
55 knots is 101.86km/h
