UnitConKnots to KM/H Converter
Convert knots to kilometers per hour for marine and aviation contexts where metric speed units are preferred. This conversion is common in meteorology and international shipping.
Formula
Multiply knots by 1.852 to get km/h. To reverse, divide km/h by 1.852 to get knots.

About these units
Knot
The knot is defined as one nautical mile per hour. Since the international nautical mile was fixed at exactly 1852 meters in 1929, one knot equals exactly 1.852 km/h — making this a perfectly exact conversion.
Kilometer per Hour
The kilometer per hour is the metric unit for speed, used by road signs and vehicle instruments in most countries. In meteorology, it is used alongside knots for wind speed in different reporting contexts.
Frequently asked questions
30 × 1.852 = 55.56 km/h.
Exactly 1.852 km/h, since the nautical mile is defined as 1852 m.
64 × 1.852 = 118.5 km/h — a Category 1 hurricane threshold is approximately 119 km/h (64 knots).
