Frequently asked questions
How many km/h is 1 kn?+
1 kn = 1.852 km/h. The table below lists the values you'll reach for most often.
How fast is a 100-knot wind?+
About 185km/h. Multiplying knots by roughly 1.85 gives km/h. In metres per second — how many meteorological services report it — 100 knots is about 51m/s.
How accurate are the results?+
The math uses internationally standardized definitions; only the display is rounded to significant digits. Accurate enough for school, work and daily life.

Unit guide
The formula
1 kn equals 1.852 km/h — multiply a kn value by 1.852 to get km/h. Example: 5 kn × 1.852 = 9.26 km/h.
Going the other way, 1 km/h = 0.539957 kn — multiply by 0.539957, or hit the swap button on the converter above.
When is this conversion needed?
Useful for speed-limit signs abroad, storm wind speeds (knots) and running or cycling pace math.
The knot
The unit of aviation, shipping and weather. One knot is one nautical mile per hour (about 1.852km), a distance derived from one minute of latitude. That heritage is why storm wind speeds and aircraft speeds are still reported in knots.
