Convert Meters per Second to Knots
Meters per second to knots is the conversion you need when a speed is measured in the metric, scientific way but you're working with sailing, aviation, or weather data that speaks in knots. One meter per second is about 1.943844 knots, so the number gets a fair bit bigger when you switch from m/s to knots.

The formula
To convert meters per second to knots, multiply the speed in meters per second by 1.943844:
knots = meters per second × 1.943844
A worked example
Say a weather station clocks a wind gust at 10 meters per second:
10 × 1.943844 = 19.44 knots
That's a brisk, noticeable wind — strong enough to be called a "near gale" on the scale sailors use.
Why it's an approximation
A knot is defined from the nautical mile, a unit tied to a minute of latitude, while the meter comes from the metric system. Those two definitions don't line up evenly, so working out the exact relationship produces a long decimal that never terminates in a clean, short number. That's why the factor 1.943844 is rounded, and why the displayed result is always an approximation rather than a perfectly exact figure.
When you'll use it
Converting scientific or metric wind and speed readings into the knots used in sailing, aviation, and marine weather forecasts, and comparing lab or model speed data to nautical charts and flight instruments.
Frequently asked questions
How many knots are in a meter per second?
About 1.943844 knots. The value is a rounded approximation, not an exact figure, because it comes from converting between two systems built on different definitions of distance.
Is the meters-per-second to knots conversion exact?
No. The factor 1.943844 is a rounded decimal — a knot is defined from the nautical mile, which does not divide evenly against the meter, so the true relationship is a long, non-terminating number that gets rounded for practical use.
What's a quick way to estimate m/s to knots in my head?
Multiply by roughly 2. A 10 m/s wind gust is about 19 to 20 knots. For anything that matters, use the exact factor above.
