How to use
- Enter a value in the Meters Per Second field.
- The Knots figure appears immediately — no button to press.
- Typing in the Knots field converts back to Meters Per Second the same way.
- Use the reference table for the values that come up most often.
Meters Per Second to Knots formula
Converting meters per second to knots is a single multiplication by 1.94384449.
kn = m/s × 1.94384449
Put another way, one meter per second is exactly 900/463 knots.
Why this factor: the meter per second and the knot are both defined against the meter per second, so dividing one definition by the other gives 1.94384449 directly. Both definitions are set out in full below.
To go the other way, divide by 1.94384449 — or use the Knots to Meters Per Second converter, which is the same calculation reversed.
Worked example
Start with 30 m/s. Multiply by 1.94384449 to get 58.315335 kn.
30 m/s × 1.94384449 = 58.315335 kn
The converter above does this for any value you type, in either direction.
What is a meter per second?
Meters per second is the SI unit of speed, and the one physics equations expect.
Definition: Derived directly from the meter and the second.
Where it is used: Physics and engineering calculations, wind speed in meteorology, and sound and projectile velocities.
What is a knot?
A knot is one nautical mile per hour, the speed unit of ships and aircraft.
Definition: Exactly 1,852 meters per 3,600 seconds, so about 0.514444 m/s.
Where it is used: Marine and aviation speeds, and wind speed in forecasts for sailors and pilots.
Worth knowing: Say 'knots', never 'knots per hour' — the 'per hour' is already inside the unit.
Meters Per Second vs Knots
The meter per second is an SI unit while the knot is a specialized unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
Frequently asked questions
How many knots are in a meter per second?
One meter per second equals 1.94384449 knots.
What is the formula to convert meters per second to knots?
Multiply the number of meters per second by 1.94384449. To reverse it, divide by 1.94384449 instead.
How do I convert knots back to meters per second?
Divide by 1.94384449, which is the same as multiplying by 0.514444444.
How many knots are in 10 meters per second?
10 m/s works out to 19.438445 kn.
Is there anything to watch out for with knots?
Say 'knots', never 'knots per hour' — the 'per hour' is already inside the unit.
How is the meter per second defined?
Derived directly from the meter and the second.
