How to Convert Meter Per Second to Knot

1 meter per second = 1.94384 knots

Knot = Meter Per Second × 1.94384

Example: 345 m/s × 1.94384 = 670.63 kn

Reverse Conversion

To convert knots back to meters per second:

  • Remember, 1 knot equals 0.514444 meters per second.
  • To convert 670.63 kn to m/s, multiply 670.63 x 0.514444, resulting in 345 m/s.

345 m/s is also equal to:

  • 1242 kilometer per hour
  • 771.74 mile per hour
  • 1131.9 foot per second
