3 knots equals 1.54 meters per second. Use the formula, worked example, and conversion table below to check the math.

3 kn = 1.54 m/s
kn × 0.514444 = m/s
Try: 2 kn to m/s 4 kn to m/s 8 kn to m/s
3 kn is also
3 kn = 3.45 mph 3 kn = 5.56 km/h 3 kn = 5.06 ft/s
kn
1.54 m/s

Step-by-Step Calculation

kn × 0.514444 = m/s
  1. Start with 3 kn
  2. Multiply by 0.514444: 3 × 0.514444 = 1.54
  3. Result: 3 kn = 1.54 m/s

This conversion factor (0.514444) is the same for every knot to meter per second calculation.
