How to Convert Knot Per Second to Meter Per Second Squared

1 knot per second = 0.514444 meters per second squared

Meter Per Second Squared = Knot Per Second × 0.514444

Example: 640 kn/s × 0.514444 = 329.24 m/s²

Reverse Conversion

To convert meters per second squared back to knots per second:

  • Remember, 1 meter per second squared equals 1.94384 knots per second.
  • To convert 329.24 m/s² to kn/s, multiply 329.24 x 1.94384, resulting in 640 kn/s.

640 kn/s is also equal to:

  • 1080.2 foot per second squared
  • 33.574 standard gravity
  • 32924 gal
