Conversion Formula

mGal = kn/s × 51444.44444

About Knots per second

The knot per second (kn/s) equals 1852/3600 m/s² ≈ 0.5144 m/s², used in aviation and maritime operations where speed is measured in knots. Aircraft carrier catapult launches accelerate an F/A-18 from 0 to ~150 kn in 2-2.5 s, giving 60-75 kn/s ≈ 31-39 m/s². A commercial jet rejected takeoff from V1 (~145 kn) to rest in ≈25 s decelerates at 5-6 kn/s ≈ 2.6-3.1 m/s². 1 kn/s = 463/900 m/s² ≈ 5.25 × 10⁻² g₀.

About Milligal

The milligal (mGal) equals 10⁻⁵ m/s², the standard unit for geophysical gravity surveys. Bouguer gravity anomalies - reported in mGal after latitude and terrain corrections - reveal subsurface density contrasts: salt domes give +5 to +50 mGal, oceanic spreading ridges -200 to -300 mGal. Standard gravity is ≈ 980 765 mGal at sea level. The International Gravity Reference Frame 2016 is tied to absolute stations accurate to 0.01 mGal. 1 mGal = 10⁻⁵ m/s² ≈ 1.02 × 10⁻⁶ g₀.
