Convert Knots per second to Standard gravity
Convert Knots per second (kn/s) to Standard gravity (g₀) instantly and accurately.
Conversion Formula
g₀ = kn/s × 0.05245873407
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 Standard gravity
Standard gravity (g₀) is defined as exactly 9.80665 m/s² by the 3rd CGPM (1901), chosen to approximate surface gravity at ~45.5° latitude. It is the universal reference for human g-tolerance: fighter pilots sustain up to +9 g₀ with G-suit; sustained +3 g₀ causes greyout unprotected; F1 drivers experience +5 g₀ lateral and -4 g₀ braking. Pound-force is defined as 0.45359237 kg × g₀ = 4.44822 N (exact). Rocket specific impulse in seconds = thrust / (mass flow × g₀). 1 g₀ = 9.80665 m/s² = 980.665 Gal ≈ 32.174 ft/s² ≈ 35.304 km/h/s.
