About Inches per second squared
The inch per second squared (in/s²) equals exactly 0.0254 m/s², used in US customary engineering for machine tool acceleration, CNC linear stages, and vibration testing. Standard gravity is g₀ = 386.089 in/s², a constant embedded in US dynamics software (ANSYS, Nastran) configured with US customary units. High-performance linear motor stages reach 500-2000 in/s². 1 in/s² = 0.0254 m/s² ≈ 2.59 × 10⁻³ g₀.
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.
