Convert Inches per Second to Metres per Second
Convert Inches per Second (in/s) to Metres per Second (m/s) instantly and accurately.
Conversion Formula
m/s = in/s × 0.0254
About Inches per Second
An inch per second (in/s) = exactly 0.0254 m/s = 25.4 mm/s. Professional reel-to-reel audio tape runs at 15 or 30 IPS; consumer tape decks at 1⅞ IPS; VHS at ~1.3 IPS. High-speed CNC axes rapid at 800-1,200 in/min ≈ 13-20 in/s. Pneumatic cylinder speeds and robotic end-effector approach speeds in US assembly plants are programmed in in/s. 1 in/s = 0.0254 m/s = 5 ft/min.
About Metres per Second
The metre per second (m/s) is the SI unit of speed. Brisk walking ~1.4 m/s; Usain Bolt's peak sprint ~12.4 m/s; speed of sound in air at 20°C 343.2 m/s; in water 1,481 m/s. Rifle muzzle velocities 370-1,200 m/s. Speed of light = exactly 299,792,458 m/s (the defined constant from which the metre is derived since 1983). 1 m/s = 3.6 km/h = 2.23694 mph = 1.94384 kn.
