Understanding Speed Conversions

Speed conversion is essential for understanding velocity measurements across different systems. The base unit is meters per second (m/s).

m/s (Meters per second): Base SI unit for speed
km/h (Kilometers per hour): Common in metric countries, 1 km/h = 0.2778 m/s
mph (Miles per hour): Used in US and UK, 1 mph = 0.447 m/s
Knots: Nautical miles per hour, used in aviation and maritime, 1 knot = 0.514 m/s
ft/s (Feet per second): Common in engineering, 1 ft/s = 0.3048 m/s
