About Meter per Second (m/s)
The SI derived unit of speed (and velocity magnitude) per ISO 80000-3 §3-8, derived from the SI base units of length (meter) and time (second). m/s is the universal unit in physics, classical mechanics, fluid dynamics, kinematics, and sound propagation — every equation of motion (v = v₀ + a·t; v² = v₀² + 2·a·Δx), Bernoulli's equation, Navier-Stokes momentum equations, and ideal-gas-kinetic-theory velocity formulations assumes m/s unless explicitly stated otherwise. Reference values: human walking speed 1.2-1.5 m/s (per ISO 7176 wheelchair-accessibility studies + ADA walkway-grade limits); human running 5-12 m/s (Usain Bolt 100 m peak ~12.2 m/s; marathon pace 5.5 m/s); highway driving 25-35 m/s (60-80 mph); commercial jetliner cruise ~245 m/s (Mach 0.8 at FL350 -57 °C); speed of sound in air at sea level 343 m/s (at 20 °C, 50% RH per ISO 9613); speed of sound in seawater ~1,500 m/s (used in sonar per Mackenzie equation); speed of light in vacuum c = 299,792,458 m/s (exact per 1983 BIPM definition); Earth orbital speed around Sun 29,780 m/s; ISS orbital velocity 7,660 m/s; escape velocity from Earth surface 11,186 m/s. CFD solvers (ANSYS Fluent, OpenFOAM, STAR-CCM+) report velocity output in m/s by default in SI mode.
About Mile per Hour (mph)
An imperial unit of speed equal to exactly 0.44704 m/s per NIST SP 811 (1 mph = 1,609.344 m / 3,600 s). mph is the dominant unit for: US, UK, and US-territory road traffic (US Interstate highway speed limits 55-85 mph by state; urban limits 25-45 mph; school zones 15-25 mph per FHWA Manual on Uniform Traffic Control Devices MUTCD); US aviation airspeed reporting alongside knots (FAA Part 91 + commercial cockpits show indicated/calibrated/true airspeed in knots primary, but ground-speed and weather-radar wind in mph on flight-tracking apps); US and UK wind speed reporting (NOAA NWS forecasts in mph; Saffir-Simpson hurricane scale Category 1 = 74-95 mph; Category 5 = ≥157 mph; tornado EF-scale EF5 winds >200 mph); MLB pitch speeds (fastball typically 90-100 mph; record 105.8 mph Aroldis Chapman); auto-racing top speeds (F1 ~230 mph straight-line peak; IndyCar ~240 mph at Indianapolis; NASCAR ~200 mph). Converting mph to km/h (multiply by 1.609344) is one of the most frequent unit conversions for international travelers and drivers at US/Canadian or UK/European borders where signage switches units. Convert mph to m/s by multiplying by 0.44704; to knots by multiplying by 0.8690.
