From

Mach

Mach is the ratio of an object's speed to the local speed of sound. Mach 1 at sea level in standard conditions = 1225 km/h (340.29 m/s). Supersonic starts at Mach 1; hypersonic at Mach 5. The Concorde cruised at Mach 2.04; the X-15 reached Mach 6.7.

Real-world: Concorde: Mach 2.04. F-16 fighter: Mach 2. SR-71 Blackbird: Mach 3.3. Space re-entry: Mach 25+.

Foot per Second

ft/s

Feet per second (ft/s) is used in some US engineering, ballistics (bullet velocity) and older US physics textbooks. Typical handgun muzzle velocity: 1000–1400 ft/s. Rifle muzzle velocity: 2500–3500 ft/s.

Real-world: 9mm bullet muzzle velocity: ~1150 ft/s. .308 rifle: ~2700 ft/s. Free fall terminal velocity: ~195 ft/s.

Tips & common mistakes

Quick tips

Mach 1 = ~1225 km/h at sea level, standard conditions.
Local speed of sound decreases with altitude (colder air) — true Mach value varies.
Mach 0.8+ is "transonic"; Mach 1+ supersonic; Mach 5+ hypersonic.

Avoid these

Assuming Mach 1 is a fixed speed — depends on altitude and temperature.
Multiplying Mach values as simple ratios across altitudes.
Using Mach for subsonic everyday speeds — not practical.
