About both units

From

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.

Kilometer per Hour

km/h

Kilometres per hour (km/h) is the standard speed unit in most of the world. European motorways typically allow 120–130 km/h; urban limits are 50 km/h. Car speedometers in metric countries are marked in km/h, often with smaller mph numbers for US and UK travel.

Real-world: German Autobahn typical speed: 130 km/h (recommended) to 180+ (no limit sections). French limit: 130 km/h. Urban: 50 km/h.

Tips & common mistakes

Quick tips

1 ft/s = 0.3048 m/s = 1.097 km/h = 0.682 mph.
Multiplying ft/s by 0.682 gives mph.
US engineering often uses ft/s; metric countries use m/s.

Avoid these

Confusing ft/s with fps (frames per second in video/gaming).
Mixing ft/s with mph without conversion.
Using ft/s instead of m/s in international scientific contexts.
