About both units

From

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.

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

1 km/h = 0.2778 m/s. Divide by 3.6 for m/s.
1 km/h = 0.621 mph. Multiply by 0.62 for a quick mph estimate.
Speed limits: 30 km/h urban, 50 km/h town, 80–100 km/h rural, 110–130 km/h motorway in most of EU.

Avoid these

Using mph values on a km/h speedometer — may misread actual speed.
Converting km/h to m/s by dividing by 3 — correct is 3.6.
Ignoring "E" for exit or other signs while focused on speed limits.
