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.

Beaufort Scale

Bft

The Beaufort scale is an empirical wind-force scale from 0 (calm) to 12 (hurricane). Created by Francis Beaufort in 1805, it correlates wind force with observed effects on sea or land. Force 8 (34–40 knots) is a gale; force 12 is above 64 knots.

Real-world: Force 5 (fresh breeze): 17–21 knots, white-caps form. Force 8 (gale): 34–40 knots. Force 12: 64+ knots.

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.

Frequently asked questions

How many Beaufort in a kilometer per hour?
